For the current terms of LCD monitors, LCD viscosity, response time and quality has a very close relationship between.
Because, LCD sticky, the colors on bright, but the response time is slow; while the LCD thin, and fast response time, but the color fades. The high voltage can achieve higher response rate, no doubt. However, the characteristics of the liquid crystal molecules are obtained at different voltages in different colors, so that the voltage is the result not only raise the color is incorrect. Therefore, using the same materials of the same generation OLED Module, fast response for gamers, slow response times and better color performance 2D display sharper, more suitable for graphic design and office, Internet application.
Grayscale 4m s become mainstream
Most commercially available liquid crystal display nominal response time between black and white is the time required for conversion, of course, is the fastest LCD black and white conversion and not the slowest. LCD conversion between other colors, such as white to gray, red to blue, etc., than between black and white shift needed for a long time. A nominal 12m s LCD display, display the red dot blue dot to become time may be required for several tens of milliseconds or more. When playing games or watching movies, the screen content can not just do the darkest switching between white, but colorful colorful screen or different shades of gradations, these are doing grayscale conversion between.
As people requested more "harsh", 8m s, 5m s gray level response time of lcd moduleproducts in the market is just too short-lived, less gray 4m s products have become the dividing line between the mainstream market, adapt to this market demand , manufacturers introduced 4m s even lower gray response time of LCD products, they have gradually appeared on the market. Since 19 inches this grayscale LCD product prices are relatively high, so users are generally 17 inches or optional objects, in this small series at 4m s elected several gray response time of less than 17 inches LCD products, so that consumers who also feel this "speed experience."

Self-leveling epoxy coating introduction Character LCD Modules
Clean-resistant epoxy self-leveling epoxy floor coating is a coating film-forming material, and then by adding a curing agent, non-volatile reactive diluents, additives and pigments and fillers preparation of a solvent-free high performance coatings. Epoxy self-leveling coating film forming process is a chemical method, first the soluble low molecular weight epoxy resin is coated on the substrate surface, graphic lcd
modules leaving the reaction between molecules to further increase the molecular weight or the formation of crosslinking tough film. Where the optional requirement epoxy resin can be at room temperature deposition, and the coating film is required to have a viscosity relay, strong mechanical strength, chemical resistance and good electrical properties.
Comparison of domestic self-leveling coatings
Coating after the construction can achieve smooth feature called leveling, leveling coating applications is a very important issue, and it affects the apparent gloss coating, when the paint brush to the substrate, will leave brush marks, this brush marks may be due to the flow of paint dried before mitigated. When the coating is poor leveling, can be seen with the naked eye in the case uneven coating. When the difference to the naked eye can not see, at this time, said the film is flat, Graphic LCD Display smooth coating to the uneven gravity is not the driving force, but the surface tension, under normal circumstances, leveling can be used ORCHARD formula evaluation. Theoretically, the lower the viscosity paint or coating the thicker the better leveling. Because self-leveling coatings particularity, the general requirements of the film after the film has good leveling, while simultaneously maintaining good surface properties. Throughout the current domestic and self-leveling epoxy material system, there are two main technical guiding ideology, one of many domestic manufacturers generally use the guiding ideology (A class), A class technology theme is: the use of an appropriate amount of solvent to achieve Good leveling coating, the coating process, the coating of filler will gradually decline, the cured film has good leveling, but the surface hardness, wear resistance is poor, while in the construction may be will produce more spots such as lack of surface flaw, which is one-sided pursuit of leveling results; Second, foreign technology and many other manufacturers follow (B class), while class B self-leveling resin coating is to ensure good leveling while still maintaining the uniformity of the filler, the cured coating film so as to ensure better apparent decorative.

