Abstract

The embodiment of the invention provides a display driver, a control method, a display control circuit system and electronic equipment, relates to the technical field of electronics and communication, and is used for reducing the probability of a screen lag phenomenon when a dynamic image is displayed and reducing the power consumption of a display screen in a command mode. A time sequence control unit of the display driver sends a first pulse of a split screen effect signal every first preset time T1. When the receiving and transmitting unit does not receive the N-th frame of display data in the preset time, the time sequence control unit sends second pulses of the S split screen effect signals, the second pulses of the S split screen effect signals are used for prolonging the duration of the N-th frame for second preset time T2, and the host is instructed to display the N-th frame of display data according to the S-th second pulse of the split screen effect signals, and the generated N-th frame of display data is outputted at the (N + 1)-th frame. And the processing unit receives the N-th frame of display data at the (N + 1)-th frame, and controls the display screen to display the N-th frame of image according to the Nth frame of display data.

Description

technical field [0001] The present application relates to the technical field of electronics and communication, and in particular to a display driver and a control method, a display control circuit system, and electronic equipment. Background technique [0002] In an electronic device with a display function, there are two modes for transmitting image data to a display screen in the electronic device: a video mode and a command mode. In the video mode, the display data can be transmitted to the display screen in real time according to the refresh rate timing of the display screen. In the command mode, the display data is stored in the buffer first, and then the display data is extracted from the buffer and transmitted to the display for display. In this way, the display data in the cache needs to be updated only when the display image needs to be changed. [0003] However, in the case of using the command mode, when the electronic device displays a complex dynamic image, t...
