System and method for detecting surface oxidation of liquid crystal display

Abstract

The invention discloses a system and method for detecting surface oxidation of a liquid crystal display. The system comprises a color code sensor, a first position sensor and a first processor, both the color code sensor and the first position sensor is connected with the first processor, the first position sensor is used for detecting whether a target liquid crystal display reaches a first preset detection position or not and outputting a first position signal toward the first processor if the target liquid crystal display reaches the first preset detection position; the color code sensor is used for detecting in real time whether a color difference exists between color of the surface of the target liquid crystal display and color of the surface of a standard liquid crystal display or not and outputting a first color difference detection signal containing a detection result; the first processor is used for reading a first current color difference detection signal outputted by the color code sensor after the first position signal is received and determining surface oxidation detection results of the target liquid crystal display according to the first current color difference detection signal. Surface oxidation of the liquid crystal display is more simply and rapidly detected by the system.

Description

technical field [0001] The invention relates to the technical field of surface defect detection, in particular to a system and method for detecting surface oxidation of a liquid crystal screen. Background technique [0002] In the manufacturing process of LCD screens, due to the cumbersome process, some situations that affect the quality of LCD screens often occur, for example, uneven distribution of liquid crystal materials in the panel for making LCD screens, or distortion of the filter in the backlight plate And other phenomena, the occurrence of these phenomena will lead to defects on the surface of the produced LCD screen, such as large areas of dirt on the surface, pinholes or scratches on the surface, etc. Once surface defects appear, the use effect of the LCD screen will be affected. Therefore, LCD screens with surface defects need to be selected as unqualified products during production. [0003] The surface chromatic aberration defect of the LCD screen is one of t...
