VA display panel in standard and custom size
VA LCD, also known as VATN, is short for Verticcal Align Twisted Nematic. This technology is different from the previous TN LCD twisted orientation technology, it does not need cross-polarizer. VATN can provide true black and white working mode, response speed is extremely fast, suitable for dynamic image display and large screen display is widely used in small household appliances, high-end instrument products on the display screen. VA LCD screen has a high contrast between black and white. Compared with other black and white words segment code LCD screen, VA LCD screen has a darker and purer background color. It has a good effect of color segment code LCD screen and the best screen printing effect. At the same time, VA LCD screen cost is higher than the ordinary material of the LCD screen.

FSTN display panel in standard and custom size
FSTN (Compensation Flim+STN) in order to improve the background color of ordinary STN, add a layer of compensation film on the polarizer, which can eliminate the dispersion and achieve black on white display effect. It has higher contrast ratio and wider viewing angle. It’s widely used in moblie phone, GPS systerm, MP3, Data bank and so on.

STN display panel in standard and custom size
STN panel (Super twisted nematic), the twisted orientation of liquid crystal molecules is 180~270 degrees. Avaliable for high multi-plex driving application. High number of channels, large information capacity, wider range of viewing angle than TN or HTN. Because of dispersion, the background color of the LCD screen will show a certain color, common yellow-green or blue, that is, usually called yellow-green model or blue model.Its biggest advantage is low power consumption, so it is quite energy-saving, but the response time of STN LCD screen is long, the fastest response time is generally 200ms, Often used in telephones, instruments, meters and other equipment.

HTN display panel in standard and custom size
HTN panel(highly twisted nematic) nematic liquid crystal molecules are sandwiched between two transparent glasses. Between the two layers of glass, the orientation of liquid crystal molecules is deflected by 110 ~ 130 degrees. so the viewing angle is wider than TN. Avilable for low driving voltage,low current consumptiion. High CR（contrast ratio） and low cost. Popular used in audio,telephone, instrument and so on.

TN display panel in standard and custom size
TN（ Twisted Nematic）which the orientation of liquid crystal molecules is 90°. Avilable for low driving voltage,low current consumptiion and low cost,but viewing angle &multi-plex dirving is limited. In addition, because the photoelectric response curve of TN liquid crystal is relatively flat, the display contrast is low. Popular used in watch, calculator, clock, meter, instruments.
In terms of the displayed response speed, TN panel can easily improve the response speed due to the small number of output gray classes and the fast deflection speed of liquid crystal molecules. In general, most LCD monitors with response speed below 8ms use TN panels. In addition,TN is a soft screen. If you tap the screen with your finger, you will have a phenomenon similar to water lines. Therefore, the LCD with TN panel needs more careful protection when using, to avoid pens or other sharp objects contact the screen, so as not to cause damage.
