AI Technical Summary

Problems solved by technology

Since the measurement takes a long time and will increase the amount of data processing, if the number of measurements is reduced, the amount of data processing will not meet the requirements of compensation accuracy.

Embodiment Construction

[0029] Embodiments of the present invention provide an image display control method and device, which are used to achieve uniform image display without image sticking through a high-precision, high-efficiency, and low-cost compensation method.

[0030] The brightness of an image is determined by the grayscale. Here is a brief introduction to the concept of grayscale.

[0031] Usually, a point on the image displayed by the display device we see is composed of three sub-pixels of red, green and blue. The light source behind each sub-pixel can display different brightness levels. The gray scale represents the brightness from the brightest to the darkest. Different levels of levels, the more levels, the finer the picture effect will appear. For example, 256 brightness levels are called 256 gray scales, and the color change of each point on the image represents the change of the gray scale of the three sub-pixels that constitute this point.

[0032] The same gray scale of the back...

Abstract

The present disclosure discloses a method and an apparatus for controlling image display, which achieve uniformity of image display and remove the image-retention in a compensation manner of high precision, high efficiency and low cost. The method for controlling image display comprises: reading gray scales of all sub-pixels of a current frame image displayed by a display device; determining an ideal luminance corresponding to the gray scale according to a predetermined ideal corresponding relationship between the gray scales and luminance of respective sub-pixels respectively; determining an adjusted gray scale corresponding to the ideal luminance according to the predetermined original corresponding relationship between the gray scales and the luminance of respective sub-pixels respectively; driving the display device to display the current frame image according to the adjusted gray scale.

Description

technical field [0001] The present invention relates to the technical field of image display, in particular to an image display control method and device. Background technique [0002] Organic Light Emitting Diode (OLED) display devices are considered to be next-generation dreamy display devices due to their advantages such as high color saturation, large viewing angle, low energy consumption, high brightness, and simple device structure. [0003] At present, there are still two problems in display non-uniformity and afterimage in terms of brightness in realizing large-size OLED display devices. The display non-uniformity of brightness is mainly caused by the non-uniform electrical performance of the thin film transistor (Thin Film Transistor, TFT) in the backplane and the power supply voltage drop (IR Drop) generated when realizing image driving. Image sticking is image sticking caused by the aging of OLED and TFT devices, which is mainly caused by the attenuation degree o...
