Problems solved by technology

Although there is currently an LVDS (Low-Voltage Differential Signaling) acquisition card developed by an American company that can assist testing, the acquisition card has a single function and cannot be used as a general-purpose screen at the same time, and its price is very expensive, which affects its use in LCD TVs. Promotion in the field of computer testing
In addition, there are many types of LCD motherboards, and different LCD motherboards use different screens. In the PCBA (Printed Circuit Board Assembly, printed circuit board assembly) test, the existing testing technology can only replace the corresponding specifications of the screen for different motherboards. Poor compatibility and low test efficiency

Abstract

The invention provides a television testing method, device and system. The method comprises the following steps: receiving an LVDS (low-voltage differential signal) output by a mainboard to be tested, and converting the LVDS into TTL (Transistor-transistor logic) level to be output; receiving the TTL level, programming according to the information contained in the TTL level, and outputting test data of a general screen; and receiving the test data of the general screen, and converting the test data of the general screen into an LVDS format to be output to the general screen to be used. The invention also provides the television testing device and the television testing system. The television testing method and the television testing device or the television testing system provided by the invention, can reduce the testing cost and improve the testing efficiency.

Description

Technical field [0001] The invention belongs to the technical field of TV testing, and relates to a TV testing method, device and system, and in particular to a testing method, device and system of an LCD TV motherboard that can reduce testing costs and improve testing efficiency. Background technique [0002] At present, the production testing of LCD (Liquid Crystal Display) televisions by several major domestic TV manufacturers is basically at the stage of traditional manual viewing testing. Although there is currently an LVDS (Low-Voltage Differential Signaling) capture card developed by a US company that can assist in testing, the capture card has a single function and cannot be used as a general-purpose screen at the same time, and its price is very expensive, which affects its use in LCD TVs. Promotion of machine testing field. In addition, there are many types of LCD motherboards, and different LCD motherboards use different screens. In the PCBA (Printed Circuit Board Ass...
