Problems solved by technology

First, because it takes a long time to age the display panels 10 after emitting light, even if they have moved to the detection position, it is difficult to continuously detect the display panels 10, so that the detection efficiency cannot be improved
Second, although many display panels 10 are detected at one time, the detection height and width are very large, so that the inspector cannot detect the display panels 10 from various angles
Third, in order to inspect more display panels 10, the number of workbenches required increases, thereby wasting work time control and space
Fourth, because many display panels 10 are inspected at one time, the backlight unit (not shown) and workbenches 212 and 214 (flat panels that move left and right) increase in size, thereby making the inspection device larger
Fifth, since the display panel 10 is provided and sorted while the display panel 10 is aged after emitting light, it is difficult to continuously detect the display panel 10, so that the detection efficiency cannot be improved

Embodiment Construction

[0019] The present invention will be explained in more detail below in conjunction with the accompanying drawings. Like reference numerals refer to like elements throughout.

[0020] figure 2 and image 3 They are a front view and a top view of the rotating display panel inspection device 100 of the present invention, respectively. The inspection device 100 is a microscope inspection device that performs an opening test and a color test for each data line and each gate line of a small-sized inspection target (hereinafter referred to as "display panel 10") requiring burn-in by means of a probe unit . The testing device 100 continuously tests the small-sized display panel 10 to improve productivity. Therefore, the detection device 100 is configured to be able to rotate the detection unit 120 that detects the display panel 10 .

[0021] The detection device 100 includes a base 102 , a turntable 110 and four detection units 120 .

[0022] The turntable is rotatably mounted ...

Abstract

The invention relates to rotary measuring device for display board, comprising rotary table installed on chassis and measuring unit installed on said rotary table for measuring display board. The rotary table rotates with regular angle and said measuring units are mounted around rotary axis of rotary table with their regular angle. The display board can be measured continuously by using said device, so the productivity is improved.

Description

[0001] Cross References to Related Applications [0001] This patent application claims priority from Korean Patent Application 2005-47333 filed on Jun. 2, 2005, the entire contents of which are hereby incorporated by reference. technical field [0002] The invention relates to a rotating display panel testing device and a display panel testing method using the testing device. More specifically, the present invention relates to a rotary type display panel inspection device for continuously performing a luminescence test on a small-sized display panel requiring aging, and to a display panel inspection method using the inspection device . Background technique [0003] Generally, most of the flat panel display products are thin film transistor liquid crystal displays (TFT-LCD), which tend to be large-sized and high-resolution due to the innovation of production technology and the results of research and development (R&D). Since the application of TFT-LCDs not only involves no...
