For high-brightness backlight, its power consumption is higher which generates more heat and requires a TFT display with higher temperate feasibility, especially these high-brightness TFT displays used for outdoor applications.

In order to keep its perfect sunlight readability, Bunsun’s most high brightness TFT displays are applying wide-temperature liquid crystal of TNI (110°C), to prevent black-spot problem might happen in direct strong sunlight.

High Brightness backlight is with disadvantage of high power consumption. For outdoor applications, it must require High-brightness TFT Display due to the bright and intense natural sunshine in daytime. But compared with sunny daytime, actually a lower brightness should be more fit when it is cloudy or foggy or at nighttime, because normal brightness is enough to read display content clearly and avoid uncomfortable reading experience of being dazzling. In this case, Bunsun suggest the solution of High Brightness TFT in conjunction with brightness sensor and our in-house designed TFT control board. According to the data from brightness sensor, the control board will automatically increase or decrease backlight brightness to better match ambient brightness, to prevent being blinding or dazzling. This ensure the display keep perfect sunlight readability status, meanwhile effectively save backlight power consumption and extend it’s lifetime.
