LY-LCD public display module mainly applied in large public places such as airport, station, wharf to show the information about flight or train.

Characteristic comparison of LY-LCD module product and LED 
 
 If the LED is displayed in a fixed mode for a long time, the performance of the components constituting the lamp is deteriorated, and then the bright spot phenomenon occurs. In addition, LED is displayed by continuous light, the lamp in the non-light state will not be identified finally. In this case, because the LED can not be replaced as a lamp unit, it is necessary to replace the entire component.
Compared with the LED, the LCD components our company produced use LCD as the optical switch, and use multiple LED tube as a back light source, and the situation of the individual LED lamp does not shine does not appear to be unrecognizable phenomenon. Ordinary LED display is a point-to-point display, a group LED display failure will affect the complete display.
In addition, in terms of MTBF using the fault period, compared to the whole face with LED tube laying the general LED components, LY-LCD average trouble-free time to upgrade 3 times (comparison between the full color LED components).Our product has a very high stability. For example: LED display 24 * 24 pixels need to use 24 * 24 = 576 group RGB LED to driver. And LY-LCD use backlight 16 * 8 = 128 group RGB LED, the ratio is 576: 128 = 4.5: 1 and comprehensive parameters summed up: 3 times.
 

Characteristic comparison of LY-LCD module product and traditional LCD 
The traditional LCD use white backlight and display the color by the color filter formed in the LCD panel. The color display principle is very different with our LCD. In addition, it needs to decompose every 1 dot matrix into RGB, which inevitably leads to the change of the display aperture rate according to the color. This is also the reason why it has a low contrast and viewing angle range. In contrast, our company's LCD use colorless color filter, LCD panel does not exist in the color filter.
Principle about luminous: use of high life, high efficiency LED tube, and use our company's unique surface-emitting backlight, through the RGB color display to control color.
LCD only play a role in the shutter, showing the aperture rate does not depend on the display color, so the product has character like excellent display color, high contrast, wide viewing angle range.
 
The chip of RGB three colors were independently composed, through the Red, Green, Blue three kinds of color LED constitute a color mixing, and then the occurrence of stains. But if RGB in each chip mixed color light, which also eliminates the stain.

Have a high degree of recognition, meticulous care of your eyes.
Sequential scan color display
Rely on the rapid response of the LCD panel, to achieve the multi-color display in the same area. Without color filter to achieve color display, the display color display aperture ratio is exactly the same, thereby improving the recognition.
Broad perspective
By developing FTN-based liquid crystal based on wide viewing angle film, the color difference at various angles is reduced.
High contrast
Through the FTN LCD and high efficiency LED backlight development, to achieve a high contrast.
Quick response
Using the most suitable liquid crystal panel material, in order to achieve a rapid response to the display and make the scroll display is also possible.
Suitable for large display devices
Rely on our company's own LCD manufacturing technology, can reduce the color difference between the modules, can be combine in multi-line, multi-stage equipment.
Easy to maintain
Specially designed backlight structure, making the backlight repair and other maintain work easier.
Backlight remote dimming function
 According to the external signal, you can adjust the color and brightness.
