Problems solved by technology

Although this system can perform fully automatic testing and programming in the production of liquid crystal displays to improve production efficiency and product quality, it is a sequential testing process because the testing items such as power and image quality are independent of each other, so a lot of waste is wasted. The detection time affects the improvement of detection efficiency

Embodiment Construction

[0013] The liquid crystal display image quality and power two-in-one detection method of the present invention, such as figure 1 As shown, use the computer software system to make the computer, signal generator and power tester work together, and carry out the two-in-one detection of the image quality and power of the LCD display according to the following steps:

[0014] Step 1: connecting the signal generator and the power tester with the computer through the computer serial port, and simultaneously connecting the liquid crystal display to be tested with the signal generator and the power tester;

[0015] Step 2: The signal generator automatically sends the first detection picture signal to the liquid crystal display to detect the first detection picture;

[0016] Step 3: After the computer receives the trigger command that the detection of the previous detection picture is completed, the computer controls the signal generator to send the next detection picture signal to the...

Abstract

The invention relates to the field of LCD (liquid crystal display) detection technology, and in particular relates to a two-in-one detection method of picture quality and power of an LCD. The method is characterized in that the two-in-one detection of the picture quality and the power of the LCD is performed by the following steps with the cooperation of a computer, a signal generator and a powertester: 1, connecting the LCD; 2, automatically sending a first detection picture signal to the LCD so as to detect a first detection picture; 3, sending the next detection picture signal to the LCD so as to detect the next detection picture; 4, repeating the step 3 until all detection pictures except white pictures are detected; 5, sending a white picture signal to the LCD so as to detect the white pictures; meanwhile, testing the power of the LCD, and if power test data complies with specification, indicating that the power test is passed, otherwise carrying out exception handling; and 6, disconnecting the LCD and finishing the detection. The method is beneficial to saving of the detection time and improving of the working efficiency.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display detection, in particular to a liquid crystal display image quality and power two-in-one detection method. Background technique [0002] In the prior art, liquid crystal displays need to be inspected on multiple items such as power, image quality, and safety regulations on the production line. At present, since each testing item is carried out independently, a lot of testing time is wasted and production efficiency is reduced. The application number is [201010301148.0], which discloses a system and method for automatically testing the power of display equipment on a production line. The method uses the cooperation of communication cards, main control computers, power meters and PLC controllers installed on the production line to measure the power of display equipment. automatic testing. Although the system and method can save labor, improve the degree of automation, and improve pro...
