[0057] Please refer to Figure 4 , Figure 4 It is a flow chart of the manufacturing method of the display module according to the embodiment of the present application. A method for manufacturing a display module 100 according to an embodiment of the present application includes the following steps:

[0058] Step S1: sequentially forming a first electrode layer and a second electrode layer on the display panel, the potential of the first electrode layer being lower than that of the second electrode layer;

[0059] Step S2: forming a photoresist layer on the second electrode layer, and patterning the photoresist layer to form openings;

[0060] Step S3: Etching the parts of the first electrode layer and the second electrode layer corresponding to the opening, so that the opening penetrates the first electrode layer and the second electrode layer;

[0061] Step S4: using a stripping solution to strip the photoresist layer, the first electrode layer and the second electrode l...

Abstract

The invention provides a display module and a preparation method thereof. In the display module, a first electrode layer is arranged on a display panel; a second electrode layer is arranged on the first electrode layer; an exciter is arranged on the second electrode layer; an opening penetrates through the first electrode layer and the second electrode layer; at the periphery of the opening, the suspended part of the second electrode layer, the side wall of the first electrode layer and the display panel define a sound production cavity; and the sound production cavity is communicated with theopening. According to the invention, the part, which is overlapped on the first electrode layer, of the second electrode layer is suspended, so that the suspended part, the side wall of the first electrode and the display panel define the sound production cavity for sounding, and the effects of saving the cost and maintaining the strength of the display substrate are achieved.

Description

technical field [0001] The present application relates to a display technology, in particular to a display module and a preparation method thereof. Background technique [0002] The existing screen sound generation technology on the market is basically an under-screen sound generation technology. The general solution is to attach a vibrator to the middle frame of the mobile phone, and then drive the mobile phone screen to vibrate to generate sound. The sound effect of this technology is poor, and the waste of energy consumption is obvious. There is also a solution to dig a hole on the screen, and then attach the vibrator above the hole to form a sound-emitting microcavity, but this method is costly, and digging a hole on the screen substrate will weaken the strength of the display substrate, and digging The hole process yield is also difficult to guarantee. Contents of the invention [0003] Embodiments of the present application provide a display module and a manufactur...
