Abstract

The invention discloses an OLED (Organic Light Emitting Diode) panel display defect restoration method. The method comprises the following steps that when the OLED panel display defect restoration is required, firstly, an OLED panel is fixed on a vacuum absorption platform through vacuum; then, the OLED panel is lightened through a light-up system, at this moment, an approximate position of a repairable display defect can be determined by the lightened OLED panel, and the display defect is labeled; an adjustable platform of a display defect detection device is adjusted to move a microscope at a position above the display defect labeled in the previous step, the microscope is adjusted for accurately positioning the display defect, and image information of the display defect can be obtained through a display device; and a laser generator is opened, and under the real-time monitor and guidance of the display device, an emitted laser beam is utilized to display and accurately restore the defect.

Description

Oled panel display defect restorative procedure
Technical field
The invention belongs to OLED display technique field, be specifically related to a kind of oled panel display defect restorative procedure.
Background technology
Oled panel, after completing aging processing procedure, needs to carry out check mark to its display display defect, and repairs recoverable display defect.Inspection restorative procedure conventional is at present: first, artificial hand-held microscope carries out display defect inspection; Then, display defect part is indicated; 3rd step, is transferred to the substrate indicated on laser repairing platform and again locates display defect part; 4th step, carries out laser repairing to display defect part.Although this inspection restorative procedure is simple to operate, there are some obvious display defects simultaneously, on the one hand, to the resetting of display defect part, affect the inspection remediation efficiency of oled panel display defect in easy left-hand seat and being used widely; On the other hand, the accuracy rate of resetting relies on artifact, higher and have impact on the product yield of oled panel artificially to the requirement of operating personnel.
Summary of the invention
The object of the invention is to the problems referred to above overcoming prior art existence, provide a kind of inspection remediation efficiency high and oled panel display defect restorative procedure accurately can be repaired.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of oled panel display defect restorative procedure, is characterized in that, comprises the steps:, when needs carry out the reparation of oled panel display defect, first, to be fixed on vacuum absorbing platform by oled panel vacuum; Then, with lighting system, oled panel is lighted, now, by the oled substrate lighted, the approximate location of the display defect of recoverability can be determined, and display defect is marked; 3rd step, directly over regulate the adjustable platform of display defect testing fixture that microscope is moved to display defect that previous step marks, regulates microscope accurately to locate display defect, and obtains the image information of display defect by display device; 4th step, opens laser generator, in the real-time monitoring of display device with under instructing, utilizes the laser beam of launching precisely to repair display defect.
Compared with prior art, the invention has the beneficial effects as follows: oled panel display defect restorative procedure of the present invention is by overlapping with the microscope camera lens of display defect testing fixture by the laser head of laser generator, avoid the resetting to oled panel display defect, after display defect is checked through, can directly repair without the need to mobile oled panel, not only improve remediation efficiency, improve the accuracy rate of the reparation of oled panel display defect simultaneously.
Accompanying drawing explanation
Fig. 1 shows the structural representation for oled panel display defect restorative procedure of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, oled panel display defect restorative procedure in the present embodiment comprises vacuum absorbing platform 1, lighting system 2, display defect testing fixture 3 and laser generator 4, wherein, display defect testing fixture 3 comprises display device 31, microscope 32, CCD and adjustable platform, and microscope 32 to be fixed in adjustable platform and to be shown in display device 31 by CCD by image; The laser head of laser generator 4 is overlapping with microscope 32 camera lens of display defect testing fixture 3, and when oled panel display defect is repaired, microscope 32 is positioned at directly over vacuum absorbing platform 1.
When needs carry out the reparation of oled panel display defect, first, oled panel vacuum is fixed on vacuum absorbing platform 1; Then, with lighting system 2, oled panel is lighted, now, by the oled substrate lighted, the approximate location of the display defect of recoverability can be determined, and display defect is marked; 3rd step, directly over regulate the adjustable platform of display defect testing fixture 3 that microscope 32 is moved to display defect that previous step marks, regulates microscope accurately to locate display defect, and obtains the image information of display defect by display device 31; 4th step, opens laser generator, in the real-time monitoring of display device 31 with under instructing, utilizes the laser beam of launching precisely to repair display defect.
For the ease of operation, the lighting system 2 in the present embodiment is designed to portable.
Visible, the oled panel display defect restorative procedure in the present embodiment avoids the resetting of display defect, effectively can improve remediation efficiency and the accuracy rate of display defect.
Although with reference to best interpretations embodiment of the present invention, invention has been described here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the building block of subject combination layout and/or layout.Except the modification of carrying out building block and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
