US 6654078 B1
1. A panel for a mobile terminal, comprising:
a liquid crystal display (LCD) having a front and a back cover, one of said front and back cover having a side surface that extends generally perpendicular to a plane of the LCD and that has a recess therein;
a frame in which said LCD is mounted and that has a side wall extending generally perpendicular to the plane of the LCD, said side surface of said LCD being interior to and spaced from said sidewall of said frame, said frame having in a space between said side surface and said sidewall a free-standing flexible claw longitudinally extending generally perpendicular to the plane of the LCD directly from an interior surface of said frame that is generally parallel to the plane of the LCD,
a distal end of said free-standing flexible claw having a sloped projection with a flat bottom that is generally parallel to the plane of the LCD and that engages said recess to hold said LCD in said frame.
2. The panel of claim 1, comprising a plurality of pairs of said recess and said flexible claw.
The above side mount type liquid crystal module has the following disadvantage. FIG. 3 is a fragmentary cross sectional elevation view illustrative of a mounting structure of a side mount type liquid crystal module to an outside frame. A liquid crystal module 1 is engaged within an outside frame 7 and a bottom frame 5, wherein a distance “d” is present between an inside wall of the outside frame 7 and a side face of a back-light portion 8 of the liquid crystal module 1, so that a screw 6 is driven into screw holes to penetrate the bottom frame 5 and the outside frame 7 and enters into the side portion of the liquid crystal module 1. The distance “d” is necessary as a margin for driving the screw 6. This distance “d” as the screw margin results in widening the liquid crystal module 1.
Further, a space defined in the distance “d” is formed between the outside frame 7 and the back-light portion 8. This space or the distance “d” makes small a ratio in area of a display surface 1 a to the entire part of the liquid crystal module 1. The area of the liquid crystal module 1 is limited by the cover to which the liquid crystal module is mounted. Namely, the space or the distance “d” makes small a ratio in area of the display surface 1 a to the entire part of the cover.
Further, the screw 6 has a diameter “r”. The screw hole formation portion 4 extends in a thickness direction of the liquid crystal module 1. This screw hole formation portion 4 has margins “m1” and “m2”. A size of the screw hole formation portion 4 is “D” which is the sum of the diameter “r” of the screw 6 and the margins “m1” and “m2”. Those margins “m1” and “m2” make it difficult to further reduce the thickness of the liquid crystal module 1.
The term “structural frame” means to include both a bottom plate portion of the cover, wherein the back face of the liquid crystal module faces to the bottom plate portion of the cover when the liquid crystal module is fitted into the cover, and an outside frame which comes together with the side faces of the liquid crystal module.
The term “structural frame” means to include both a bottom plate portion of the cover, wherein the back face of the display module faces to the bottom plate portion of the cover when the display module is fitted into the cover, and an outside frame which comes together with the side faces of the display module.
A second embodiment according to the present invention will be described in detail with reference to the drawings. FIG. 9 is a perspective view illustrative of a liquid crystal module mounting structure for mounting a liquid crystal module to a structural frame of a cover of a personal computer in a second embodiment in accordance with the present invention. In this embodiment, a pair of right and left metal reinforcement members 50 are provided both for increasing the mechanical strength of the cover accommodating the liquid crystal module 10 and for mounting the liquid crystal module 10
A liquid crystal module 10 is mounted to a pair of right and left metal reinforcement members 50. The right and left metal reinforcement members 50 are attached to a bottom plate 20 of a cover of a personal computer. An outside frame 30 is attached through the right and left metal reinforcement members 50 to the bottom plate 20. The bottom plate 20 and the outside frame 30 are made of a plastic. The right and left metal reinforcement members 50 are made of a metal. The bottom plate 20 faces to the back face of the liquid crystal module 10. The liquid crystal module 10 has a display face 10 a which is opposite to the back face. The liquid crystal module 10 is disposed between the bottom plate 20 and the outside frame 30 of the cover. The liquid crystal module 10 is mounted to the right and left metal reinforcement members 50 by the following novel liquid crystal mounting structure. The outside frame 30 is attached through the right and left metal reinforcement members 50 to the bottom plate 20 of the cover by the following attachment tools.
