Abstract

The invention provides a display panel preparation method and a display panel. The preparation method of the display panel comprises the steps of forming a substrate; forming a bearing layer on one side of the substrate and a reflecting layer borne on the bearing layer; a thin film transistor array layer and a light-emitting layer are stacked on the side, away from the substrate, of the bearing layer, the thin film transistor array layer comprises a plurality of thin film transistors, and semiconductor layers of the thin film transistors correspond to the reflecting layers; and irradiating one side, deviating from the reflecting layer, of the substrate by using preset light so as to strip the bearing layer from the substrate. According to the preparation method of the display panel, the preset light does not irradiate the semiconductor layer, the grain size and the lattice structure of the semiconductor layer can be kept unchanged, then it is guaranteed that currents are kept consistent when the thin film transistors at different positions are started, the brightness uniformity of the display panel is improved, and the display frame of the display panel is more uniform.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a method for manufacturing a display panel and a display panel. Background technique [0002] With the development of optoelectronic display technology and semiconductor manufacturing technology, displays with thin film transistors (ThinFilm Transistor, TFT) have become more and more mature, such as Thin Film Transistor Liquid Crystal Display (TFT-LCD) or organic light emitting diodes Displays (Thin FilmTransistor Organic Light-Emitting Diode, TFT-OLED) have been successfully mass-produced. In terms of thickness, color saturation, contrast, flexible display, etc., OLED displays have obvious advantages, and the development of OLED displays has broad prospects. [0003] However, the OLED display panel in the related art has problems such as different brightness and uneven display in each area. SUMMARY OF THE INVENTION [0004] The purpose of the present applicat...
