Abstract

The invention discloses an interface converting circuit, a display panel driving method and a display device which are used for achieving the purpose of UHD image display through at least one LVDS interface combined with the UHD display device. The interface converting circuit comprises the LVDS interface and a data format conversion module. The LVDS interface is used for receiving LVDS signals from an LVDS signal source, and sending the LVDS signals to the data format conversion module. The data format conversion module is used for converting the received LVDS signals into eDP signals of a digital video interface.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an interface conversion circuit, a display panel driving method and a display device. Background technique [0002] With the development of display technology, the resolution of the display panel is getting higher and higher. The resolution does not exceed 1280*720 SD (Standard Definition) display, which can no longer meet the needs of some consumers. Full High Definition (Full High Definition, FHD) displays have begun to become popular, and Ultra High Definition (Ultra High Definition, UHD) has also gradually poured into the market, becoming a goal pursued by people. [0003] Existing technology In terms of internal interfaces, when the traditional low-voltage differential signal (LVDS) interface is applied to a high-resolution UHD display panel, it requires a large number of channels and complex design, and the traditional system with LVDS output interface is not compatible w...
