Environmental Data Memory and Display Status Monitoring Technology of Outdoor Display

Description:

This paper presents environment data memory technology and display status monitor technology developed by BOE in TFT-LCD outdoor display LCM. Add metal ring designed in panel BM used as resistance temperature sensor, MCU calculates the temperature data as panel environment data and stores it into a flash memory. According to the temperature value, if it is too high than specification, MCU controls to decrease BLU brightness or turn off the panel and BLU in order to protect LCM from higher temperature. Using MCU or TCON IC to detect panel driving electric signal and identify if the signal is normal or abnormal, based on this, different hexadecimal code is output to SoC to realize display status remote monitoring function.
