Description

Laser beam inspection device for repairing panel

Technical Field

The utility model relates to the technical field of display device manufacturing equipment, in particular to a laser beam inspection device for panel repair.

Background

Referring to fig. 1, the light emitting panel includes a substrate 2 ', a display area 21 ' and an edge area 22 ' located at the edge of the display area 21 ', a plurality of distributed light emitting components (e.g., LEDs or OLEDs) in a rectangular array are disposed in the display area 21 ', and light emission of each light emitting component is controlled by one control loop.

When the light-emitting panel is manufactured, abnormal light emission occurs in a part of the display area 21 ', for example, the light-emitting part is brighter or darker, so that bright spots or dark spots occur in the display area 21', which affect the quality of the light-emitting panel, and therefore, the light-emitting part with abnormal light emission needs to be repaired. When repairing a light emitting component, a control circuit connected to the light emitting component having abnormal light emission is usually cut off by using the laser emitter 1', and then the light emitting component is connected to a normal control circuit. The laser transmitters 1 'are arranged above the light-emitting panel at intervals, and the laser transmitters 1' can horizontally move to be right above the control loop to be cut. Because the control loop is formed by a thin copper layer with smaller width, and the distance between two adjacent control loops is smaller, the spot size of the laser beam needs to be controlled to be slightly larger than the width of the thin copper layer, so that the control loop which emits light normally due to the overlarge laser beam is prevented from being cut by mistake, and in addition, the energy of the laser beam needs to be controlled within a proper range, so that the laser can be ensured to cut off the control loop completely and damage to the substrate 2 'due to the overlarge laser energy, and therefore, the laser beam needs to be inspected before the laser emitter 1' cuts the control loop.

In the prior art, before the laser emitter 1 'cuts the control loop, a laser beam is irradiated into an edge area 22' of the substrate 2 ', whether the laser beam meets the cutting requirement is judged by observing a cutting trace 23' of the laser beam on the edge area 22 'by a human eye, and when the laser beam meets the cutting requirement, the laser emitter 1' is moved to the position right above the control loop to be cut. However, in this inspection method of the laser beam, whether the laser beam meets the requirements is judged by observing the cutting trace 23 'of the laser beam by naked eyes, the inspection is not accurate enough, and if foreign matters exist on the edge area 22', the inspection result is affected.
