Problems solved by technology
However, due to the problem of different characteristics of thin-film transistors made by low-temperature polysilicon technology, it will cause vertical ripples in the display screen.
[0005] In order to solve the problem of vertical ripple, the conventional technology proposes a data voltage compensation method, which stores the threshold voltage and electron mobility value of each pixel when displaying each gray scale, and compensates the input voltage through the threshold voltage and electron mobility of each pixel. The pixel data of each pixel, so that each pixel displays the correct color, however, the disadvantage of this method is that it requires a large memory space to store a huge amount of data

An image compensation method and an image compensation module are matched. The image compensation module is provided with a compensation storage unit and a reference storage unit. The image compensation method comprises the following steps of: inputting a target gray; acquiring a target current value which corresponds to the target gray from the compensation storage unit, wherein a gamma equation characteristic is present between the target gray and the target current value; acquiring a reference gray and a reference current value which corresponds to the reference gray from the reference storage unit, wherein the gamma equation characteristic is present between the reference gray and the reference current value; and acquiring a compensation gray according to the target current value, the reference gray and the reference current value.
Description
technical field [0001] The present invention relates to an image compensation module, a display panel, a display device and an image compensation method, in particular to an image compensation module, an OLED display panel, an OLED display device and an image compensation method. Background technique [0002] Organic Light Emitting Diode (OLED) has the advantages of self-illumination, high brightness, high contrast, light and thin size, low power consumption and fast response, and has been gradually applied to various display image systems, such as OLED display devices . OLED devices can be classified into passive matrix and active matrix according to their driving methods. However, the passive matrix type is limited by the driving mode, and has disadvantages such as short lifespan and inability to expand the area. Therefore, the active matrix type is more suitable for high-efficiency and large-size display applications. [0003] Active matrix organic light emitting displa...
