Problems solved by technology

However, as shown in Figure 2, the side of the liquid crystal display module 10 As shown in angle 16, the backlight module 14 may have a curvature, so after the display panel 12 is arranged on the backlight module 14, the display panel 12 will be deformed.
Such deformation will cause a slight abnormality in the arrangement of liquid crystals inside the display panel 12, resulting in uneven brightness and light leakage when the light from the backlight module 14 passes through the corners 16 of the display panel 12.

Embodiment Construction

[0089] Figure 4 and Figure 5 A first embodiment of the liquid crystal display module of the present invention is shown. refer to Figure 4 and Figure 5 , the liquid crystal display module 20 includes a display panel 22 , a bonding layer 24 and a backlight module 26 . The display panel 22 is disposed on the backlight module 26 , and the adhesive layer 24 is sandwiched between the backlight module 26 and the display panel 22 . The adhesive layer 24 may be a light-shielding tape.

[0090]The backlight module 26 has a curvature so that the middle of the backlight module 26 is higher than the two sides. For easy understanding, the first side 262 of the backlight module 26 is taken as an example for illustration. The first side 262 of the backlight module 26 has the curvature, and the curvature of the curvature increases from the center of the first side 262 to both sides. Corresponding to the position of the first side 262 , the bonding layer 24 has an adjustment surface ...

Abstract

The invention provides a liquid crystal display module. The liquid crystal display module comprises a backlight module having a curvature, a display panel and a bonding layer. The display panel is arranged on the backlight module. The bonding layer is clamped between the backlight module and the display panel and provided with an adjusting surface facing the backlight module, and the adjusting surface is matched with the curvature. The bonding layer can prevent the display panel from deforming due to the curvature and further prevent light leakage.

Description

technical field [0001] The invention relates to a display module, and in particular to a liquid crystal display module with improved light leakage. Background technique [0002] figure 1 It is a perspective view of a conventional liquid crystal display module. Such as figure 1 As shown, the conventional liquid crystal display module 10 includes a display panel 12 for displaying images and a backlight module 14 for providing light to the display panel 12 . Under ideal conditions, the display panel 12 and the back module 14 are completely attached, and the connecting surface of the two is a flat surface, such as figure 1 shown. However, if figure 2 As shown by the corner 16 of the liquid crystal display module 10 in the center, the backlight module 14 may have a degree of curvature, so after the display panel 12 is disposed on the backlight module 14 , the display panel 12 will be deformed. Such deformation will cause a slight abnormality in the liquid crystal arrangeme...
