Abstract
The utility model discloses an ultra-thin durable liquid crystal display device. The ultra-thin durable liquid crystal display device comprises an LCD screen, a backlight source, a display panel, a driver chip and a flexible printed circuit board, wherein the LCD screen, the backlight source and the display panel are stacked in sequence, the flexible printed circuit board is fixed to the display panel and is connected with the driver chip, an extending portion which is used for being connected with an external control chip is arranged on the flexible printed circuit board, a plurality of longitudinal reinforcing ribs are arranged on one face, fixedly connected with the display panel, of the flexible printed circuit board, and a plurality of transverse reinforcing ribs are arranged on the extending portion of the flexible printed circuit board. According to the ultra-thin durable liquid crystal display device, due to the facts that the longitudinal reinforcing ribs are arranged on the face, fixedly connected with the display panel, of the flexible printed circuit board, and the transverse reinforcing ribs are arranged on the extending portion of the flexible printed circuit board, the frequency of the phenomena that welding legs of the backlight source loosen and contact is poor due to external force which is generated in the process of pulling operation such as folding operation and torsion operation when the ultra-thin durable liquid crystal display device is assembled is greatly reduced, and the ultra-thin structure of the ultra-thin durable liquid crystal display device is obtained.
Description
Technical field
The utility model relates to field of liquid crystal display, relates in particular to a kind of ultra-thin durable type liquid crystal indicator.
Background technology
Volume is frivolous, little, the advantage such as radiation is little takes up room because it has for liquid crystal indicator; occupied gradually the main flow that shows product; advance in the past few years more and more thinner to the requirement of product; therefore can adopt flexible PCB; but the flexible PCB leg that frequent meeting is pullled the action backlight because of crooked, folding etc. in the process of using becomes flexible, and causes the LED loose contact, has affected the serviceable life of backlight; and then can't realize the ultra-thin characteristic of liquid crystal indicator, demand that can't satisfying the market.
The utility model content
For the weak point existed in above-mentioned technology, the utility model provides the ultra-thin durable type liquid crystal indicator of little, the frivolous and long service life of a kind of volume, by being provided with on flexible PCB in length and breadth to reinforcement, greatly having alleviated folding, distortion etc. and pullled the impact of process external force on this device.
For achieving the above object, the utility model provides a kind of ultra-thin durable type liquid crystal indicator, comprises LCD screen, backlight, display panel, driving chip and flexible PCB; Described LCD screen, backlight and display panel stack gradually, described flexible PCB is fixed on display panel and with driving chip and is connected, described flexible PCB is provided with the extension for being connected with the external control chip, the fixing one side of described flexible PCB and display panel is provided with many walings, and the extension of described flexible PCB is provided with many cross reinforcings.
Wherein, described driving chip bonding is on display panel and drive the 128*64 dot matrix of LCD screen.
Wherein, described waling is the strip waling, and described cross reinforcing is the strip cross reinforcing.
Wherein, described flexible PCB is the L-type flexible PCB.
The beneficial effects of the utility model are: compared with prior art, the ultra-thin durable type liquid crystal indicator that the utility model provides, the fixing one side of flexible PCB and display panel is provided with waling, the extension of flexible PCB is provided with cross reinforcing, greatly alleviated that this device is folding in assembling process, distortion etc. pulls external force in process and causes the leg of backlight loosening, and the phenomenons such as loose contact, and then realize the ultrathin structure of display device.The utlity model has that compact conformation, volume are little, frivolous, the characteristics such as Stability Analysis of Structures and long service life.
The accompanying drawing explanation
The structural drawing that Fig. 1 is ultra-thin durable type liquid crystal indicator of the present utility model;
The structural drawing that Fig. 2 is flexible PCB in the utility model.
The main element symbol description is as follows:
10, LCD screen 11, backlight
12, display panel 13, driving chip
14, flexible PCB 15, waling
16, cross reinforcing
Embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1-2, the ultra-thin durable type liquid crystal indicator that the utility model provides, comprise LCD screen 10, backlight 11, display panel 12, drive chip 13 and flexible PCB 14; LCD screen 10, backlight 11 and display panel 12 stack gradually, flexible PCB 14 is fixed on display panel 12 and with driving chip 13 and is connected, flexible PCB 14 is provided with the extension for being connected with the external control chip, the fixing one side of flexible PCB 14 and display panel 12 is provided with many walings 15, and the extension of flexible PCB 14 is provided with many cross reinforcings 16.
Situation compared to prior art, the ultra-thin durable type liquid crystal indicator that the utility model provides, the fixing one side of flexible PCB 14 and display panel 12 is provided with waling 15, the extension of flexible PCB 14 is provided with cross reinforcing 16, greatly alleviated that this device is folding in assembling process, distortion etc. pulls external force in process and causes the leg of backlight 11 loosening, and the phenomenons such as loose contact, and then realize the ultrathin structure of display device.The utlity model has that compact conformation, volume are little, frivolous, the characteristics such as Stability Analysis of Structures and long service life.
In the present embodiment, drive chip 13 to be bundled on display panel 12 and drive LCD to shield 10 128*64 dot matrix.What this device adopted is the COG technology, and chip on glass, drive chip 13 directly to be bundled on glass, realize driving and control, and then realized the 128*64 dot matrix, the wide temperature low-power consumption that improves LCD screen 10 shows, can under the condition of not wasting resource, meet the display effect of product.
In the present embodiment, waling 15 is the strip waling, and cross reinforcing 16 is the strip cross reinforcing.Be that the two is all strip; be conducive to better improve the anti-property pullled; certainly; the shape of reinforcement is not limited to this, can also be wavy or zigzag, simultaneously; the length of these two kinds of reinforcements or width also can change according to the length and width of flexible PCB 14; if, to the shape of waling 15 or cross reinforcing 16 or the change of quantity, all belong to simple variation of the present utility model or conversion, fall into protection domain of the present utility model.
In the present embodiment, flexible PCB 14 is the L-type flexible PCB.To have changed the conventional flex circuits plate be bendability and be fixed on the little defect of area on display panel, because the conventional flex circuits plate Area comparison fixing with display panel is little and most of, mainly with the external control chip, be connected, there will be fretwork area too many, more easily make the signal lead of flexible PCB break down, and the utility model is designed to L-type by flexible PCB 14, only there is extension to be connected with the external control chip, improved the performance of the signal lead of this flexible PCB 14.
Above disclosed be only several specific embodiment of the present utility model, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
