Abstract

The invention belongs to the technical field of graphic processing and relates to a display control method, a display control device, a computer readable medium and electronic equipment. The method comprises the following steps of: in response to a trigger operation, carrying out layer splitting on a target page to obtain layer information of the target page; creating a region list for the targetpage, and traversing the target page to add a target region in the target page into the region list; respectively comparing each target region in the region list with each layer, generating an updateregion on the basis of an intersection between the target region and the layer, and refreshing the region list according to the update region; and writing the update region into a cache for displayingthe target page containing the update region. According to the technical schemes, the requirement of a low-memory embedded device for high-resolution screen display can be met.

Description

technical field [0001] The present disclosure relates to the technical field of graphics processing, and in particular to a display control method, a display control device, a computer-readable medium, and an electronic device. Background technique [0002] As a free open source graphics library, LittlevGL is widely used in the design of embedded GUI (Graphical User Interface, Graphical User Interface). Generally speaking, the LittlevGL graphics library can support running on 16, 32 or 64-bit MCU processors, and the MCU clock frequency should be higher than 16MHz. And LittlevGL graphics library needs to configure the minimum memory, 64kB flash (display cache) is required for the basic control and the core code of LittlevGL graphics library, 16kB RAM is used for stack space, heap space for dynamically allocated memory, and buffer (buffer). However, for low-memory embedded devices, the LittlevGL graphics library shows that the main space occupied by the display frame buffer (...
