AI Technical Summary
The bending dimensions of existing LCD display modules are too large, which cannot meet the requirements for narrow bezels.
The inner sealing adhesive is used instead of the first-line adhesive, the solder resist ink layer is used instead of the thermosetting ink layer, and the outer edge of the backlight module is flush with the outer edge of the display glass to reduce the size occupied by the thermosetting ink layer and the impact of the backlight module on the bending area.
It effectively reduces the bending width of the display module to 0.45mm, thereby reducing the bezel width of electronic devices and increasing the screen-to-body ratio.

[0002] In liquid crystal display module, module FPC is bound on liquid crystal display glass, and module FPC is fixed on the back of backlight module after being bent subsequently, in conventional liquid crystal display module, heat -setting green oil and a line glue are arranged on the back of module FPC to play corresponding protection effect, under this structure, the factors that influence the bending size of module FPC are: 1, the distance between the edge of heat -setting green oil on the back of module FPC and the edge of display glass, this size is generally greater than or equal to 0.2mm;2, the distance between the bending single layer area starting bending line on the front of module FPC and the edge of heat -setting green oil on the back, this size is generally greater than or equal to 0.4mm;3, the distance between the edge of heat -setting green oil and the edge of binding PAD of actual glass, this size is generally greater than or equal to 0.3mm;4, the distance between the edge of the appearance of backlight module and the edge of corresponding display glass, this size is generally greater than or equal to 0.5mm;5, the width of a line glue is about 0.6mm, based on the above structure, when module FPC is bent, the bending size of the existing display module is generally greater than or equal to 0.9mm, so in order to ensure smooth assembly, the corresponding position of whole machine also needs to reserve at least 0.9mm position to accommodate module FPC bending. But at present, in order to pursue better narrow frame effect, the display module under the existing bending size still cannot meet the demand.
[0003] Therefore, the prior art has defects and needs to be improved. INVENTION CONTENTS
[0004] The utility model aims at overcoming the insufficient of prior art, provide a kind of display module and electronic equipment that can reduce bending size.
[0005] The technical scheme of the utility model is as follows: the utility model provides a kind of display module that can reduce bending size, comprising: display glass, module FPC and backlight module, the module FPC is bound on the display glass, the back of the module FPC is formed with solder resist layer in bending area, the backlight module is stacked and is set in the lower layer of the display glass, at the bending area one end close to the module FPC, the appearance edge of the backlight module does not exceed the corresponding appearance edge of the display glass, the module FPC is fixed on the back of the backlight module after being bent, and inner sealant is equipped at the bending area of the back of the module FPC, and the inner sealant is pasted on the back of the module FPC, the side of display glass and the side of backlight module.
[0006] Preferably, at one end close to the bending area of the module FPC, the contour edge of the backlight module is flush with the corresponding contour edge of the display glass.
[0007] The utility model discloses still provide a kind of electronic equipment, including the display module of the above-mentioned can reduce bending size, the electronic equipment further includes equipment mainboard, and the module FPC of display module is electrically connected with the equipment mainboard.
[0008] With the above scheme, the utility model has the beneficial effects that by setting inner sealant to replace existing one-line glue, the space occupied by one-line glue in the bending area is avoided, by replacing the heat-set ink layer with the solder resist layer, higher processing precision can be obtained, the occupied size of the heat-set ink layer is reduced, by reducing the edge of the backlight module not exceeding the display glass, the problem of increased width of the bending area caused by the backlight module is avoided, and by the above structure, the bending width size of the display module can be effectively reduced, so that the bending width can be minimized to 0.45mm, and the frame width of the electronic equipment is effectively reduced. BRIEF DESCRIPTION OF DRAWINGS
