Light emitting device and method for detecting part of detecting flat panel display detection unit

Abstract

The invention provides a light detecting device and method of the detecting part of the flat panel display detection unit, used to detect the lighting state of the flat panel display panel which is transmitted form the panel supporting part to the work platform. The light detecting device comprises: light detecting body with an opening which is a square plate; a first plate which is fixed at one side of the light detecting body; a second plate which is fixed movably at one side of the first plate adjacent to the light detecting body; at least a sub-plate which can detachably connect to the first plate and the second plate and connect to the opening center of the light detecting body based on the dimension of the flat panel display panel; probe plate which can detachably connect to the first plate, the second plate or the sub-plate most close to the center of the light detecting device opening, wherein a plurality of probe plate are installed therein; and the position setting device for aligning the alignment mark displayed on the flat panel display panel to the actual reference mask to set the reference coordinate value.

Description

technical field [0001] The present invention relates to a luminescence test device and a luminescence test method of a test portion of a flat panel display test unit. Background technique [0002] It is well known to use glass substrates in the manufacture of flat panel displays such as thin film transistor liquid crystal displays (TFT-LCDs), plasma display panels (PDPs) and organic light emitting displays (OLEDs). In recent years, there has been a trend toward larger and thinner glass substrates (for example, 1,100 mm long, 1,250 mm wide, and 0.5-1 mm thick). Flat panel displays manufactured using glass substrates require luminescence testing during the final manufacturing process. In order to realize the luminescence test, it is necessary to perform an open circuit test and a color test on each data line and each gate line (gate line) of the flat panel display using a probe. In addition, visual inspection using a microscope or the like is also necessary. [0003] figur...

Problems solved by technology

[0019] In addition, whenever the imaging device 70 is repaired or replaced, the difficult task of resetting the position of the imaging device 70 is required.

Since the photographing device 70 is fixedly installed on the top surface of the substrate 30, it is difficult to apply the photographing device 70 to flat panel display panels 60 of various sizes.
