Embodiment Construction

[0024] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for ease of description, only parts related to the invention are shown in the drawings.

[0025] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] It can be understood that in the field of display technology, in order to display medium and large sizes, it is necessary to drive the display panel through multiple driver chips (Source ICs). For example, ordinary mobile phone products only need a Source IC to realize the drive. For large...

Abstract

The invention discloses a display module and a display device, the display module comprises a display panel, a master driving chip and at least one slave driving chip, and the slave driving chip is communicated with the master driving chip; and the master driving chip is used for transmitting a plurality of binding point voltage values to the slave driving chip, and the binding voltage values aredetermined by optical data of the display panel acquired by the master driving chip. According to the embodiment of the invention, the master driving chip is used for transmitting the precise bindingvoltages determined through the optical data of the master driving chip to the slave drive chip, the slave driving chips can lock the binding points by utilizing the obtained accurate binding voltagevalues, so that all the driving chips in the display module output consistent gamma voltages, split-screen display caused by the difference of the gamma voltages of different driving chips is avoided,and the display quality is improved.

Description

technical field [0001] The present invention generally relates to the field of display technology, and in particular to a display module and a display device. Background technique [0002] With the continuous development of display technology, as a new generation of display technology, OLED products have become a Mainstream high-end products pursued by customers. While OLED display modules have been widely used in small-sized products such as mobile phones, the demand for large-sized products is also increasing. [0003] For large-sized display modules, due to the increase of driver chips (source ICs), and the differences in the characteristics of each driver chip, it is easy to cause a split-screen phenomenon during the display process, resulting in poor display effects and poor user experience. Contents of the invention [0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a display module and a display panel, by usi...
