Description
Technical field
The invention belongs to the automatic detection field of liquid crystal display defect, specifically a kind of advertisement liquid crystal display defect
Automatic checkout system.
Background technique
Liquid crystal display is the display equipment of planar ultra-thin, it is made of a certain number of colored or monochrome pixels, is placed
In front of light source or reflecting surface.Liquid crystal display power consumption is very low, therefore is favored by engineer, suitable for using the electricity of battery
Sub- equipment.Its cardinal principle is to generate point, line, surface cooperation back fluorescent tube with electric current stimulation liquid crystal molecule to be constituted picture, liquid crystal
It is such a organic compound, under normal temperature conditions, shows the mobility of existing liquid, and has the optics of crystal respectively to different
Property, thus it is known as " liquid crystal ", under the influence of the external conditions such as electric field, magnetic field, temperature, stress, molecule is easy to happen to be arranged again
Column, make the various optical properties of liquid crystal change therewith, this anisotropy of liquid crystal and its molecules align vulnerable to extra electric field,
The control in magnetic field exactly utilizes the physical basis of this liquid crystal, i.e. " electro-optic effect " of liquid crystal, realizes light by electric signal tune
System, so that liquid crystal display device be made, under the effect of different current electric fields, liquid crystal molecule can do 90 degree of rules rotating arrangements, produce
The difference of raw light transmittance, generates the difference of light and shade so at power source ON/OFF, and principle controls each pixel according to this, can constitute
Required image.It is well known that the face that liquid crystal display is made of the lamp bead of numerous volume very littles, but when in liquid crystal display
Lamp bead display effect can be seriously affected when being damaged, more can even make the information of display that entanglement, while existing screen occur
Curtain detection system can not in real-time detection screen lamp bead operating condition, once lamp bead, which is damaged, can not also be accurately positioned, and
It also cannot achieve self adjustment when entanglement occurs for transient copy.
Summary of the invention
In order to make up for the deficiencies of the prior art, a kind of automatic detection system of advertisement liquid crystal display defect proposed by the present invention
System.Present invention is mainly used for solution available liquid crystal display screens cannot achieve self detection, can not carry out to the lamp bead of internal damage
