Abstract

The invention provides a power supply board testing device. A power supply board is a power supply board of a three-dimensional display device and the power supply board testing device comprises a control unit, a detection unit and a fault determining unit, wherein the control unit is used for simulating a control signal transmitted from a main board of the three-dimensional display device to the power supply board and transmitting the simulated control signal to the power supply board; the detection unit is used for detecting the output power of the power supply plate after the power supply plate receives the control signal; and the fault determining unit is connected with the detection unit and is used for receiving a detection result of the detection unit and determining whether the power supply plate has fault or not according to the detection result. Correspondingly, the invention further provides a power supply board testing method. Through the technical scheme of the invention, the fault in the power supply board of the three-dimensional display device can be exactly judged so that the quality of the power supply board can be effectively improved.

Description

technical field [0001] The invention relates to the field of power board testing, in particular to a power board testing device and a power board testing method. Background technique [0002] With the development and popularization of 3D LCD TV technology, the power board of this type of TV has a 3D control circuit part to realize the 3D control function. By adjusting the brightness of the backlight of the LCD TV, the 3D picture of the LCD TV can achieve the best display. Effect. However, since there has been no good detection method to detect this part of the circuit, the quality level of this type of power board is poor, and the pass-through rate is low. [0003] Therefore, there is a need for a new power board testing technology, which can accurately determine whether there is a fault in the power board in the three-dimensional display device, so as to effectively improve the quality of such power boards. Contents of the invention [0004] The technical problem to be ...
