Description

A kind of display module of light leakage
Technical field
The utility model is related to display technology field more particularly to a kind of display modules of light leakage.
Background technology
Existing display module generally comprises display panel i.e. glass and the backlight of light source is provided for glass, is showing During module produces and processes, in order to avoid backlight is scratched, generally layer protecting film can be attached in the bottom of backlight, The area of the protective film is identical with the bottom area size of backlight, is needed during subsequent processing procedure to the side wall of backlight Upper shading adhesive tape avoids display module from light leakage phenomena occur, but since the width of shading adhesive tape is equal to during attaching The width of backlight side wall, when attaching it is easy to appear displacement, when shading adhesive tape occurs to bottom offset, it is easy to just attach To the edge of protective film, and during subsequently protective film is removed, protective film can take up shading adhesive tape again, and need to comfort again The edge of flat shading glue, process increase;When shading adhesive tape shifts up, just without screening at the lower end position of backlight side wall The covering of optical cement item simultaneously because LED light is located at the side wall lower ends of backlight, therefore can cause display module apparent leakage occur Light, in conclusion the attached process of existing shading adhesive tape is more, attaching difficulty is big, by the light leak wind of the display module of its assembling Danger is also higher.
Utility model content
The utility model provides a kind of display module of light leakage, the shading adhesive tape attached process in the display module Few, attaching difficulty is small, good shading effect, can effectively reduce the light leak risk of display module.
The utility model is the technical scheme adopted is that a kind of display module of light leakage, which is characterized in that including under Protective film, backlight, glass cover-plate are set gradually upwards, the protective film is attached on the bottom wall of backlight and its area is small In the bottom wall area of backlight;Shading glue is respectively equipped on left side wall and bottom wall, right side wall and bottom wall in the backlight Item, the shading adhesive tape include the first occlusion part on the bottom wall of backlight and the left side wall positioned at backlight or right side The second light shielding part on wall, first occlusion part is between the edge of the edge of protective film one side and the protective film Leave the width of the backlight described in gap, the width of the second light shielding part etc..
After the above technical solution is adopted, the utility model has the following advantages compared with prior art:
In the utility model, shading adhesive tape is blocked simultaneously on the bottom wall and side wall of backlight, can effectively avoid because Shading adhesive tape leakage problem caused when shifting up, while the edge of the edge of protective film and the first occlusion part is that there are one Fixed gap, therefore it, convenient for being not easy to adhere to protective film, is subsequently removing protective film when the downward displacement of shading adhesive tape In the process without carrying out secondary attaching again, attached process is reduced, while the first occlusion part can be also used for protection backlight, avoid Its bottom is scratched.
As an improvement, first occlusion part is mutually perpendicular to second light shielding part, convenient for attaching.
As an improvement, the scope in the gap is 2mm~5mm, gap is too small easily to stick protective film, the too big back of the body in gap The risk that light source is scraped off is larger, and by verifying that above-mentioned distance range is most suitable, when subsequently removing protective film, protective film will not The first occlusion part is taken up, so without secondary attaching, process is reduced.
As an improvement, one end of second light shielding part is extended on the front side wall of the backlight described Front side wall end, prevent the corner that the front side wall of backlight and left side wall or right side wall are formed from light leak occur, simultaneously It can prevent the shading adhesive tape being located on left side wall or right side wall from coming off.
As an improvement, first occlusion part and the second light shielding part is integrally formed, easy to process and attaching shading glue Item.

Specific embodiment
As depicted in figs. 1 and 2, a kind of display module of light leakage, including setting gradually protective film 1, backlight from bottom to top Source 2, glass cover-plate 3, protective film 1 is attached on the bottom wall 21 of backlight and its area is less than the bottom wall area of backlight;It is carrying on the back Shading adhesive tape 4 is respectively equipped on the left side wall 22 and bottom wall 21 of light source 2, right side wall 23 and bottom wall 21, shading adhesive tape 4 includes being located at The first occlusion part 41 on the bottom wall 21 of backlight and the second light shielding part on the left side wall 22 of backlight or right side wall 23 42, the first occlusion part 41 leaves gap 5, the scope in gap 5 between the edge of 1 one side of protective film and the edge of protective film 1 For 2mm~5mm, the width of the backlights such as the width of the second light shielding part.Knob is additionally provided on protective film, convenient in subsequent work Protective film is removed in sequence.One end of second light shielding part 42 is extended on the front side wall 24 of backlight at the end of front side wall 24 Portion.First occlusion part 41 and the second light shielding part 42 are integrally formed, and the first occlusion part 41 and the second light shielding part 42 are orthogonal It is arranged on backlight 2, flexible PCB i.e. FPCA plates 6 is additionally provided on backlight.
As shown in Fig. 2, when the bottom wall of backlight places display module upwards, FPCA plates are folded on the downside of backlight, this When shading adhesive tape 4 top view be inverted " L " type.The utility model is simple in structure, and shading adhesive tape can not only block backlight The light of source left side wall, right side wall, left side wall and front side wall, right side wall and front side wall junction, moreover it is possible to ensure protective film side Just on the premise of removing backlight is protected to avoid being scraped off, therefore the attached process of the shading adhesive tape of the utility model is few, attaches Difficulty is low, and leakproof light effect is good, and display module production efficiency is high, good quality.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations.Although with reference to foregoing reality Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that, it still can be to preceding The technical solution recorded in embodiment stated modifies or carries out equivalent substitution to wherein each several part technical characteristic, such as First occlusion part and the second light shielding part are independent from each other part, can individually attach, and these modifications or replacement, do not make The essence of appropriate technical solution departs from the scope of the utility model embodiment technical solution.
