Specific embodiment
The explanation of following embodiment is refer to the attached drawing, can be to the specific embodiment implemented to the example present invention.
It please referring to shown in Fig. 1, the embodiment of the present invention one provides a kind of panel lighting test system, including:
Panel lighting machine 1, for placing detection panel 11 and providing backlight for the detection panel 11 in lighting test;
Lighting machine control device 2 obtains the detection panel 11 from factory system for the ID according to the detection panel 11 and exists Repairing location information in processing procedure, and the repairing location information is sent to projection arrangement 4;
Signal generator 3 is electrically connected respectively with the lighting machine control device 2 and the detection panel 11, for generating lighting Test signal controls the detection panel 11 to show respective picture;
Projection arrangement 4 is electrically connected with the lighting machine control device 2, for according to the repairing location information, will repair position A is projected in the detection panel 11.
The present embodiment increases projection arrangement in panel lighting test system, by repairing position of the detection panel in processing procedure Project in the detection panel, convenient for after detection panel is lighted testing staff accurately know detection panel in processing procedure Position is repaired, so as to pointedly go to pat or press, improves testing efficiency.
Specifically, detection panel 11, if be repaired due to appearance is bad, is being repaired location information and is being incited somebody to action during processing procedure It is stored into factory system 5(FAB System).Position is repaired usually by coordinate representation, such as some point is repaiied It mends, then the repairing position can be with coordinate representation(x0, y0);Such as certain line is repaired, then the repairing position can Using with the coordinate representations of two endpoints of line segment as(x1, y1),(x2, y2).In this way, according to the ID of detection panel 11, pass through lighting Machine control device 2 can inquire the repairing position embodied with aforementioned coordinate form of the acquisition detection panel 11 in factory system 5 Information.
Incorporated by reference to shown in Fig. 2, projection arrangement 4 is electrically connected with lighting machine control device 2, and lighting machine control device 2 is in factory After the inquiry of system 5 obtains the repairing location information of detection panel 11, the repairing location information of detection panel 11 is sent to projection Device 4, projection arrangement 4 are projected position A is repaired in the detection panel 11 being positioned on panel lighting machine 1 with laser mode. Due to being same detection panel, the repairing position A in the detection panel 11 being positioned on panel lighting machine 1 is projected, It matches with repairing position of the detection panel in processing procedure, generating lighting test by signal generator 3 again at this time believes Number detection panel 11 is lighted, that is, detection panel 11 is controlled to show any picture such as white, red, green, blue, black, grayscale, testing staff R Can targetedly repairing position A be patted or be pressed, avoid the blindness operated in the past.
Projection arrangement 4 projects the laser that uses by for high bright green or highlighted red laser, certainly, to make repairing for projection Cover is put A and can clearly be presented in detection panel 11, and the laser color that projection arrangement 4 projects should be controlled with signal generator 3 The color for the picture that detection panel 11 processed is shown differs or color is identical but brightness is different.Further, lighting machine control Device 2 processed can increase zone identification information when sending repairing location information to projection arrangement 4, i.e., increase around repairing position The marks such as frame make projection arrangement 4 that will repair position A when projecting in detection panel 11, while area identification are projected On display panel 11 so that repairing position A can be irised out by marks such as frames, to repair position A more clearly in detection panel It is presented on 11, is further conducive to testing staff's observation.
As shown in figure 3, in the present embodiment, panel lighting machine 2 includes:Supporter 1;The workbench being arranged on supporter 1 10, for accommodating simultaneously fixed test panel 11;The backlight 12 at 10 rear of workbench is arranged on, for being inspection in lighting test It surveys panel 11 and backlight is provided.
Referring again to shown in Fig. 4, corresponding to the embodiment of the present invention one, the embodiment of the present invention two provides a kind of panel lighting and surveys Method for testing, including:
Lighting machine control device obtains the detection according to the ID for the detection panel being positioned on panel lighting machine from factory system Repairing location information of the panel in processing procedure, and the repairing location information is sent to projection arrangement;
The projection arrangement projects to repairing position in the detection panel according to the repairing location information;
Signal generator generates the detection panel display respective picture that the control of lighting test signal is projected repairing position.
Please with reference to shown in earlier figures 1, Fig. 2, projection arrangement 4 projects the laser that uses by for high bright green or highlighting Red laser, certainly, the repairing position A to enable projection are clearly presented in detection panel 11, what projection arrangement 4 projected The color of picture that laser color should control detection panel 11 to show with signal generator 3 differs or color is identical but bright Degree is different.Further, it can increase region mark when lighting machine control device 2 sends repairing location information to projection arrangement 4 Know information, i.e., increase the marks such as frame around repairing position, projection arrangement 4 is made to project detection panel 11 by position A is repaired When upper, while area identification being projected on display panel 11 so that repairing position A can be irised out by marks such as frames, so as to Repairing position A is more clearly presented in detection panel 11, is further conducive to testing staff's observation.
By above description it is found that the advantageous effect of the embodiment of the present invention is:By increasing projection arrangement, by detection faces Repairing position of the plate in processing procedure is projected in detection panel, convenient for after detection panel is lighted testing staff accurately know inspection Repairing position of the panel in processing procedure is surveyed, so as to pointedly go to pat or press, improves testing efficiency.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly It encloses, therefore equivalent variations made according to the claims of the present invention, is still within the scope of the present invention.
