preparation example Construction

[0078] The method for manufacturing a display panel according to the first embodiment of the present application includes the following steps:

[0079] Step S1: providing an array substrate 11;

[0080] Step S2: sequentially transferring multiple first chips 12 and multiple second chips 13 onto the array substrate 11, the multiple first chips 12 emit blue light, and some of the first chips 12 are excitation chips 12a;

[0081] Step S3: forming a color conversion layer 14 on the excitation chip 12a, the color light excited by the color conversion layer 14, the color light emitted by the plurality of first chips 12 and the color light emitted by the plurality of second chips 13 The color light varies.

[0082] The manufacturing method of the display panel in the first embodiment only needs to transfer the first chip 12 and the second chip 13 twice, and then form the color conversion layer 14 on the excitation chip 12a, so that the excitation chip 12a emits light and excites the...

Abstract

The invention provides a display panel and a preparation method thereof, the display panel comprises an array substrate, a first chip, a second chip and a color conversion layer, the first chip is arranged on the array substrate, the first chip emits blue light, and part of the first chip is an excitation chip; the second chip is arranged on the array substrate; the color conversion layers are arranged on the excitation chips in a one-to-one correspondence manner; and the excited color light of the color conversion layer, the color light emitted by the first chip and the color light emitted bythe second chip are different. According to the method, only the first chip and the second chip need to be transferred twice, and then the color conversion layer is formed on the excitation chip, sothat the excitation chip emits light to excite the color conversion layer to emit light of another color; and, according to the method, the chip does not need to be transferred for three times, and the preparation effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Micro light-emitting diodes, a new technology regarded by many manufacturers as the next-generation display, have the advantages of much less power consumption than liquid crystal displays, better brightness than organic light-emitting displays, and self-illumination. Its main feature is the new technology of shrinking the existing LED (Light Emitting Diode, light-emitting diode) from millimeters to microns (generally less than 50 microns in size) and then arraying them. [0003] Because it is a self-luminous technology, it is necessary to transfer chips of different colors to the backplane according to the design of the pixels when it is used as a full-color display. However, it is time-consuming to transfer the three chips continuously, and it is easy to be affected by the transfer. bi...
