Abstract
The utility model relates to the field of video players, in particular to a liquid crystal display television with touch buttons, wherein the control buttons are soft-touch buttons which comprise a button circuit board and a plurality of touch button areas installed on the button circuit board; and the button circuit board is electrically connected with the control circuit of the liquid crystal display television body. The television adopts touch buttons to replace the traditional mechanical buttons, thus leading the control on the television to be more reliable and sensitive and the service life to be longer.
Description
[technical field]
The utility model relates to a kind of video player field, specifically refers to a kind of touch controlled key formula LCD TV.
[background technology]
The button of existing television set is made up of three parts usually, i.e. button circuit board, mechanical key and injection moulding key.These mechanical keys are peripheral hardwares and protrude in the casing surface all generally; be easy to be subjected to external force to wear and tear; also can cause negative influence to complete machine handsome in appearance; also there are some LCD TV an over cap to be set and cover these mechanical keys, also operate inconvenience but can increase manufacturing cost like this at the casing face.And the stuck irrecoverable fault in back is pressed by traditional mechanical key regular meeting, and working life is shorter, can lose reliability and sensitivity after working long hours.
[utility model content]
The utility model purpose is to solve the available liquid crystal TV owing to there is the problem of poor reliability in the employing mechanical key, and a kind of touch controlled key formula LCD TV is provided.
The utility model touch controlled key formula LCD TV, comprise the LCD TV body, accommodate the casing of LCD TV body and be arranged on operating key on the casing face, wherein said operating key is for touching button, touches button and comprises button circuit board and be installed in a plurality of touch keypads on the button circuit board; The control circuit of described button circuit board and LCD TV body is electrically connected.
Preferably, described casing is provided with the pit of settling button circuit board, and pit is provided with cosmetic sheet lid and is connected on the pit, and in the casing flush.
Described cosmetic sheet is provided with and each operating key function corresponding character or pattern.
One end ground connection of described operating key, the other end is electrically connected the input of the microprocessor of button circuit board.
Described cosmetic sheet is provided with transparent area.
A kind of touch controlled key formula LCD TV of the present utility model, described operating key be for touching button, touches button and comprise button circuit board and be installed in a plurality of touch keypads on the button circuit board; The control circuit of described button circuit board and LCD TV body is electrically connected.Adopt touch controlled key to replace traditional mechanical key, the control television set that makes is reliable more sensitive, and working life is longer.

Description of drawings]
Fig. 1 is the floor map of the utility model LCD TV;
Fig. 2 is the circuit theory diagrams of button circuit board of the present utility model.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the floor map of the utility model LCD TV, it comprises LCD TV body 10, accommodate the casing 11 of LCD TV body and be arranged on operating key on the casing face, wherein said operating key 13 is arranged on the fore shell bottom of casing 11 for touching button, just display screen 12 below;
Described operating key 13 is for touching button 14, touches button 14 and comprises button circuit board and be installed in a plurality of touch keypads on the button circuit board; Casing is provided with the pit of settling button circuit board, and pit is provided with a cosmetic sheet 15 lids and is connected on the pit, and in the casing flush, described cosmetic sheet 15 is provided with and each operating key function corresponding character or pattern, is convenient to user's operation; During operation, each operating key 13 of user's finger touches, then the LCD TV body is realized function corresponding.
The control circuit of described button circuit board and LCD TV body 10 is electrically connected, and the two ends of operating key are flexible cord, and by flexible cord one end ground connection, the other end is electrically connected the input of the microprocessor of button circuit board.
In addition, cosmetic sheet 15 is provided with transparent area, plays a part to have attractive in appearance to integral body.
As shown in Figure 2, described each operating key abstract regard each switch as, seven XS611 model switches as shown in FIG., it is that with traditional difference its conducting resistance is different.The offresistance infinity of conventional switch, conducting resistance approach zero ohm, and touch the difference of button on manufacture craft, and its conducting resistance can not be zero ohm, is generally 1.5K ohm at present between 3K ohm.In the present embodiment, adopt the I/O interrupt mode to judge the state of operating key, I/O is in high level when idle, and then corresponding I/O becomes low level after touched.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
