Abstract

The present disclosure provides a display module having: a supporting intermediate frame and a transparent cover plate, wherein the supporting intermediate frame comprises a main plate portion extending in a direction the same as the transparent cover plate and a supporting lateral edge disposed to surround the main plate portion, and the supporting intermediate frame and the transparent cover plate form a first accommodation space; a display unit disposed in the first accommodation space; and a control board disposed at a side of the main plate portion away from the display unit, wherein the control board is electrically connected to the display unit to transmit a display signal to the display unit; wherein the supporting intermediate frame further has at least one fixing portion disposed at a side of the main plate portion away from the display unit for fixing the control board. The present disclosure also provides a method for manufacturing the display module and an electric device comprising the display module.

First claim

What is claimed is:

1 . A display module comprising: a supporting intermediate frame and a transparent cover plate, wherein the supporting intermediate frame comprises a main plate portion extending in a direction the same as the transparent cover plate and a supporting lateral edge disposed to surround the main plate portion, and the supporting intermediate frame and the transparent cover plate form a first accommodation space; a display unit disposed in the first accommodation space; and a control board disposed at a side of the main plate portion away from the display unit, wherein the control board is electrically connected to the display unit to transmit a display signal to the display unit; wherein the supporting intermediate frame further comprises at least one fixing portion disposed at a side of the main plate portion away from the display unit for fixing the control board; wherein the supporting lateral edge and the main plate portion form a second accommodation space, and at least a part of the control board is disposed in the second accommodation space; and wherein the supporting lateral edge comprises a first sub-supporting lateral edge, which is disposed to surround the control board and forms a lateral barrier for the second accommodation space.

2 . The display module according to claim 1 , wherein the fixing portion is a supporting fixing pillar comprising a supporting portion at a side close to the main plate portion and a connecting portion at a side away from the main plate portion; wherein the connecting portion comprises a position-limiting portion and a fixing head, and one end of the position-limiting portion is connected to the supporting portion, and the other end of the position-limiting portion is connected to the fixing head; and wherein the control board comprises a position-limiting hole penetrating the control board, the position-limiting portion passes through the position-limiting hole, and the supporting portion and the fixing head are disposed at both sides of the control board respectively and cooperate with the position-limiting portion to fix the control board.

3 . The display module according to claim 2 , wherein a material for the fixing portion comprises a hot melt material.

4 . The display module according to claim 1 , wherein the display unit is electrically connected to the control board via a flexible circuit board; and the main plate portion comprises a first through hole, and the flexible circuit board passes through the first through hole; the control board comprises a second through hole, and the flexible circuit board passes through the second through hole and is connected to a side of the control board away from the main plate portion; and the display module further comprises a sealing tape, whose orthographic projection on an extending plane of the control board covers the second through hole.

5 . The display module according to claim 4 , wherein the control board comprises a second through hole, and the flexible circuit board passes through the second through hole and is connected to a side of the control board away from the main plate portion; the control board comprises a control board body and a flexible circuit board connector disposed at a side of the control board body away from the main plate portion, the flexible circuit board connector is disposed adjacent to the second through hole, and the flexible circuit board connector comprises a flexible circuit board connecting terminal; the second through hole is a strip-shaped through hole, and the flexible circuit board connecting terminal extends in a direction the same as an extending direction of the second through hole; and the second through hole is disposed at an edge of the control board, and the flexible circuit board connector is closer to a center of the control board than the second through hole.

6 . The display module according to claim 5 , wherein the control board body comprises a first position-limiting hole disposed between the second through hole and a first edge of the control board body; and an orthographic projection of a center of the first position-limiting hole on a hole edge of the second through hole close to the first position-limiting hole is located within a middle ⅓ section of an entire length of the hole edge; and the fixing portion comprises a first sub-fixing portion cooperating with the first position-limiting hole for fixing.

7 . The display module according to claim 6 , wherein the control board comprises a touch unit connector disposed at a side of the control board body away from the main plate portion; and when a circle is drawn with a center of the control board body as an origin on a plane in which the touch unit connector is located, and the circle has an area covering 1/9 of an area of the control board, an orthographic projection of the touch unit connector on the control board body has a center inside the circle.

8 . The display module according to claim 7 , wherein the touch unit connector comprises a touch unit connecting terminal which is configured to allow a touch unit connecting cable to extend in a direction away from the flexible circuit board connector.

9 . The display module according to claim 8 , wherein the display module comprises a touch unit connected to the touch unit connecting terminal via the touch unit connecting cable;
the control board body comprises a second position-limiting hole which is disposed adjacent to a second edge of the control board, wherein the second edge is located opposite to the first edge; the second position-limiting hole is disposed adjacent to the touch unit connecting cable; an orthographic projection of the touch unit connecting cable on the control board does not overlap with the second position-limiting hole; and the fixing portion comprises a second sub-fixing portion cooperating with the second position-limiting hole for fixing.

10 . The display module according to claim 9 , wherein the control board comprises a power input connector disposed at a side of the control board body away from the main plate portion; the power input connector is located at one side of a surface of the control board body divided by an orthographic projection of an axis of the touch unit connecting cable on the surface of the control board body; and the power input connector comprises a power input connecting terminal which is configured such that a power connecting cable extends towards an edge of the control board body in a direction at an angle other than 0° and 180° with respect to an extending direction of the touch unit connecting cable.

11 . The display module according to claim 10 , wherein the control board comprises a speaker connector disposed at a side of the control board body away from the main plate portion; wherein the speaker connector is located at the other side of the surface of the control board body divided by the orthographic projection of the axis of the touch unit connecting cable on the surface of the control board body, other than the side at which the power input connector is located; and the speaker connector comprises a speaker connecting terminal which is configured such that the speaker connecting cable extends towards the edge of the control board body in a direction at an angle other than 0° and 180° with respect to the extending direction of the touch unit connecting cable.