The engagement structure shown in FIG. 12 may further be modified as follows. FIG. 14 is a fragmentary cross sectional elevation view illustrative of another modified engagement structure between the projecting portions provided on the liquid crystal module and the guide grooves provided on the bottom plate. The liquid crystal module 10 has right and left sides, each of which is provided with two projecting portions 16 as engagement parts. The two projecting portions 16 arc distanced from each other and are positioned close to the opposite corners at opposite ends of each of the right and left sides of the liquid crystal module 10. The bottom plate 20 has right and left rims which have inside right and left rim faces 20 b and 20 c. Each of the inside right and left rim faces 20 b and 20 c has two guide grooves 26 at corresponding positions to the above two projecting portions 16, so that the four guide grooves 26 are engaged with the four projecting portions 16. Each of the guide grooves 26 comprises a first guide groove portion 26 a and a second glide groove portion 26 b connected with the first guide groove portion 26 a. The first guide groove portion 26 a extends in the thickness direction of the bottom plate 20. The second guide groove portion 26 b extends in a longitudinal direction of the right and left rim portions of the bottom plate 20. Namely, the second guide groove portion 26 b extends perpendicular to the first guide groove portion 26 a, so as to form a L-shape of the guide groove 26. Further, each of the guide grooves 26 has elastic members 26 c to form a pinch in the second guide groove portion 26 b in the vicinity of the corner of the L-shape of the guide groove 26. When the liquid crystal module 10 is pushed into the bottom plate 20, then the projecting portions 16 are inserted through the first guide groove portion 26 a of the guide groove 26. Further the liquid crystal module 10 slides onto the bottom plate 20, so that the projecting portions 16 are moved along the second guide groove portion 26 b of the guide groove 26, wherein the projecting portions 16 are made into contact with the narrowed portions of the elastic members 26 c whereby the narrowed portions of the elastic members 26 c are opened and widen to allow the projecting portions 16 to enter into the second guide groove portion 26 b of the guide groove 26. The liquid crystal module 10 slides onto the bottom plate 20 until the projecting portions 16 are made into contact with the ends of the elastic members 26 c accommodated in the second guide groove portion 26 b of the guide groove 26, and further the opened elastic members 26 c are returned to the original form to have the narrowed or pinched portions, whereby the projecting portions 16 are engaged with the guide groove 26 and the narrowed or pinched portions of the elastic members 26 c prevent the projecting portions 16 from returning to the first guide groove portion 26 a.
The engagement structure shown in FIG. 12 may further be modified as follows. FIG. 15 is a fragmentary cross sectional elevation view illustrative of still another modified engagement structure between the L-shaped projecting pieces provided on the liquid crystal module and a box-shaped engagement portions provided on the bottom plate. FIG. 16 is a fragmentary cross sectional elevation view illustrative of an engagement structure of FIG. 15. The liquid crystal module 10 has right and left sides, each of which is provided with two L-shaped projecting pieces 19 as engagement parts. The two L-shaped projecting pieces 19 are distanced from each other and are positioned close to the opposite corners at opposite ends of each of the right and left sides of the liquid crystal module 10. Each of the L-shaped projecting pieces 19 has a projected front portion which is parallel to the display surface of the liquid crystal module. The projected front portion of the each of the L-shaped projecting pieces 19 has a convex portion 19a. The bottom plate 20 has four box-shaped engagement parts 28 at corresponding positions to the above four L-shaped projecting pieces 19. Each of the box-shaped engagement parts 28 has a square-shaped opening portion 28 a, a guide groove 28 b connected with the square-shaped opening portion 28 a, a holding wall 28 c adjacent to the square-shaped opening portion 28 a and to the guide groove 28 b, and a hole 28 d formed in the holding wall 28 c. The square-shaped opening portion 28 a has a corresponding size to the projected front portion of the L-shaped projecting piece 19 so as to allow the projected front portion of the L-shaped projecting piece 19 to enter through the square-shaped opening portion 28 a into the box-shaped engagement part 28. The L-shaped projecting piece 19 comprises a projecting base portion and the projected front portion which is supported by the projecting base portion. The projecting base portion extends in the thickness direction of the liquid crystal module 10, so that the projecting base portion is vertical to the projected front portion. The guide groove 28 b has such a width as allowing a projecting base portion of the L-shaped projecting piece 19 to move along the guide groove 28 b when the liquid crystal module 10 slides onto the bottom plate 20 after the projected front portion of the L-shaped projecting piece 19 has entered through the square-shaped opening portion 28 a into the box-shaped engagement part 28. As the projecting base portion of the L-shaped projecting piece 19 moves along the guide groove 28 b by moving the liquid crystal module 10 to slide onto the bottom plate 20, the projected front portion of the L-shaped projecting piece 19 comes corresponding in position to an inside face of the holding wall 28 c of the box-shaped engagement part 28, whereby the convex portion 19 a on the projected front portion is snapped into the hole 28 d of the box-shaped engagement part 28, so that the four box-shaped engagement parts 28 are engaged with the four L-shaped projecting pieces 19.
