Description
Technical field
The present invention relates to a kind of LCD, particularly relate to LCD with the framework that can adjust the bearing area size.
Background technology
In every image display technique, LCD since have in light weight, volume is little, power consumption is low, advantage such as radiationless, be used in widely in the various devices.
See also Fig. 1, it is the synoptic diagram of a LCD primary clustering.As shown in the figure, a LCD mainly comprises a liquid crystal panel 10, a backlight module 11 and a framework 12.
Framework (Frame) 12, be cover cap on backlight module 11, can make liquid crystal panel 10 be positioned at backlight module 11 light ejaculations place in order to bearing liquid crystal display panel 10, and the light show image that can be provided by backlight module 11.
And, more can be provided with four rectangular projections 121 (or location structure) on framework 12 surfaces in order stably liquid crystal panel 10 to be positioned at position suitable on the framework 12, be separately positioned on four corners of framework 12.In when assembling, liquid crystal panel 10 is embedded on the framework 12, that is is closely against the inner edge of four projections 121 respectively, and liquid crystal panel 10 is fixed on the rectangular area that four projections 121 are surrounded (below be referred to as supporting region) with 10 4 corners of liquid crystal panel.
Yet on practice, liquid crystal panel 10 but often has size difference to cause the bad situation of collocation to take place with framework 12, causes the difficulty in the assembling.
For instance, liquid crystal panel 10 is just cut apart by the sliver cutter pouring into after the liquid crystal material involution finishes, and large-sized liquid crystal panel is cut into less required size.And when cutting, inevasible, the size of each liquid crystal panel all has difference slightly.
And it is similar, generally speaking framework 12 is to be plastic products, utilize the mould injection molding, and after manufacturing was finished, the interference owing to the shrinkage factor of material, the size difference of mould structure or the like every factor also can make the size of framework 12 error occur, in other words, in each framework 12, the size and the shape of the supporting region that four projections 121 are crossed, difference all to some extent.
See also Fig. 2, synoptic diagram when it is placed in framework 12 for liquid crystal panel 10, as shown in the figure, when the supporting region size on liquid crystal panel 10 and the framework 12 to some extent during difference, if liquid crystal panel 10 is the benchmark anchor point with one of them projection 121 on the framework, then its edge and other projection are 121, promptly can produce space S, make liquid crystal panel 10 may produce displacement on framework 12.。
Even screening by product control work, liquid crystal panel 10 and framework 12 both sizes are separately dropped in the permissible separately margin tolerance, the situation that still can't avoid the supporting region size of liquid crystal panel 10 and framework 12 not to be inconsistent takes place, (for example one limit on the upper side when particularly both sizes are offset to the tolerance tolerable limit separately, one limit on the lower side), the influence that space S is brought will be more obvious.
And in order to reduce the influence that aforementioned interspace S is brought, mostly existing settling mode is to solve this problem by the mode of pasting blob of viscose (Rubber).That is be, when liquid crystal panel 10 during,, insert space between the two and be pasted on surface both promptly to have viscosity and flexible blob of viscose less than the supporting region on the framework 12, liquid crystal panel 10 is held out against in the corner as the projection 121 of benchmark, with immobile liquid crystal panel 10 on framework 12.
See also Fig. 3, as shown in the figure, be a liquid crystal panel 10 and be pasted on synoptic diagram on the framework 12 by blob of viscose 13.
Yet this kind mode still has many shortcomings.For example, in manufacture craft, in order to paste blob of viscose 13 in the appropriate location, need labor intensive attach one by one, except stickup speed is slow, outside efficient is not good, easier because of human factor cause attach bad (such as be pasted not strongly by, subsides malposition or the like), and must spend the material cost of blob of viscose 13, and high manpower expense.
In addition, after the LCD assembling is finished, how to watch for the user, make that liquid crystal panel 10 wherein also is in upright mode, be embedded in the framework 12 in upright mode.Wherein, at the blob of viscose 13 of LCD lower position, under the compressing that is subjected to liquid crystal panel 10 weight for a long time, be easy to generate distortion and sink; And blob of viscose 13 is also aging or the influence of LCD internal high temperature causes it rotten because of blob of viscose material or gum easily, and changes viscosity and elasticity originally, is difficult to liquid crystal panel 10 is fixed in initial position.It is crooked that above-mentioned shortcoming all can make the position of liquid crystal panel 10 produce, and has a strong impact on picture quality.
So, how can effectively improve the problems of bringing because of the difference of liquid crystal panel and framework size, and to promote efficient and the cost of producing simultaneously, be the direction of endeavouring to solve for those skilled in the art.
