It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

For convenience of understanding and explanation, the display module and the electronic device provided in the embodiments of the present application are described in detail below with reference to fig. 1 to 7.

Please refer to fig. 1, which is a schematic diagram of a basic structure of a display module according to an embodiment of the present disclosure. The display module 100 includes a liquid crystal panel 101 and a backlight 102 disposed below the liquid crystal panel 101. The backlight source 102 is provided with an opening 103, and a shading tape 104 is folded around the edge of the opening 103. Because the upper folding surface of the light-shielding tape 104 is attached to the backlight source 102, and the lower folding surface of the light-shielding tape 104 is attached to the inner wall of the hole 103, the light of the backlight source 102 cannot reach the hole 103, and the sealing is tight, so that the light-shielding tape 104 cannot shield the glue of the packaging screen, and the light leakage phenomenon is avoided. Preferably, the upper folded surface of the light-shielding tape 104 is attached to the upper surface of the edge of the hole 103 of the backlight 102.

In the embodiment of the present application, the liquid crystal panel 101 is not provided with an opening, and the backlight source 102 is provided with an opening 103. The advantage of this arrangement is that the opening diameter is small and the yield is high during actual manufacturing, while the production cost can be better controlled.

Optionally, the liquid crystal panel 101 and the hole 103 are packaged by a dispensing process. For example, the upper folded surface of the light shielding tape 104 is pasted with a first glue 105, and the lower folded surface of the light shielding tape 104 is pasted with a second glue 106, so that the condition that the light shielding tape 104 shields the glue of the packaging screen is avoided, the sealing is tight, the light leakage is further prevented, meanwhile, the glue width of the packaging screen can be reduced, and the diameter of the hole 103 is reduced.

Optionally, the downward folded surface of the light shielding tape 104 is in any one of a trapezoid shape and a triangle shape. Exemplarily, as shown in fig. 2, it is a schematic view of a light-shielding tape provided in an embodiment of the present application. Because the holes 103 are circular, when the shading tape 104 is turned over downwards, the edge position thereof needs to be cut off, and the pressing action is generated in the actual process, so that the turning surface is trapezoidal or triangular, the cutting and the attaching are convenient, and the production efficiency is improved.

Alternatively, as shown in fig. 3, the backlight 102 includes a bezel 1021, and a light source (not shown in the figure) disposed in the bezel 1021, a reflection sheet 1022, a light guide plate 1023, and an optical film 1024. For example, the optical film 1024 may include, but is not limited to, at least one of a diffusion sheet or a prism sheet. Since only a small amount of light is emitted in the front direction of the light guide plate 1023, and most of the light is emitted at an angle with respect to the normal direction, the diffusion sheet and the prism sheet function to convert the light in the normal direction from the refraction direction to the front direction to improve the front luminance and to uniformize the light diffused by the light guide plate 1023.

Optionally, the iron frame 1021 surrounds the inner wall of the wrapping hole 103, and the lower folded surface of the light-shielding tape 104 is adhered to the surface of the iron frame 1021. This chase 1021 is used for providing the position of pasting for turning over the face down, has avoided shading sticky tape 104 to shelter from the gluey of encapsulation screen from this, and is sealed tight, prevents the light leak phenomenon.

Alternatively, as shown in fig. 4, the liquid crystal panel 101 includes a liquid crystal body 1011, an upper polarizer 1012 disposed above the liquid crystal body 1011, and a lower polarizer 1013 disposed below the liquid crystal body 1011. The lower polarizer 1013 is configured to convert the light beam generated by the backlight 102 into polarized light, and the upper polarizer 1012 is configured to analyze the polarized light after being electrically modulated by the liquid crystal body 1011 to generate light-dark contrast, thereby generating a display image.

Optionally, as shown in fig. 5, the display module 100 further includes a glass cover plate 107 disposed above the liquid crystal panel 101, where the glass cover plate 107 is used to protect the liquid crystal panel 101, and can prevent the external environment from directly damaging the liquid crystal panel 101.

Alternatively, as shown in fig. 6, the hole 103 is opened at any position around the surface of the backlight 102. For example, the holes 103 are disposed at the upper left, upper right, or both sides of the surface of the backlight source 102, so that the display effect of the display module 100 is not affected, and the display module is beautiful and natural.

The embodiment of the application provides a display module, and this display module includes the LCD screen and sets up the backlight in the LCD screen below, wherein the backlight trompil. Because the edge around the hole is turned over and is rolled over and set up the shading sticky tape, the last face of turning over of this shading sticky tape is attached in the backlight, and the lower face of turning over of shading sticky tape is attached in the inner wall in hole for the light of backlight can't reach this hole, and is sealed tight, thereby the shading sticky tape can not shelter from the gluey of encapsulation screen, has avoided appearing the light leak phenomenon, has also reduced the gluey width of encapsulation screen simultaneously, has reduced the hole diameter.
