Problems solved by technology

This may cause conflicts between applications implemented based on DirectFB and applications implemented based on OpenGL ES when displaying
For example, when there are two device data (DirectFB device and OpenGL ES device) output to the display device at the same time, display confusion will occur

Abstract

The invention discloses a human-machine interface display processing device and method. The human-machine interface display processing device is applied to embedded equipment. A first application and a second application can be simultaneously installed in the embedded equipment. The device comprises first graph drawing equipment, second graph drawing equipment and rendering equipment. The first graph drawing equipment is used for drawing data needing to be displayed by the first application in a first graph cache. The second graph drawing equipment is used for drawing data needing to be displayed by the second application in a second graph cache. The rendering equipment is used for synthesizing the corresponding data of the first graph cache and the second graph cache to form an effective image and rendering the effective image in display equipment for display. It can be achieved that interfaces of the two applications based on different graph drawing engines in the embedded equipment are simultaneously displayed on the display equipment.

Description

technical field [0001] The present disclosure relates to embedded device technology, in particular to a display processing device and method for a human-machine interface. Background technique [0002] With the continuous improvement of hardware technology, most smart devices already support OpenGL ES graphics acceleration devices to quickly display complex 2D / 3D graphics. [0003] In a software system of an embedded device, it is possible to integrate various application programs such as application programs provided by a third party and some application programs provided by the smart device. The man-machine interface of some of these application programs may be realized based on the DirectFB technology, while the man-machine interface of another part of the application programs may be realized based on the OpenGL ES technology. This may cause conflicts between applications implemented based on DirectFB and applications implemented based on OpenGL ES when displayed. For e...