Clean plant ventilation engineering controls Character LCD Modules
General plant operating environment of harmful substances generated in the generating source will spread through the propagation path of the job, and they therefore operating environment from the generating source control strategies, dissemination and acceptance of the diffusion path by three aspects of exposure to exercise control, Character LCD
Module to the extent that Engineering control point of view, it is best to place the occurrence of pollutants polluting substances will be controlled by the nearest treatment, to avoid spread of harmful substances. In order to ensure the safety and health staff and good working environment, should be engineering to improve its operating environment for harmful gases, vapors or dust, etc. The improved operating environment, can be combined with one or two kinds of ways to address hazardous substances exposure hazard.
First, the overall ventilation system
Plant anti-ventilation control mode ventilation primarily as a whole (dilution ventilation) and local exhaust two main forms. Where ventilation is the most basic type of overall ventilation system, its main function is to provide fresh outside air at the workplace, workplace hazardous dilute the concentration of harmful substances and by the flow of air from the outdoors. Therefore the relationship between air and harmful substances, the overall ventilation consists of two basic mechanisms: mixing and displacement. The former so that fresh air and polluted air mixture to achieve dilution effect, the latter is replaced by the contaminated air with fresh air.lcd module In occupational safety and health regulations, decrees concerning ventilation ventilation devices are set on the overall timing, principles and basic performance requirements vary specifications. However, the air flow pattern in the room, the ventilation performance of the overall impact of a quite significant, and often can not be certainty factor. Indoor geometric state, cubicles, equipment, furnishings, temperature, pressure distribution, intake and exhaust port configuration and human caused deliberately forced ventilation are all factors that influence indoor air.
Overall ventilation in different occasions for different interpretations and calculations. Such as to control indoor air quality (Indoor Air Quality, IAQ) as the goal, the overall ventilation is to provide fresh air to maintain proper temperature and humidity in order to achieve a comfortable purpose; while controlling operating environment is the prerequisite of fresh air dilution when ¸ places polluted air, in order to achieve the purpose of industrial safety and hygiene. As the air from the high pressure to low pressure with the flow characteristics, in order to consider the plant's distribution and airflow poorly ventilated place to avoid the accumulation of harmful substances, generally we all hope to send, mechanical ventilation are implemented and enforced by the air supply, exhaust pipe system design arrangements to dilute the concentration of harmful substances, such as properly designed on the occurrence of a small amount of low concentrations of widespread non-toxic or low toxic pollutants exclude extremely effective. ¸ pollution control effectiveness in accordance with the United States Institute of Industrial Safety and Health ACGIH (American Conference of Governmental Industrial Hygienists) study, the overall ventilation less suitable for the workplace dusts or fumes, which are usually larger because of its toxicity. If you need to use a whole lot of ventilation equipment ventilation and general dust, fume generated a large amount of speed, and therefore vulnerable to localized high concentrations of circumstances, this device can not be controlled. So this is not a ventilation system ventilation design engineers will first consider the use of the design, but this device for generating source pollution harmful or even widespread occurrence of uncertain location of the position, as a very practical in the solution. Consider different sources in different environments required overall ventilation design, we must first consider the calculation of the amount of ventilation, the current overall ventilation ventilation calculation method according to (1) the number of the operator (2) in the workplace space (3) evaporation rate is subject to limits (Threshold Limit Value, TLV) and the minimum Explosive Limit (Lower Explosive Limit, LEL) and other different conditions were estimated.

Connecting technology of liquid crystal TFT Display Module device
Liquid crystal COG LCD
Module device by the two glass. The outer lead is attached to the surface of the transparent conductive film made of photolithography, can not use the conventional welding processes. Currently there are connection process:
1, the conductive rubber connector
This is a more traditional way. Conductive rubber strip all known as zebra conductive rubber strip is determined by a layer of conductive rubber, a layer of insulating rubber white laminated into a very thick one, and then in the direction perpendicular to the surface of the rubber strip cut into strips. When used, just outside the lead and the liquid crystal display circuit board traces correspond neatly side, the Zebra caught in the meantime, to fix them. To do this, we must make a pressure box. Pressure frame material shape can be any design, but must ensure that there is a pressing amount to about 0.2mm, the need to ensure that the pressure uniform, not bent.
2, the metal pin connector
Stamping into the metal pins, the first liquid crystal display which plug member fixed to the end of the outer lead, to the user, or when soldered or plugged into the circuit board.
These two methods more used digital type, the outer lead much (line pitch> 1.25mm or more) of the liquid crystal display device.
3, hot film flexible connection
Calculators and digital communications equipment commonly used. Its hot conductive connection with a polyester film, in the intervals of graphite printed on a thermal conductive adhesive strips and insulation. When used, the end of the alignment of the liquid crystal display device of the conductive strips of the outer lead securement, plus potential, pressure, and the other end of the conductive stripe aligned snapping lead terminal board, heat and pressure can. Since it takes a certain pressure and temperature, so users need to configure a dedicated hot press.
4, the anisotropic conductive adhesive connections
The so-called anisotropic conductive adhesive is shown in Figure 1 as a hot film. Interspersed with gold plated film in plastic balls, to be sandwiched between the LCD and PCB heat and pressure, the lead because of the thin film pressure, and connected by a conductive plastic ball, since the lead spacing, so it will not horizontal concatenation. So called anisotropic conductive connection. Also known as TAB connection. This connection can easily connect line spacing device is only 0.1mm. Is the high density and large amount of information necessary for connecting liquid crystal lcd module technology. Because it requires precision alignment and precise pressure, temperature control, you need to set the price of expensive special equipment job.
Connection with TAB method the chip directly on the liquid crystal display device on the glass COG mounting method, the pressure in the chip from the board COB hard wire and the chip mounting pressure in the flexible circuit board COF mounting.

