Abstract

The present disclosure provides a method and a control circuit for adjusting panel brightness of an organic light emitting display. The method for adjusting panel brightness of the organic light emitting display includes reducing the image brightness value according to a first ratio during a first sub-preset time interval, and reducing the image brightness value according to a second ratio during a second sub-preset time interval Image brightness value. The first ratio is not equal to the second ratio.

Description

【Technical field】 [0001] The present disclosure relates to the field of display technology, in particular to a method and a control circuit for adjusting panel brightness of an organic light-emitting display. 【Background technique】 [0002] Active Matrix Organic Light Emitting Diode (AMOLED) displays occupy the mid-to-high-end market in the panel industry, but active matrix organic light emitting diode displays require a high voltage, and the power consumption of handheld electronic devices is large, which affects The standby time of the device. [0003] In the past, the method of entering the energy-saving mode to adjust the brightness of the panel, such as figure 1 Shown: Stage 1, cyclically calculate the average image brightness (Average Picture Level, APL) value of the current frame, compare the APL value of the previous frame, if the APL value does not change within the time t1, then it is determined that the panel at this time The playback content is static, and no d...
