Abstract

The invention provides a DVI (digital visual interface) signal conversion apparatus and a DVI signal input test board. The DVI signal conversion apparatus comprises a TTL (transistor-transistor level) signal conversion unit, an LVDS (low-voltage differential signaling) signal conversion unit and an electrostatic discharge protection unit, wherein the TTL signal conversion unit is used for converting a DVI signal into a TTL signal; the LVDS signal conversion unit is used for converting the TTL signal into an LVDS signal; the electrostatic discharge protection unit is used for carrying out the electrostatic discharge protection for the LVDS signal. The DVI signal can be converted into the LVDS signal and the TTL signal, no software is used for processing the signals, all data are processed by hardware, so that the completeness of the signals can be maximally guaranteed, and the DVI signal conversion apparatus can be used as a debugging board to debug the relevant optical indexes of a test screen.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a DVI (Digital Visual Interface, digital video interface) signal conversion device and a DVI signal input test board. Background technique [0002] At present, in the development process of LCD screens, especially in the development process of small and medium-sized LCD screens, a set of lighting equipment is required, and a corresponding method for converting DVI signals into LVDS (Low-Voltage Differential Signaling, low-voltage differential signal) signals is required. and TTL (Transistor-Transistor Logic Level) signals. [0003] However, the existing DVI signal input test boards cannot fully process data with hardware, so that the integrity of the signal cannot be guaranteed to the greatest extent, and the signal needs to be processed through software, which cannot meet the requirements, especially for many heterogeneities in the development process. Screens and special reso...
