Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] In order to correctly output the data that the display device can receive and save time and resources, the present invention adopts a method of detecting the output data of the host to obtain the parameters of the display device. This method does not require software participation, and realizes self-adaptation for timing control of different display devices.

[0026] see figure 1 , is a structural block diagram of a preferred embodiment of a data conversion system in the present invention. The data conversion system includes a host 30 , a data conversion device 20 and a display device 40 .

[0027] The host 30 is an audio / video sending source device, such as a high-definition digital TV set-top box, a computer host, etc., which is used to transmit display data required by the display device 40 . The host 30 includes a LVDS (low voltage differential signal, ...

Abstract

The invention provides a data conversion device, a data conversion method and a data conversion system. The data conversion device comprises an LVDS data packet receiving module, an LVDS data packet transmitting module, a timing control data transmission branch circuit and a pixel data transmission branch circuit, wherein the timing control data transmission branch circuit transmits timing control data decomposed by the LVDS data packet receiving module to the LVDS data packet transmitting module, and the pixel data transmission branch circuit transmits pixel data decomposed by the LVDS data packet receiving module to the LVDS data packet transmitting module. By using the LVDS data to detect EDID information corresponding to a display device, the data conversion device and method greatly save host resources and improve transmission efficiency.

Description

technical field [0001] The invention relates to a data conversion device, a data conversion method and a data conversion system, in particular to a data conversion device, a data conversion method and a data conversion system for a flat panel display. Background technique [0002] Extended display identification data (extended display identification data, EDID) is a standard format data proposed by VESA (video electronics standard association) about the confirmation and capability identification of the display device, which is stored in the dedicated EEROM memory in the display device, which includes receivable Field frequency range, manufacturer, production date, product serial number, product model, standard display mode and other parameters to facilitate the normal operation of the host and display device as required. For the flat panel display, the relevant information includes the manufacturer of the display device, supported data interfaces and resolutions, and the lik...
