Abstract
The invention provides a liquid crystal display device, which comprises a panel, a light guide plate, an optical diaphragm, a rubber frame and an outer frame, wherein the light guide plate is positioned below the panel; the optical diaphragm is positioned between the panel and the light guide plate, and a lug is arranged on a side edge of the optical diaphragm; the rubber frame is provided with a first retaining wall and a second retaining wall which are vertical to each other; the panel is arranged on the second retaining wall, and the second retaining wall is provided with an opening corresponding to the lug; the opening divides the second retaining wall into a third retaining wall and a fourth retaining wall; a light absorbing structure attaches to the third retaining wall, is vertical to the side all of the optical diaphragm, and covers a gap which is formed when the lug is inserted into the opening; and the outer frame is provided with an accommodation space. By adopting the liquid crystal display device, the problem of light leakage can be solved without enlarging the outer frame.
Description
Technical field
The present invention relates to a kind of liquid crystal indicator, relate in particular to a kind of liquid crystal indicator of avoiding light leak.
Background technology
Existing notebook computer (Note Book is abbreviated as NB) mostly with 20 ° up and down at visual angle, about 40 ° design.But the information products that have light, thin, short, little portability in recent years are considerably noticeable, and flat computer is a kind of new trend.Because flat computer is full visual angle; Be all 85 ° application up and down, no matter any visual angle all requires not have the perfect quality of light leak, complete all do not have the requirement of outer light leak in order to reach the visual angle; The method that solves has the housing of increasing, increases glass now, makes visible area good more far more apart from glass edge.Analyze with light path, become the visual angles of 85 degree by the visual angle of 20-40 degree, with 10.1 cun be example, housing need respectively increase 6-7mm at least up and down, such solution can be gained in weight, area, can't accomplish compact design.When not increasing housing if only strengthen light guide plate and blooming piece, the glue frame just dwindles such as meeting, and its constant intensity can reduce.
In view of this, how to design a kind of novel liquid crystal indicator, under the prerequisite that does not increase housing, the glue frame also has stronger bed knife, and can to avoid light leak be the problem that those skilled in the art need solution badly.
Summary of the invention
To all not having light leak for reaching full visual angle in the prior art, do not increase again the glue frame attenuation that exists under the situation of housing, the defective that intensity weakens the invention provides a kind of liquid crystal indicator.
According to the invention provides the present invention a kind of liquid crystal indicator is provided, comprises: panel, light guide plate, blooming piece, glue frame and housing.Wherein, light guide plate is positioned at the below of panel; Blooming piece is between panel and light guide plate, and a side of blooming piece is provided with a lug; The glue frame has orthogonal first barricade and second barricade, and panel rack is located on second barricade, and second barricade is provided with an opening corresponding to lug, and opening is divided into the 3rd barricade and the 4th barricade with second barricade; The extinction structure is attached on the sidewall of the 3rd barricade perpendicular to blooming piece, and covers in the gap that when lug inserts opening, stays; And housing has a spatial accommodation.
Preferably, panel is a liquid crystal panel.
Preferably, more comprise polaroid and following polaroid, panel is located between the upper and lower polaroid.
Preferably, extinction material can be processed by adhesive tape, rubber or printing ink.
Preferably, housing can be chase or plastic cement frame.
Preferably, more comprise a light source.
Preferably, light source can be light emitting diode.
Preferably, housing more comprises first housing and second housing, and first housing and second housing form an accommodation space, and first housing and second outer frame part are overlapping.
Preferably, flat diffusion sheet, brightness enhancement film or the prismatic lens of comprising of blooming.
Adopt liquid crystal indicator of the present invention, can not increase under the housing situation, strengthen the intensity of glue frame and avoid the light leak problem.
Description of drawings
The reader will become apparent various aspects of the present invention after having read the specific embodiment of the present invention with reference to accompanying drawing.Wherein,
Fig. 1 shows the diagrammatic cross-section according to liquid crystal indicator of the present invention.
Embodiment
With reference to the accompanying drawings, specific embodiments of the invention is described in further detail.
Fig. 1 shows the diagrammatic cross-section according to liquid crystal indicator of the present invention.With reference to Fig. 1, liquid crystal indicator 10 comprises: liquid crystal panel 100, light guide plate 110, blooming piece 120, glue frame 130, extinction structure 140, first housing 150, second housing 160 and light source (not illustrating).Light guide plate 110 is positioned at the below of liquid crystal panel 100.Blooming piece 120 can be diffusion sheet, brightness enhancement film or prismatic lens, and between liquid crystal panel 100 and light guide plate 110, a side of blooming piece 120 is provided with lug 121.Glue frame 130 has first barricade 131 and second barricade, 132, the first barricades 131 perpendicular to second barricade 132, and liquid crystal panel is set up on second barricade 132.Second barricade 132 has the lug 121 corresponding settings on an opening (indicate) and the blooming piece 120, and lug 121 can be sticked in the opening.
Owing to increased blooming, do not increase housing again thereupon, the intensity of glue frame 130 just weakens relatively, therefore, the intensity that can increase glue frame 130 that cooperates of lug 121 and opening, and fixed optics diaphragm 120 better.Opening is separated into the 3rd barricade 133 and the 4th barricade 134 with second barricade 132.
Continuation is with reference to Fig. 1, and extinction structure 140 is attached on the lateral wall (not indicating) of the 3rd barricade 133 perpendicular to blooming piece 120, and extinction structure 140 covers the gap that stays when lug 121 inserts opening.Because the design of glue frame 130 upper sheds, light can expose away from opening part, so extinction structure 140 can absorb these light that expose and prevent light leak.Extinction structure 140 can be a sheet, also can be a sheet rubber, can also be processed by printing ink.First housing 150 and second barricade 132 holding liquid crystal panels, 100, the second housings 160 and second barricade, 132 clamping light guide boards 110, and first housing 150 and second housing 160 are overlapped.In the present embodiment, first housing 150 and second housing 160 are chase, and in a further embodiment, first housing 150 and second housing 160 can also be the plastic cement frame, or one be chase, and another is the plastic cement frame.In a further embodiment, liquid crystal indicator 10 more comprises polaroid and following polaroid, and liquid crystal panel 100 is located between polaroid and the following polaroid.
Adopt the present invention when increasing light guide plate, blooming piece, not increase under the situation of housing, can strengthen the intensity of glue frame, can avoid the problem of light leak again.
Above, describe the specific embodiment of the present invention with reference to the accompanying drawings.But those skilled in the art can understand, and under situation without departing from the spirit and scope of the present invention, can also specific embodiments of the invention do various changes and replacement.These changes and replacement all drop in claims restricted portion of the present invention.
