Title
(EN) COMPENSATION METHOD AND COMPENSATION DEVICE FOR VR DISPLAY AND DISPLAY DEVICE
Abstract
(EN)

A compensation method for VR display, a compensation device for VR display, and a display device are provided. The compensation method for VR display includes: calculating a first synchronization signal value to be output 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 frames of original image data in a case where a comparison result shows that the first synchronization signal value is greater than the second synchronization signal value; and compensating an image to be displayed according to generated compensation image data.
