Title
(EN) VR display compensation method and device and display system
(ZH) VR显示的补偿方法及补偿装置、显示系统
Abstract
(EN)
The invention provides a VR display compensation method and device and a display system, and belongs to the technical field of display. The method includes the steps: calculating a first synchronization signal value outputted by a controller according to a rendering resolution, a rendering frame rate and bandwidth data of a display panel; comparing the first synchronization signal value with a pre-stored second synchronization signal value of the display panel; generating compensation image data between two adjacent frame original image data when the first synchronization signal value is greater than the second synchronization signal value through comparison; and compensating for the to-be-displayed image according to the generated compensated image data.
