Abstract

The invention discloses a control system for an AMOLED display screen, comprising: a main control chip, which sends image display signals and brightness control signals; a driving chip, which receives image display signals and brightness control signals, and sends data signals to the AMOLED display screen, and scans and controls signal and brightness signal; the main control chip has two settings; the driver chip includes a register that stores the correspondence table between the number of refresh frames and the brightness value; when the main control chip switches to the second display mode, the main control chip stops sending the brightness control signal , and optionally send an image display signal, and the driver chip selects display data from the register to update the data of the AMOLED display. The beneficial effect of the present invention is that by setting the register in the driver chip and storing the frame number-brightness comparison table, the main control chip does not need to send the brightness control signal and the image display signal in real time, and the power consumption is reduced on the basis of ensuring the display effect. The light-emitting time of the pixels is reduced, and the burn-in phenomenon of the display screen is delayed.

Description

technical field [0001] The invention relates to the field of AMOLED display, in particular to a control system of an AMOLED display screen. Background technique [0002] In recent years, with the development of display technology and the application of new materials, AMOLED displays have been widely popularized. [0003] In the field of existing display technology, many manufacturers have researched many new applications based on the inherent characteristics of AMOLED displays, such as using AMOLED to control the light-on and off of individual pixels to achieve higher contrast and finer brightness control, such as using AMOLED to achieve Interesting screen display, reduce the overall power consumption of the display screen under specific needs, or use AMOLED to realize flexible display screen and so on. [0004] As for the screen-free display technology, the prior art usually chooses a low-brightness or low-frame-rate display solution, or adopts the same brightness as a nor...
