A frame rate switching method and electronic device are disclosed, relating to the field of terminal technology. The method includes: after the frame rate switching process begins, the SoC (System-on-a-Chip) acquires a frame rate buffer lock for the frame rate switching process, sets a frame rate switching flag to a first value, and releases the frame rate buffer lock. With the frame rate switching flag set to the first value, during the time interval during which the SoC transmits a first image to the display screen: the SoC modifies the transmission time of a second image; and the SoC sends a switching command to the display screen using the Display Serial Interface (DSI), the switching command indicating the frequency of image scanning. The SoC transmits the second image to the display screen according to the modified transmission time, and the display screen scans the second image according to the modified frequency. In this way, the modification of the transmission time and the control of the scanning frequency can be completed during the transmission of one frame of image data, avoiding screen flickering during frame rate switching and improving the display effect during frame rate switching.

A system for implementing an augmented reality (AR) / virtual reality (VR) display includes a hardware (HW) architecture that employs a system-on-chip (SoC) to compose and submit textures. The SoC composes and submits textures by using display serial interface (DSI) display lines to transmit the textures to a physical display. Software (SW) architecture includes a stack display architecture with an applications level using the surface rendered by applications, a display service level to compose superframes, provide an abstraction layer on top of a surface flinger (SL) application programming interface (API), and allow assignment of textures and metadata to different hardware planes, and a driver level. The system uses the surfaces or enhanced effects that are rendered by the applications or the compositor, depending on the type of the application, and computes the metadata related to the location or coordinates.

This application provides a method and system for optimizing the response time of an LCD display screen, relating to the field of LCD display screen response time optimization technology. By acquiring the operating environment information and user operation intent information of the LCD display screen, the current display context state information is determined. Based on this state information, a core compensation coefficient with a data size not exceeding 50 bytes is generated and sent to the driver IC via a display serial interface. The driver IC autonomously calculates the overdrive voltage compensation value according to the received core compensation coefficient and pre-stored basic compensation rules, and accordingly generates the driving voltage applied to the corresponding pixel electrodes of the LCD panel. This application, by sensing the operating environment and user intent in real time and transmitting the core compensation information to the driver IC for autonomous calculation, achieves dynamic and refined adjustment of the overdrive voltage, improving the response speed and display quality of the display screen under varying operating conditions.
