Problems solved by technology

The control logic of the cmd mode is more complicated, and at the same time, the display screen is required to have a frame buffer, so the cost of executing the cmd mode is high, but its power consumption is low
[0005] However, for the same model of mobile phone displays, either they are all set to video mode or cmd mode, and switching between the two display modes cannot be performed; although some models of mobile phone displays can support video mode and cmd mode at the same time , but due to production process problems, it is easy to cause one of the modes to not work properly, because the switch between the two display modes cannot be performed, so that the entire display screen must be scrapped, thereby increasing the production cost

Embodiment 1

[0053] figure 1 The first implementation flow of the method for dynamically switching the display mode of the display screen provided by Embodiment 1 of the present invention is shown. For the convenience of description, only the parts related to this amplifier are shown.

[0054] In this embodiment, the method is applied to a display screen that simultaneously supports multiple display modes, and the display screen is a display screen of a smart terminal, and the smart terminal may be a mobile phone, an ipad, a computer, and the like.

[0055] Such as figure 1 As shown, the method includes:

[0056] In step S101, the display screen is initialized in the microkernel LK.

[0057] In this embodiment, the display mode switching of the display screen is performed during the start-up process of the display screen. During the startup process of the display screen, the display screen should be initialized in the microkernel LK at first. The initialization includes powering on and...

Abstract

The invention belongs to the technical field of display screens and provides a method and device for dynamically switching display modes of a display screen. According to the method and the device, a zone bit is additionally arranged in the display screen supporting a video mode and a command mode and used as the identification for switching the video mode and the command mode. In the starting process of the display screen, at first, the display screen is initialized in a microkernel LK; after initialization of the display screen is finished, the identification of the display screen is read; finally, the corresponding display mode is executed according to the zone bit. Accordingly, the display modes of the display screen are dynamically switched by reading the identification so that the display screen of the same type can be switched into another display mode when one mode is damaged, and can be utilized reasonably; moreover, the production cost of the display screen is lowered.

Description

technical field [0001] The invention belongs to the technical field of display screens, and in particular relates to a method and a device for dynamically switching display modes of a display screen. Background technique [0002] The display mode of the display screen of the existing mobile phone is generally a video mode and a cmd mode. [0003] The corresponding Chinese name of the video mode is video mode. In this mode, the mobile phone does not need to use a dedicated data signal to transmit synchronization information. The control signal and RGB data are directly transmitted through the MIPI bus in the form of a message, which requires the mobile phone CPU to continuously transmit refresh data to the display. The control logic of the video mode is simple and the cost is low, but the power consumption is relatively large. [0004] The corresponding Chinese name of the cmd mode is command mode. In this mode, the MIPI bus controller uses display command messages to send...
