Storage temperatureTSTG-3080°C(1)
Operating temperatureTOPR-2070°C(1,2,3)
Note (1) 95 % RH Max. ( 40 °C ≥ Ta ). Maximum wet-bulb temperature at 39 °C or less. (Ta > 40 °C) No condensation.
Note (2) In case of below 0°, the response time of liquid crystal (LC) becomes slower and the color of panel becomes darker than normal one. Level of retardation depends on temperature, because of LC's character
Note (3) Only operation is guarantied at operating temperature. Contrast, response time, another display quality are evaluated at +25°C.

a.Test equipment setup
After stabilizing and leaving the panel alone shall be warmed up for the stable operation of LCM, the measurement should be executed. Measurement should be executed in a stable, windless, and dark room. Optical specifications are measured by Topcon BM-7(fast) with a viewing angle of 2 at a distance of 50cm and normal direction.
b.Definition of response time: Tr and Tf
The response time is defined as the following figure and shall be measured by switching the input signal for “black” and “white”.
c.Definition of contrast ratio:
d.Measured at the center area of the panel when all the input terminals of LCD panel are electrically opened.

FAQ
1.What does TFT screen mean?
Short for thin film transistor, a type of LCD flat-panel display screen, in which each pixel is controlled by from one to four transistors. The TFT technology provides the best resolution of all the flat-panel techniques, but it is also the most expensive. TFT screens are sometimes called active-matrix LCDs.
2.What is a TFT screen used for ?
thin film transistor liquid crystal display (TFT-LCD) is a technology which is used in LCD monitor and television displays. TFT technology can be used to give one of the clearest pictures of any flat screen display and it uses much less electricity than older screens.
3.Which is better TFT or LED?
A TFT means ThinFilmTransistor which may refer to an ordinry LCD screen. Both the TFT and LED displays are made of LCD, but the difference only comes in the backlightig. LCD/TFT uses CCFL(cool compound fluroscent lamp) while the other uses LED to backlight. ... But perfomancewise LEDs are far better than TFT displays.
4.What is TFT color?
A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast.Small Tft Module manufacturers
