TFT display working environment and temperature control

The TFT display is the abbreviation of "Thin Film Transistor", which refers to the thin film liquid crystal display # LCD TFT 2.8 inch # , but actually refers to the thin film transistor (matrix) - which can "actively" control each independent pixel on the screen # LCD 2 inch #, This is the origin of the so-called active matrix TFT (active matrix TFT).

TFT is an active matrix liquid crystal display # 7-inch LCD screen #, which is technically driven by an "active matrix" method. The method is to use the transistor electrodes made of thin film technology, and use the scanning method to "actively pull" to control the opening of any display point. When the light source is irradiated, it first passes through the lower polarizer and transmits upwards, and uses liquid crystal molecules to conduct light, and achieves the purpose of display # 4 inches round LCD # by shading and transmitting light.

The TFT display improves the flickering (water ripple) blurring of STN, effectively improving the ability to play dynamic pictures. Compared with STN, TFT has excellent color saturation, reproduction ability and higher contrast ratio, but the disadvantage is that it consumes more power and costs more.

In addition to the length of time, the service life of the TFT display # 7 inch LCD screen replacement # is also related to the working environment of the display # 24 pin LCD 2.4 #. The working environment of the display screen # 20 pin LCD display screen # is generally: working temperature: 0 ~ 50 °C; storage temperature: -20 ~ 60 °C.

TFT displays are very picky about ambient temperature. Theoretically, at room temperature of about 25 degrees Celsius, its working state is ideal. But in fact, the ambient temperature of outdoor displays# TFT 9" #is quite complicated in application. The maximum temperature in summer may be above 60 degrees Celsius, and the minimum temperature in winter may be below -20 degrees Celsius.

If the display screen # 8 touch screen # is kept at a low temperature for a long time, and then placed in a room temperature environment, it is certain that the circuit board and the display screen# 2.1 inch display #will appear water vapor condensation. In this case, it is generally no problem to leave it at room temperature for about 30 minutes. If the monitor is left in a low temperature for a short period of time and then used at room temperature, there is not much problem. Even if there is a phenomenon of "solidification" of the display screen # 6 inch TFT LCD monitor #, it will disappear after a period of time.
