Problems solved by technology

However, the hardware structure of the commonly used mini-LVDS transmission interface is completely different from that of the PPDS transmission interface, so that the transmission of configuration information cannot be realized in the mini-LVDS transmission interface.

Abstract

The invention provides a driving device of a display panel, a display device, and an operating method thereof. The driving device is composed of a time sequence controller and a plurality of source drivers. The time sequence controller is used for outputting display data and configuration information. Each source drive is coupled to the time sequence controller through a first interface and a second interface. The time sequence controller transmits the display data to the source driver through the first interface and transmits the configuration information to the source driver through the second interface. The first interfaces are different from the second interfaces.

Description

technical field [0001] The invention relates to a display driving technology, and in particular to a display panel driving device and an operating method for transmitting configuration information between a timing controller and a source driver. Background technique [0002] Currently, timing controllers and source drivers on flat panel displays (such as thin film transistor-liquid crystal displays (TFT-LCDs)) have various interfaces that can be used to transmit image display data. One of these interfaces is selected for data transfer between the timing controller and the source driver. These interfaces are, for example, miniature serial low voltage differential signaling (Mini Low Voltage Differential Signaling; mini-LVDS) transmission interfaces. [0003] Due to the increasing number of picture resolutions and liquid crystal pixel configurations used in displays, the timing controller gradually needs to transmit additional configuration information to control and / or adjus...
