Abstract

The embodiment of the invention provides an image display method and device based on a Linux television. The method comprises the steps of determining the number of windows needing to be displayed onat least one first layer, wherein the at least one first layer is used for displaying the windows except the window corresponding to a system menu; determining no-refresh duration of a second layer, wherein the second layer is used for displaying the window corresponding to the system menu; determining to-be-displayed layers in the at least one first layer and the second layer according to the number of the windows needing to be displayed on the at least one first layer and the no-refresh duration of the second layer; and displaying the to-be-displayed layers on the television. The method andthe device are used for improving an image display effect of the Linux television.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of Linux TV, and in particular to an image display method and device based on Linux TV. Background technique [0002] Linux TV refers to the TV of Linux embedded system. The hardware capability of Linux TV is usually poor. Low and with a low number of cores. [0003] There are multiple preset layers in Linux TV, and each layer is used to display different types of windows. In the process of displaying images on Linux TV, according to the Z order of each layer, superimpose the extra layers to obtain the image to be displayed, and display the superimposed image on the TV. However, due to the limited hardware capabilities of Linux TV, it takes a lot of resources to superimpose all the layers, especially when displaying complex UI scenes, which will cause the picture displayed by Linux TV to freeze, resulting in the failure of Linux TV. Image display is poor. Contents of the invent...
