Our introduction of new equipment to enhance the quality backlight TFT Display Module

Our introduction of new equipment to enhance the quality low temperature lcd display.Prior to this, most of the Division I and backlight manufacturers , are printed using a silk screen backlight outlets way to produce Tsingtek lcd graphic display modules , however, often have customers reflect uneven backlight brightness , brightness dim , based on this , the company leadership decided introduction of new equipment to improve the backlight problem. December 2013 , the company invested more than 300 million yuan to introduce 10 sets of laser engraving machine, using laser engraving outlets backlight with graphic lcd display module , brightness uniformity, no dark areas , not aging long life, environmental protection and other advantages. The introduction of the device greatly improves the backlight production processing efficiency and quality for our company manufacture backlight provides favorable conditions , greatly enhance the quality of the backlight.

The relations between and among the Character LCD Modules , LED, OLED

LCD is composed of a liquid crystal liquid crystal display, and LED is composed of light emitting diode display. 

LED display compared with LCD, color LCD display in brightness, power consumption, the visual Angle and the refresh rate, etc., are an advantage. 

But using LED back light screen in color saturation is not enough, in part of the screen color display when you least expect them to 

Slight deviation, especially in the touchpanel LCD module screen folding place color deviation is more apparent. 

OLED display technology and the traditional LCD display in a different way, no need backlight, with very thin organic materials coating and glass substrates, when a current through the organic material will glow 

Character LCD Modules screen working principle and characteristics

LCD screen working principle is to use the physical properties of liquid crystal, when the electric conduction, make character OLED arrangement orderly, make the light easy through; 

Without power, becomes chaos, prevent light through. The following about the characteristics of the LCD screen for you: 

Now very common. It has small volume, light weight, save electricity, low radiation, easy to carry, etc. The principle of liquid crystal display (LCD) 

Very different from a cathode ray tube (CRT) monitor. lcd character display device is based on liquid crystal electro-optic effect. The way of display characters display device including; 

Matrix display of characters, graphics, image display device; Matrix display of large screen LCD LCD projection TV, etc. 

Character LCD Modules dot defect analysis and research

LCD panel in the manufacturing process, which can be roughly divided into three stages: array (array), into the box (cel1), the module (module). Although most of LCD panel manufacturing process 

Is done in the high cleanliness of the clean room, but still inevitably on the custom LCD display will appear some defects. There are many reasons that cause these defects, in all of its manufacturing 

A link has defects. In a box of phase formation of the pinhole defect and black dot defect is two more common point defects. 

When perfusion liquid crystal box if vacuum bubble, namely the pinhole defects; If some particles in perfusion liquid crystal before the supers group (particle cluster), either 

When pouring the serial LCDs crystal box were mixed with some particles, which cause the black point defects. 

Point defects at the core of the will of the surrounding have anchoring effect of the liquid crystal molecules, so will inevitably shadow Ⅱ to the liquid crystal molecules are arranged in certain ranges. Based on two typical point defects 

Core research, found that the different defects affect the ability of the liquid crystal molecules are arranged around there are significantly different, and through the extrapolation length theory and elastic long-range correlation theory into the phenomenon of the experiment 

Line of argument. 

2014 ultra-small size mobile phone shipments flat Character LCD Modules screen tablet

2014 ultra-small size mobile phone shipments flat Touch screen LCD tablet 12864

In the past been considered ridiculous tablet phone , and now because of the success of the Samsung Galaxy Note series , and thus promote the 5-inch screen size of smart phone market, especially showed significant sales growth in Asia, Europe and Brazil and other markets. Taiwan media reported on December 23 , correlation analysis, flat mobile phone sales are expected to exceed the small size of the plate in 2014 , to reach 17.5 million units. Analysis pointed out that the global mobile phone sales are expected to grow flat to 17.5 million units in 2014 , will be less than 8 inches tablet approximately 16.5 million small number of units , indicating the global market demand for large-size mobile phones showed positive growth , particularly in Asia , markets such as Europe and Brazil have significant market demand, but this year has gradually led five inches above aircraft sales.

  Mobile phone market has been flat over the past considered a joke look at, but in the mobile Internet , social applications , online shopping and games using behavior change ,LCD Manufacturer market is also increasing demand for large-size phones . And after Samsung launched its first Galaxy Note has achieved success based on the market now includes LG, Sony Mobile, Huawei , HTC, Nokia has launched tablet phones etc , and even mainstream flagship models were also introduced more than 5 inches screen size . The 3.5-inch screen in the past and always adhere to the design of the Apple iPhone, iPhone 5 , first to 4 inches in screen size , is also rumored to be in the new iPhone 6 design with larger screen sizes .

Tablet PC Character LCD Modules panel shipments remained high BOE win

Tablet PC LCD panel shipments remained high BOE win

According to NPD DisplaySearch latest monthly tablet computer shipments and value chain reports Monthly Tablet PC Shipment & Value Chain Report noted that in September 2013 Tablet PC panel shipments to 28 million tablets, unchanged from last month . But already the second month in a single month record high 28.0 million tablets shipped . serial LCDs DisplaySearch analysis, September 2013 Tablet PC panel shipments were flat for the following reasons : Some computer brand plans to launch new models in the upcoming tablet computer Thanksgiving and Christmas sales season . They do this with mass production in August, September, flat panel and assembled in October through graphic LCD, to prepare for November and December market. So consumers will see many new products in the next marketing season , when choosing gifts for family and myself have more choices.

 Apple's new iPad Air 9.7 inch panels from small shipments began in August , September, October substantial growth while continuing to increase. However , due to the iPad Air panel yield less than iPad 4, while labor shortages in mainland China after the National Day , so the iPad Air panel shipments in September is still less than the iPad 4. In addition, part of the 7.9 -inch mono LCD display 2 panel , to the end of September , only South Korean panel makers will be 7.9 '' retina panel on the market, but shipments of less than 100 million units in September , October is expected to be increased . Because yield issues remain unresolved , the Japanese panel makers still can not successfully be 7.9 inches retina panel volume production.

  Thus , Apple is likely to make another Korean panel makers have begun to supply. Although this situation is not expected to happen this year , that the Japanese panel makers should be smoothly 7.9 "iPad Mini 2 retina panel into volume production in the fourth quarter .

  Whitebox tablet PC panel shipments continue to rise , mainly because of the panel and system manufacturers to provide low-cost chip prompted a large number of mature local dealer to buy a lot for the end of the sales season and prepare for the Chinese New Year . These low-cost tablet computer often as a gift , or corporate incentives and so on.
