The brightness of the outdoor TFT LCD screen refers to the brightness of the screen, and the unit is candela/square meter (cd/m2), that is, candlelight per square meter.
At present, there are two ways to increase the brightness of the TFT display screen，one is to increase the light transmission rate of the liquid crystal panel, and the other is to increase the brightness of the backlight. The following is a general description of how to choose the appropriate brightness for outdoor TFT LCD screens.
When the equipment is used indoors, the brightness of the TFT LCD screen is about 300nits, and the working temperature is 0~50°C. When using it outdoors, when there is a shelter or no shelter, and when there is a shelter, the brightness of the TFT screen is 500nits. It can be read from left to right, and the working temperature is -20~70°C. In another case, when there is no shelter at all, the brightness of the TFT LCD screen is above 700nits, the operating temperature is -30~80°C, and the LCD panel can be read outdoors.
When choosing a TFT LCD screen, it should be noted that a bright TFT screen is not necessarily the best TFT screen.The TFT display screen is too bright, which can easily cause visual fatigue. At the same time, the contrast between pure black and pure white is reduced, which affects the performance of color scale and gray scale.
The parameter of LCD screen brightness is the main parameter that affects the price of LCD. Therefore, when selecting a TFT LCD screen, it is not a high-brightness LCD screen that is directly selected, but an LCD screen with appropriate brightness according to the use environment.
