Embodiment Construction

[0050] The phenomenon of moiré (Mura) is diverse and variable, and not all can be detected by a single viewing angle. The present invention uses one or more high-resolution charge-coupled device cameras (CCD Camera) or complementary metal-oxide-semiconductor (CMOS ) to capture and detect the display panel from multiple different angles, and its multi-angle measurement system includes (1) MURA image capture unit, which uses a multi-angle image capture mechanism to capture the moiré phenomenon; (2) MURA The image processing unit uses a MURA image processing program to perform MURA image analysis and MURA identification and classification processing, providing quantitative MURA detection technology; (3) the database unit is to establish a quality interactive processing analysis database to provide friendly interfaces and interactions query function.

[0051] Because the MURA phenomenon is diverse and variable, not all can be detected by a single viewing angle, so the main compone...

Abstract

A multi angle measuring system for a display comprises a MURA image capturing unit, a MURA image processing unit and a data base unit, using a multi angle image capturing mechanism to capture the MURA phenomenon of the display, with a MURA image processing program for image analysis and identification classification treatment, providing quantified MURA inspection, establishing quality interactive handling analytical database, to provide friendly interface and interactive inquiry function. Through oblique angle calibration to improve view depth optical structure and ladder infidelity program image restoring establishes a quality interactive process analytical database, to provide a measuring system for the application of production line in an objective and stable way.

Description

technical field [0001] A multi-angle measurement system and method for quantifying the MURA phenomenon on a display panel, in particular, a multi-angle imaging mechanism is used to capture images from multiple angles of view of the panel, and establish a database for quality interactive processing and analysis. Background technique [0002] With the widespread application of flat-panel displays, such as liquid crystal displays (LCDs), which are widely used in TVs, computer monitors, mobile phones, and various home appliances, the quality of LCD panels needs to be paid more and more attention under mass production, such as color, Contrast, response time, brightness, etc. Regarding the uniformity of the LCD background, observe the situation of moiré (MURA) caused by abnormal LCD luminance. MURA refers to the phenomenon of various traces caused by uneven brightness of the display. The display defects caused by attaching color filters, the driver chip (Drive IC), and the liquid ...
