Description
Technical field
The present invention relates to a kind of fixed frame, particularly relate to a kind of fixed frame of liquid crystal panel.
Background technology
Along with the significantly progressive and the Internet of computing power, the high development of multimedia technology, the transmission of image information at present transfers digital transmission to by simulation mostly.In order to cooperate modern life pattern, it is frivolous that the volume of video signal or device for image day by day is tending towards.Traditional cathode-ray tube (CRT) though still have its advantage, because the structure in internal electron chamber, makes that display is bulky and takes up space, and still has radiant rays to hinder problems such as eye when showing.Therefore, the plane formula display (Flat Panel Display) that cooperates photoelectric technology and semiconductor fabrication to be developed, for example LCD (LCD), organic light emitting display (OLED) or plasma display (Plasma Display Panel, PDP), become the main flow of display product gradually.
With regard to liquid crystal indicator, be broadly divided into direct viewing type displays such as LCD screen, mobile computer, digital lcd TV according to its video picture mode, and non-direct viewing type displays such as liquid crystal projector, back projection TV.In recent years, liquid crystal indicator is gradually towards full-colorization, large scale, high resolving power and trend development cheaply, wherein, because the direct viewing type display still has many restrictions on large scale demonstration and cost, therefore, by having high-resolution non-direct viewing type display panel, silicon wafer panel (LiquidCrystal On Silicon for example, LCOS) or high temperature polysilicon liquid crystal panel (HTPS-LCD) etc., the collocation light engine comes into one's own gradually with liquid crystal projector and the back projection TV that reaches large scale and show.
Yet, because non-direct viewing type display utilizes high-resolution liquid crystal panel in small size, and in conjunction with accurate light engine image amplified and to cast out, therefore the location between liquid crystal panel and the light engine more need be emphasized precisely, and prior art utilizes a fixed frame that liquid crystal panel is fixed on position in the display usually.
Please refer to Figure 1A and 1B, it is respectively the combination and the decomposing schematic representation of existing a kind of panel fixed frame.Panel fixed frame 100 comprises a carrier 110 and two stators 120, carrier 110 is suitable for bearing liquid crystal display panel (not indicating), and stator 120 is disposed at the both sides of carrier 110 respectively, so that liquid crystal panel (not indicating) is clamped on the carrier 110.In addition, carrier 110 has in order to a panel of bearing liquid crystal display panel puts zone 112 and a plurality of pilot hole 114, and pilot hole 114 be disposed at panel put zone 112 around.In addition, dispose a plurality of register pins 124 on the surface of stator 120 corresponding to pilot hole 114, when stator 120 combines with carrier 110, in the pilot hole 114 of register pin 124 corresponding insertion carriers 110, and by a fixing glue (not indicating) set mutually, and liquid crystal panel is fixed in the panel fixed frame 110.
It should be noted that because existing pilot hole is the perforate with smooth internal walls shown in the figure, and the surface of register pin also is a smooth surface that therefore the fixing glue between pilot hole and register pin often can't provide enough adhesion.Thus, though when liquid crystal panel is installed, all pass through accurate calibration actions, but still may in follow-up handling process, cause the relevant position between liquid crystal panel and the light engine to be offset, make display frame the phenomenon of burnt (Defocus or Miss Convergence) occur losing, and then influence the quality of image output.
Summary of the invention
In view of this, purpose of the present invention just provides a kind of panel fixed frame, in order to the relevant position of effective immobile liquid crystal panel in display, and then guarantees the quality of image output.
Based on above-mentioned purpose, the present invention proposes a kind of panel fixed frame, and it is suitable for by a fixing glue fixing the position of a liquid crystal panel, and this panel fixed frame for example comprises a carrier and a plurality of stator.Wherein, carrier for example has a panel and puts zone and a plurality of pilot holes, and carrier is suitable for putting the regions carry liquid crystal panel by panel, and pilot hole is put area configurations around panel.In addition, each stator for example comprises a main body and is disposed at a plurality of register pins on the main body, wherein each register pin by fixing glue and with one of them corresponding connection of pilot hole, and the surface of each register pin has one first limiting section (position limit portion), in order to increase the adhesion between register pin and the fixing glue.
In a preferred embodiment of the invention, the first above-mentioned limiting section for example can have a plurality of first projectioies or a plurality of first depression.Wherein, the kenel of first projection for example comprises particle, zigzag block and schistose texture etc., and the kenel of first depression for example comprises shrinkage pool, helical groove and annular recess etc.In addition, the kenel of register pin of the present invention for example comprises right cylinder and polygon cylinder etc., and the main body of spacer then for example can be tabular, to fit tightly with liquid crystal panel.
In addition, design based on first limiting section on the above-mentioned register pin, panel fixed frame of the present invention also can be formed with second limiting section in pilot hole, second limiting section then equally for example can be the kenel of projectioies such as particle, zigzag block and schistose texture, or is the kenel of depressions such as shrinkage pool, helical groove and annular recess.
Therefore, in not breaking away from spiritual scope of the present invention, panel fixed frame of the present invention except that optionally form on register pin or in the pilot hole separately the first above-mentioned limiting section and second limiting section, also can on register pin with in the pilot hole, form first limiting section and second limiting section respectively simultaneously, and then better bond strength is provided.
Based on above-mentioned, the present invention forms the limiting section of particular design on the surface of the inwall of pilot hole and register pin, in order to increase the adhesion of fixing glue between pilot hole and register pin, with the position of immobile liquid crystal panel in display.Thus, can effectively avoid liquid crystal panel in the process of carrying, to produce skew, and then guarantee the quality of image output.
For above and other objects of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and cooperate appended graphicly, be described in detail below.
