Embodiment Construction

[0022] Hereinafter, preferred embodiments of the optical detection device and the array testing device with the optical detection device according to the present invention will be described in detail with reference to the accompanying drawings.

[0023] The array testing device according to the present invention includes a base frame 10, a loading unit 30 for loading a glass panel P, a testing unit 20 for testing the glass panel P loaded by the loading unit 30, and a glass panel P that has been tested by the testing unit 20 from the loading unit 30. Unit 30 unloads unit 40 unloaded.

[0024] The testing unit 20 tests the glass panel P for electrical defects. The testing unit 20 includes a light-transmitting support 21 , a testing module 22 , a probe assembly 23 and a control unit (not shown). The glass panel P loaded by the loading unit 30 is placed on the light-transmitting support 21 . The testing module 22 tests electrical defects of the glass panel P placed on the light-...

Abstract

The invention discloses an optical detecting device and an array test device possessing the same. By using the optical detecting device and the array test device possessing the same of the invention, a structure used for adjusting an optical system magnifying power can be simplified, and the generation of external impurities can be prevented when the optical system magnifying power is adjusted, thereby preventing the external impurities from polluting an optical system or a glass panel.

Description

technical field [0001] The invention relates to an optical detection device for testing and measuring glass panels, and an array testing device with the optical detection device. Background technique [0002] In general, a flat panel display (FPD) is an image display device that is lighter and thinner than a television or monitor having a Braun Tube. Liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), and organic light emitting diodes (OLEDs) are representative examples of flat panel displays that have been developed and used. [0003] The LCD in these FPDs is an image display that displays a desired image by individually supplying a data signal based on image information to liquid crystal cells arranged in a matrix shape to control light transmittance of the liquid crystal cells. LCDs are thin and light, and have many other advantages including low power consumption and low operating voltage, and thus are widely used. In the manuf...
