Embodiment Construction

[0024] In order to make those skilled in the art better understand the technical solutions of the present application, the aging treatment equipment and the aging treatment method of the display panel provided by the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The display panel is provided with a plurality of light-emitting elements. During the working process of the light-emitting elements, the aging speed in the early stage is too fast, and the aging speed in the later stage is relatively stable. In order to improve the display performance of the display panel, the display panel needs to undergo an aging treatment during the manufacturing process, so that the material properties of the light-emitting elements in the display panel reach a stable state in the later stage before being put into use. The display panel can be subjected to burn-in treatment by burn-in treatment equipment.

Abstract

The present application provides an aging treatment device and an aging treatment method for a display panel, wherein the aging treatment device includes a pulse generator and at least one switching device connected to the pulse generator; The panel provides driving signals; the pulse generator includes a first output pin group and a second output pin group, and the voltage timings of the first output pin group and the second output pin group are the same; the switching device includes at least a first connector and the second connector, the first output pin group is correspondingly connected to the first connector, and the second output pin group is correspondingly connected to the second connector. The aging treatment device of the present application improves the driving capability, thereby reducing the aging current and eliminating the phenomenon that the aging current is too large to cause damage to the device.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an aging treatment device and an aging treatment method for a display panel. Background technique [0002] The display panel needs to be subjected to aging treatment (Aging) during the manufacturing process, so that the brightness attenuation of the material is low in the use stage. The equipment used for aging treatment is called aging treatment equipment. The aging treatment apparatus causes each pixel unit on the display panel to be aged by applying periodic pulses to the display panel. [0003] However, in the prior art, when the display panel is subjected to burn-in treatment, a high current may be generated that is greater than the working current of the burn-in treatment equipment. General equipment is not suitable for long-term operation under high power, and there is a risk of hardware circuit damage. If the hardware circuit is burned out, it will affe...
