Problems solved by technology
After the display screen has been used for a long time, the driver chip in the display device cannot meet the needs of the display device; on the other hand, it takes more than a year for a chip to go from design to stable production. Cannot meet the needs of new display devices, cannot adapt to the needs of display devices; thus shortening the life cycle of chips

Embodiment Construction
[0021] As mentioned in the background technology, the technical problem of the short life cycle of the driver chip in the prior art, the inventor found that the reason for this problem is that the OLED device is inevitably aging after a long period of use of the display screen, resulting in Overall brightness drops, long-term image retention, and display color cast. Pixels at different positions in the same display screen have different degrees of aging, resulting in afterimages on the screen. The longer the use of pixels with higher brightness, the more serious the aging of the device, so it is necessary to compensate for the display, but the driver chip originally used in the display device cannot compensate for the defects of the display device at this time; on the other hand, a chip from design to stable production It takes more than one year. With the development of display technology, newly manufactured chips may not be able to meet the needs of new display devices, and ...

The invention provides a driving chip, and solves the technical problem of short life cycle of a driving chip in the prior art. The embodiment of the invention provides a driving chip. The chip comprises a plurality of compensation modules connected in parallel. A compensation algorithm is stored in each compensation module. When characteristics of the display device change, the driving chip acquires data of characteristic change, selects a matched compensation algorithm according to the data of characteristic change, and then compensates the display of the display device through the corresponding compensation algorithm, so that the display device emits light normally. Therefore, according to the embodiment of the invention, multiple compensation algorithms are set. When a display in the display device ages or the display device is updated, a corresponding compensation method can be found in a plurality of compensation algorithms, so that the compensation method can be matched with thedisplay device under the condition that the chip is not revised, and the life cycle of the driving chip is prolonged.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a driving chip and a display device. Background technique [0002] OLED display screens in the prior art use organic materials to make light-emitting devices, and the devices flow relatively large currents. After the display screen has been used for a long time, the driver chip in the display device cannot meet the needs of the display device; on the other hand, it takes more than a year for a chip to go from design to stable production. The requirements of new display devices cannot be met, and the requirements of display devices cannot be adapted; therefore, the life cycle of chips is shortened. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a driving chip and a display device, which solve the technical problem of a short chip life cycle in the prior art. [0004] In order to make the purpose, technical means and advanta...
