Abstract

The invention discloses a VR display device supporting DSC compression and a control method thereof. The device comprises two DP circuits; each DP circuit comprises a DP2MIPI bridging chip, an MIPI-to-LVDS bridging chip, an FPGA unit, an LVDS-to-MIPI bridging chip and a display panel which are sequentially connected; the DP2MIPI bridging chips are used for converting DP data into MIPI data and transmitting the MIPI data to the MIPI-to-LVDS bridging chips; the MIPI-to-LVDS bridging chips are used for converting the MIPI data into LVDS data and transmitting the LVDS data to the FPGA units; the FPGA units are used for compressing the LVDS data and outputting the compressed LVDS data to the LVDS-to-MIPI bridging chips; the LVDS-to-MIPI bridging chips are used for converting the compressed LVDSdata into second MIPI data and outputting the second MIPI data to the display panels. The purposes that one DP circuit can realize 4K2K@75Hz-120Hz output and the two DP circuits can realize 8K2K@75Hz-120Hz output are achieved.

Description

technical field [0001] The present application relates to the technical field of VR display, in particular, to a VR display device supporting DSC compression and a control method thereof. Background technique [0002] One of the most important factors affecting the immersion of head-mounted display devices is the resolution. Due to the magnification of optical lenses, if the display resolution is too low, there will be an obvious screen door effect. The higher the resolution, the smaller the screen door effect. [0003] Limited by the current industry development, the current mainstream DP source or HDMI source and the bandwidth of the MIPIDSI interface cannot support the rate of 8K@75-120Hz. In addition, for the current VR screen, the panel that can support 4K2K needs to support DSC Compression, and currently there is no mature DP-to-MIPI or HDMI-to-MIPI chip that supports 4K2K with DSC compression. [0004] Therefore, the related art cannot effectively overcome the proble...
