Embodiment Construction

[0021] Embodiments of the method and system for detecting performance parameters of a display device according to the present invention will be described below with reference to the accompanying drawings.

[0022] figure 1 It is a flow chart of the performance parameter detection method of the display device of the present invention. Such as figure 1 As shown, the performance parameter detection method of the display device may include the following steps:

[0023] S1. Obtain the currently output first video sequence from the video sequence whose signal strength output by the display device is a preset value;

[0024] In this step, the video sequence may be a video sequence with higher quality, where the higher quality may refer to the signal strength corresponding to no mosaic effect after being decoded and output by the display device. The video signal generation device can be adjusted by the control device to output a video signal with higher quality to the display devic...

Abstract

The invention relates to a display device performance parameter detection method and system. The method comprises the following steps: a first video sequence which is currently output is obtained from video sequences, output from a display device, of which the signal strength is a preset value; the first video sequence is subjected to aligning operation according to pre-stored test sequences; the signal strength of the aligned first video sequence is adjusted to a first signal strength; the first signal strength is a threshold signal strength, between a non-triggering strength for mosaic effect and a mosaic effect triggering strength, of the aligned first video sequence after the aligned first video sequence is output via the display device; performance parameters of the display device are determined according to the first signal strength. The display device performance parameter detection method and system can realize automatic detection of the performance parameters, manual adjustment is not needed, no extra hardware device is required, and low cost and high efficiency can be achieved.

Description

technical field [0001] The invention relates to the technical field of signal detection, in particular to a method and system for detecting performance parameters of a display device. Background technique [0002] A display device is a device that can output images or tactile information. If the input signal is an electronic signal, this display device will be called an electronic display device, as opposed to a mechanical display device. Common display devices include televisions, computers, and the like. In order to ensure the normal operation of the display device, it is usually necessary to detect some performance parameters of the display device. Taking a TV as an example, the sensitivity of the main board of the TV is an important performance parameter of the TV. [0003] The existing scheme for detecting the sensitivity of the mainboard of a TV set is: send a video signal through a special device, output it to the mainboard of the TV set, and then display it on the...
