Description
Technical field
The invention relates to a kind of display device patch system, and particularly relevant for the repair apparatus and the method thereof of a kind of pixel (Pixel) element.
Background technology
Pixel (pixel) is to form the least unit of LCD image (dot chart).The pattern of pixels of LCD is generally by being positioned at thin film transistor (TFT) (Thin Film Transistor; TFT) colored filter (the Color Filter between array base palte and the subtend substrate; CF) and thin film transistor (TFT) array or polymer LED (Polymer Light emitting Diode; PLED) array defines and forms.
Wherein colored filter, thin film transistor (TFT) array or polymer LED array all use the gold-tinted manufacturing to form.Making flow process with colored filter is an example, at first black resin is coated on the transparent base, uses the gold-tinted manufacturing to form black matrix" (Black Matrix) by exposure, development, inspection and baking back; Among black matrix", form redness, green or blue pattern more in the same way to constitute colored filter.Yet; because the error of light shield contraposition during gold-tinted is made; regular meeting makes the dot structure that is made of colored filter or thin film transistor (TFT) array produce defective; the electric field controls generation problem that causes thin film transistor (TFT) array; and influence display quality; and this problem more goes from bad to worse along with the lifting of image pixel density requirement, therefore must further repair dot structure.
Present repairing method, remove attached to the residuals for the treatment of on the patch area substrate surface with mode part radium-shine or that grind, directly attach red, green, blue or black repairing liquid with the syringe needle of repairing pin again, or to be pre-charged with the kapillary of repairing liquid, to repair liquid is built-up in and treats among the patch area, and carry out local irradiation, or toast to finish to repair by infrared ray again after the irradiation with ultraviolet light comprehensively and make by ultraviolet ray.
Yet, owing to attach or adopt kapillary to carry out the mode that pixel is repaired with syringe needle, the repair liquid volume that can provide each time is all fixing, when the repair liquid volume for the treatment of that the required repairing volume of patch area attaches greater than syringe needle or single kapillary can provide, just must attach repeatedly and repair liquid or change step capillaceous, not only influence the manufacturing progress, and make the board perseveration because of attaching repeatedly to repair liquid or change kapillary, also influence the bearing accuracy of repairing easily, and cause the repairing manufacturing failure.
Therefore having to provide that a kind of cost is lower, structure simple and operation is convenient, can take into account the display image pixel repair apparatus and the method thereof of repairing precision and quality.
Summary of the invention
One embodiment of the present of invention are that a kind of patch system that is used for the defect pixel element in the repairing display panel is being provided.This pixel element repairing system comprises: flaw locating module, optical checking module, defect removal module, ink spray module and ink droplet curing module.The flaw locating module is used for locating defect pixel element.Optical checking module is used for capturing the defective image of defect pixel element.Defect removal module removes defect pixel element according to the defective image, treats patch area to provide one.Ink spray module is used to provide a plurality of ink droplets, and it is attached to treat on the patch area.The ink droplet curing module is used for drying and is attached to the ink droplet for the treatment of on the patch area.Combination by above-mentioned module, can provide a kind of structure simple, and can continue to provide repairing liquid, the defective of pixel element can once be repaired to be finished, exempting known technology must repeatedly attach repairing liquid repeatedly or change step capillaceous, saving the number of times that repair apparatus moves back and forth and locatees, and then improve and repair manufacturing accuracy and yield rate.
An alternative embodiment of the invention is that a kind of method that is used for defect pixel element in the repairing display panel is being provided, can provide defect pixel and continue and disposable repairing, exempt known technology and must repeatedly attach repair liquid repeatedly or change step capillaceous, improve and repair manufacturing accuracy and yield rate.The pixel element repairing method comprises the steps:
At first adopt optical checking module to capture a plurality of pixel element images in this display panel.Then define at least one defect pixel element according to these pixel element images, and the defective image of acquisition defective element.Adopt the flaw locating module to locate defect pixel element again.According to the defective image, adopt defect removal module to remove defect pixel element then, treat patch area so that at least one to be provided.Adopt ink spray module that a plurality of ink droplets are provided then, and it is attached to treat on the patch area.Following adopted ink droplet curing module is dried and is attached to the ink droplet for the treatment of on the patch area.