LCD oled module design should pay attention to several issues
With the rapid development of information industry, as one of the terminals of the LCD information display device has also been an unprecedented development. In the FPD (Flat panel display) devices, LCD with its light, thin, small, and low power consumption and thriving.
For LCD driver circuit is configured to form a LCD module LCM (Liquid Crystal Module). In addition to its basic component parts LCD, driver circuit and connector outer Usually, backlight. TFT LCD Display in the same system as other circuits, has a simple interface, and provides a wealth of control display instruction system.
Contrast
Contrast is the description of a display device in the display when the foreground (such as display text, graphics, etc.) and the difference in brightness between the background the size of a volume.
● driving waveform to improve
As a general module circuit design is relatively simple, no electromagnetic interference analysis. However, the product at high duty cycles, the oscilloscope can be found in the chip of the output waveform tends to become poor, the contrast of the display which have a certain extent. In order to change this situation, each resistor in the bias circuit capacitor in parallel with a 0.1μF can improve the output waveform.
To output B-wave chips COM line as an example. In the absence of additional capacitance and a half before the selection point selection point voltage waveform has distortion, distortion can cause severe crosstalk display contrast, the waveform shown in Figure 2. Increase the capacitance, the waveform would have been greatly improved.
● Working frequency problem
In actual debugging a display capacity of 128 × 64 dot matrix display module samples, discovery module in interlaced OLED Display Module, the display was pale, contrast is poor. The analysis that there are two ways to solve. First, adjust the module RC oscillator circuit, reducing the resistance R, the oscillation frequency is increased from 47kHz down to 20kHz; Second, in the bias circuit section to be the driving circuit (as described above). Both approaches achieve the desired effect. But the first approach due to lower operating frequency module, which will display the frequency is also reduced Zhen, which resulted in the entire LCD screen display when the same as the TV screen flicker generated phenomenon, which under fluorescent light observation easier to find, but in natural light or incandescent display is pretty ideal, in the actual commissioning according to the actual situation, select the

Overcome cross effects Character LCD Modules
In the dynamic drive mode, to make such a position (i, j) point display, on the need in the i th column and j th row selection voltage is applied at the same time, so that the point of the maximum electric field strength, but this time in addition to (i, j) points, the i-th row and j th row of the remaining points can withstand a certain voltage, these points are called semi-selected point. If the semi-selected point of the effective voltage is greater than the threshold voltage, there appears on the screen should display the contrast decline, which is cross effects. The way to solve the cross effect is the average voltage method, that is, the semi-selected point and non-selected point average of the voltages, an appropriate increase in the non-selection voltage to offset the point on the semi-selected point of the voltage, the semi-selected point on the voltage drop, improve display contrast.
Pixel Control
Pixel by pixel register and a status bit is uniquely determined. There are 16 pixel lcd module registers to control up to 4 × 29 = 116 pixels. We use the LCD from 8 × 8 = 64 pixels. Thus, the pixel data register is sufficient.
Segment Enable
Segment code is enabled by LCDSE registers. Because VIM807-2 is eight 7-segment display, and our choice is 1/3 duty cycle (ie, three common), so by LCDSE register must choose 3 × 8 = 24 segments in order to meet the need, namely complete expression All of the code segment pixels. Of course there will be superfluous, 8 × 9 = 72, because every three commons and 3 above can express 9 pixels.
LCD drive voltage generating
LCD drive voltage is generated in two ways, the internal charge pump method or external resistor ladder network method. Since the Character LCD Module charge pump is in development, in order to reduce design risk, we use a more sophisticated method of external resistor ladder network. Using an external resistor ladder network, VGEN (LCDCON <4>) should be cleared.
