These are the technical parameters of the Character LCD Modules

Viewing area
The size indicated on the LCD display screen is actually can use the same range. For example, a 15.1-inch LCD monitor is approximately equal to the visual range of a 17-inch CRT screen.
Viewing Angle
LCD viewing angle, symmetrical, up and down is not necessarily symmetrical. For example, when the the backlight incident light through the polarizing plate, a liquid crystal alignment film, the light output will have a lot of the directional characteristic, that is, most of the light emitted from the screen with a vertical direction. From a very oblique angle to watch a full white screen, we may see a black or color distortion. Generally, the vertical angle is less than or equal to the right at an angle. If the visual angle of about 80 degrees, which means that you can clearly see the screen image begins with the the screen normal 80 degrees. However, due to the range of vision, if there is no standing within the optimal viewing angle, can see the color and brightness there will be errors. Some manufacturers on the development of a variety of wide viewing angle technology, trying to improve the viewing angle characteristics of the liquid crystal display.LCD module
Dot pitch
We often ask to the dot pitch of the liquid crystal display is much, but most people do not know how the value is obtained, let us now take a look at whether it is how to get. For example, the general 14-inch LCD viewing area 285.7mm × 214.3mm, its maximum resolution to 1024 x 768 dot pitch equal to: the visual width / horizontal pixels (or the visual height / vertical pixels) that 285.7mm/1024 = 0.279mm (or 214.3mm/768 = 0.279mm).Tsingtek
Degree of color
LCD, of course, is the degree of color performance. We know the nature of any kind of colors are red, green and blue three basic color composition. By 1024 × 768 pixels on the LCD panel imaging, each independent of the color of a pixel is composed of red, green, and blue (R, G, B) controlled by the three basic colors. Most of the manufacturers of liquid crystal displays, each of the basic colors (R, G, B) of 6 bits, i.e. 64 kinds of performance of each individual pixel, there are 64 × 64 × 64 = 262144 colors. There are also many manufacturers have spent so-called FRC (Frame Rate Control), the simulation exhibit full color screen, that is, each of the basic colors (R, G, B) to 8 bits, i.e. 256 performance , then it is up to each individual pixel 256 × 256 × 256 = 16777216 colors.
