3.3: Real Time Brightness Compensation for a‐Si:H TFT Backplane AMOLED

Chang-Heon Kang¹,

et al.

Abstract: a‐Si:H TFT backplane based AMOLED with a real time brightness compensation circuit is presented. The brightness of AMOLED is automatically adjusted by the thermal sensor and temperature compensation system with feedback algorithm. By using this compensation circuit, the brightness differences over the temperature range −20 °C and 60 °C is reduced by 550cd/m2 to 30cd/m2.

The luminance of AMOLED displays varies depending on the temperature owing to panel degradation. In this paper, a luminance compensation method using a monitor pixel with a multiple output boost converter and DAC for digital driving scheme is introduced. This method makes the panel luminance constant irrespective of the temperature. Furthermore, it has lower power consumption compared with the previous compensation method using monitor pixel.
