Embodiment Construction

[0035] Figure 6 It is a schematic structural diagram of an embodiment of the optical property detection system of the present invention.

[0036] Such as figure 1 Shown is a flowchart of an embodiment of the optical property detection method of the present invention, which includes the following steps:

[0037] Step 101, the optical property detection control device receives a test request sent by the user for testing the optical properties of the display device or backlight to be tested. The test request carries test parameters, and the test parameters include the size of the screen to be tested and the number of points. The display device can be a TV or a monitor.

[0038] Step 102, the optical property detection control device acquires the coordinates of the point to be measured corresponding to the detection parameters from the database, and controls the video signal generator in the optical detection device to input a video signal to the display device or backlight t...

Abstract

The invention discloses a method for detecting optical properties, a system thereof and apparatus for controlling the detection of optical properties, wherein the method for detecting the optical properties comprises the following steps: a detection request carrying detection parameters therein is received; the detection parameters comprise the size of a screen to be detected and the quantity of points to be detected; the coordinates of the points to be detected corresponding to the detection parameters are obtained in a database; a video signal generator is controlled to input a video signalto a displaying apparatus to be detected or a back light source; the displaying apparatus to be detected or the back light source is moved by a controlling motor, so as to cause chroma meters to moveto the coordinates of the points to be detected in sequence; the brightness value and the chromatic value of the screen to be detected are detected in the coordinates of the points to be detected; detected brightness value and chromatic value of each point to be detected are calculated and processed, so as to obtain the brightness parameters, the chromatic parameters and the color reductive parameters of the displaying apparatus to be detected or the back light source to be output, as well as to generate the color gamut images of the displaying apparatus to be detected or the back light source to be output. The method can be used for completely and automatically detecting the optical properties of flat panel televisions of various sizes, and has perfect extendibility.

Description

technical field [0001] The invention relates to optical property detection technology, in particular to an optical property detection method and system, and optical property detection control equipment. Background technique [0002] In order to know the performance parameters of flat-panel TVs and their backlight devices, optical testing equipment is usually used to test the optical properties of flat-panel TVs and their backlight devices, including parameters such as brightness, chromaticity, color spots, viewing angles, and contrast. With the increasing development of the flat-panel TV industry, flat-panel TVs are gradually developing in the direction of large size and ultra-thin, which puts forward higher and higher requirements for the test performance of optical testing equipment. A mature optical inspection equipment should include accurate optical measurement equipment, rich video signal sources, a measuring platform with convenient rotation and displacement control, ...
