Problems solved by technology

But adhesive tape 96 in the prior art is in application, because frame 91 and glue frame 92 narrow, and adhesive tape 96 is also narrowed thereupon and finally causes adhesive tape 96 to be difficult for cutting
Narrow adhesive tape 96 is prone to problems such as warping even after cutting and adhering

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] figure 2 An adhesive tape 10 according to the invention is shown. Such as figure 2 As shown, the adhesive tape 10 has a narrow side 12 . The narrow side 12 of the adhesive tape 10 may also include a wide side 11 to form a frame structure for matching the backlight module together with the narrow side 12 . The narrow frame 12 has a first portion 13 and a second portion 14 . Wherein, the first part 13 can shield light, and the second part 14 can transmit light. Moreover, the second portion 14 can extend laterally beyond the first portion 13 to increase the width of the narrow side 12 of the adhesive tape 10 .

[0030] It should be noted that the wide side 11 and the narrow side 12 described in this embodiment are obtained by relative comparison, that is, the wide side 11 is the side with the largest width among all the sides, and the narrow side 12 is A side wh...

Abstract

An adhesive tape (10), a backlight module (100), and a liquid crystal display device (200). The adhesive tape (10) comprises narrow sides (12). Each narrow side (12) is provided with a lightproof first part (13) and a light-pervious second part (14). The second part (14) can laterally extend from the first part (13). The width of the adhesive tape (10) is not limited to a narrow frame of the backlight module (100), an attachment area can be increased, and the problems of difficulty in cutting, warping and the like are avoided. In addition, the adhesive tape (10) facilitates the narrow bezel implementation of the liquid crystal display device (200).

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an adhesive tape, a backlight module and a liquid crystal display device. Background technique [0002] The backlight module is a light source located behind the liquid crystal display device, and its luminous effect will directly affect the visual effect of the liquid crystal display module. The LCD panel is a passive light-emitting element. The display panel itself does not emit light, but is illuminated by the backlight module below it. As one of the key components of the liquid crystal display device, the backlight module mainly functions to provide sufficient light for the liquid crystal display. Brightness and evenly distributed light sources enable the liquid crystal display device to display images normally. With the continuous development and innovation of liquid crystal display technology, the liquid crystal display is developing towards the direction of...
