Problems solved by technology

[0004] However, in the above two methods, when the liquid crystal display to be tested enters the measurement area, it must be accurately placed in the same position, and errors cannot be tolerated. In this way, the sensor can be at the same position for each measurement when measuring the liquid crystal display to be tested.

Embodiment Construction

[0015] In a nutshell, the method of the present invention is: first make the tested liquid crystal display produce a picture, this picture includes a plurality of vertical stripes, and then move the sensor to align the sensor to the junction of the vertical stripes, and then record the level of the sensor at this time coordinate. Then, make the liquid crystal display produce another picture, this picture includes a plurality of horizontal stripes, and then move the sensor to align the sensor at the junction of the horizontal stripes, and then record the vertical coordinate of the sensor at this time. The horizontal and vertical coordinates obtained above are the positioning coordinates of the sensor. Through calculation, all measured points can be located, so that the sensor can accurately measure the corresponding measured points on the liquid crystal display.

[0016] See figure 2 Suppose there are nine test points 11, 12, 13, 21, 22, 23, 31, 32, 33 on the liquid crystal displa...

Abstract

A coordinates positioning method for picture measurement is first to generate a picture by a generating device including multiple vertical strips then a sensor is moved alinging with the intersection of vertical strips to record the horizontal coordinates this sensor this time, then another picture is generated by the generation device including multiple horizontal strips, then moving the sensor to the place aligning with the intersection of horizontal strips then to record its vertical coordinates, then to carry out coordinates positioning of the sensor according to the horizontal and vertical coordinates, the picture generating device may be a liquid crystal display or a projector.

Description

Technical field [0001] The invention relates to a coordinate positioning method for screen measurement, in particular to a coordinate positioning method for liquid crystal display measurement. Background technique [0002] See figure 1 , Which displays the existing liquid crystal display (LCD) detection equipment, where an xy mobile platform 140 is placed next to the conveyor 120, and a sensor 130 is provided on the xy mobile platform 140. The xy mobile platform 140 can make the sensor 130 or Move in the y-axis direction. A lot of liquid crystal displays 110, 110',... to be tested are placed on the conveying table 120, and the conveying table 120 sequentially conveys each liquid crystal display 110, 110',... to the sensor 130 in the direction of arrow A to be tested, and manually Or automatically connect the tested liquid crystal display 110 to the computer 150, and the computer 150 provides a signal to the liquid crystal display 110 to display the test s...
