Description

LCD assembly and framework

Technical field

The present invention relates to a kind of LCD assembly and framework thereof, particularly relate to a kind of LCD assembly that utilizes the elastic arm maintenance liquid crystal panel on the framework.

Background technology

In LCD assembly, when placing framework, can on framework, not form elastic mechanism usually because of slip causes the picture off-centring in order to ensure liquid crystal panel, slide arbitrarily to suppress liquid crystal panel.

With reference to figure 1a～1b, it shows a kind of known framework 10, forms a plurality of elastic mechanisms 11 on sidewall, though elastic effect is good, makes the complicated and easy-formation not of mould structure that this framework uses; If cross when thin, easily cause this adjacent area generation deformation even fracture with elastic mechanism 11 joining part wall thickness again; Otherwise the too thick elastic work of then losing of the part wall thickness that is connected is used.

With reference to figure 2a～2b, it shows another kind of known framework 20, on sidewall, form a plurality of elastic walls 21, when the assembling liquid crystal panel is in framework, if interference phenomenon is arranged, then liquid crystal panel needs elastic wall 21 is outwards squeezed, and its stressed fulcrum is both sides and framework connection place, elastic effect is not good, and assembles not easy-offtaking of back liquid crystal panel.

In addition, in TOHKEMY 2003-202550,2002-156632,2001-022291,2003-098510 communique, also proposed various framework, but its common shortcoming promptly is to make the mould structure complexity that framework is used, expense is expensive.

Embodiment

With reference to figure 3, LCD assembly 100 of the present invention comprises a framework 110 and a liquid crystal panel 120, its middle frame 110 in order to take in liquid crystal panel 120 and not the backlight assembly of icon in wherein, and liquid crystal panel 120 and not the backlight assembly of icon promptly constitute the display unit of LCD assembly 100.

With reference to figure 4a and Fig. 4 b, framework 110 is to be made of plastics, and have a first side wall 111, two elastic arms 112, a bottom surface 114, a supporting part 115 and one second sidewall 116, wherein the first side wall 111 has one first fen sidewall 111b and one second fen sidewall 111c, and at first fen sidewall 111b and all had an inner surface 111a (shown in Fig. 4 c) in one second minute on the sidewall 111c.

Each elastic arm 112 to be can being formed in the framework 110 with respect to the mode that the first side wall 111 moves, and is adjacent between first fen sidewall 111b and the second fen sidewall 111c, and is essentially an inverted T shape structure; Again, as shown in Fig. 4 c, each elastic arm 112 has a basal part 112a, a junction 112b, an and abutting part 112c, wherein basal part 112a is connected with first fen sidewall 111b and second fen sidewall 111c, and connecting portion 112b connects basal part 112a and abutting part 112c with for example circular shape, that is, the section of connecting portion 112b is for having the shape of similar S curve basically, so that the bearing surface 112c ' of abutting part 112c is positioned at the inside (with reference to figure 4d) of framework 110 than the inner surface 111a of the first side wall 111, that is, bearing surface 112c ' protrudes from the inner surface 111a of first fen sidewall 111b and second fen sidewall 111c, be positioned in the framework 110 when liquid crystal panel 120 whereby and during with elastic arm 112 butts, can be held in the framework 110 by the restoring force of elastic arm 112.

In addition, play abutting part 112c and first fen sidewall 111b of wall 112 and had a breach 113 in second minute between the sidewall 111c respectively, can move freely with respect to the first side wall 111 to guarantee elastic arm 112; Again, abutting part 112c upwards and to framework 110 inboards extends from basal part 112a.

Again, the wall thickness of the first side wall 111 is greater than the wall thickness of elastic arm 112, and elastic arm 112 and the first side wall 111 are to be formed in one.

Bottom surface 114 is in order to carrying light guide plate and diaphragm (reflecting piece, diffusion sheet and prismatic lens) 130 (with reference to figure 5a), and supporting part 115 is in order to bearing liquid crystal display panel 120; Again, second sidewall 116 is positioned at the opposite side of the first side wall 111, and also has a supporting part 115, so that liquid crystal panel 120 is flatly remained in the framework 110.

Liquid crystal panel 120 is arranged in the framework 110 in the mode with the bearing surface 112c ' butt of the abutting part 112c of elastic arm 112, and in the process of assembling, can push elastic arm 112 and bearing surface 112c ' is flushed with inner surface 111a.

In addition, in the present embodiment, framework 110 has the first side wall 111, supporting part 115 and bottom surface 114, and its section is ladder-type structure, but is not limited to this shown in Fig. 5 a; For example, Fig. 5 b shows another kind of framework 110 ', and it is for having supporting part 115 ', but does not have the T shape cross-section structure of bottom surface; Again, for example, Fig. 5 c shows another kind of framework 110 ", it is for having supporting part 115 ", but do not have the L shaped cross-section structure of bottom surface.

The formation of LCD assembly of the present invention below illustrates its assembling mode as mentioned above.

In the time will being positioned over liquid crystal panel 120 in the framework 110, at first make a side of liquid crystal panel 120 and the first side wall 111 butts of framework 110, as shown in Figure 6, this moment elastic arm 112 the bearing surface 112c ' of abutting part 112c be pushed into the inner surface 111a of the first side wall 111 and flush; Then, put into framework 110 downwards,, liquid crystal panel 120 is moved toward second sidewall, 116 directions, and the other end of liquid crystal panel 120 is kept by second sidewall 116 by the restoring force of elastic arm 112.

As above-mentioned, the characteristic that framework of the present invention can utilize the elastic arm tool to recover reaches functional that the restriction liquid crystal panel slides; In addition, because the design of the elastic arm of this framework is easy to moulding, its mould structure is comparatively simple and easy, generally speaking, by the moulding of elastic arm of the present invention, when forming framework with injection molded, except positive former, do not need to run again slide block or taper pin, technology is oversimplified.

Though the present invention discloses as above with preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; certainly can do various changes and retouching, so protection scope of the present invention should be with being as the criterion that claims scope is defined.
