Abstract

The utility model relates to an improvement of the structure of a liquid crystal television. The liquid crystal television comprises a housing, a liquid crystal panel module, a power supplier, a signal processing circuit board and a connecting line thereof. The utility model is characterized in that all devices in the liquid crystal television and the connecting line of the signal processing circuit board are connected to one or multiple adapting joints, and the adapting joints are arranged on the proper positions in a sliding groove arranged on one side of the housing; in addition, the signal processing circuit board is arranged inside a control box, the surface of the control box is provided with connectors and the number and the positions of the connectors correspond to the number of the positions of the adapting joints. Thus, the control box can be inserted into the sliding groove of the housing in a sliding insertion mode so that the connectors of the control box are electrically switched into conduction with the adapting joints in the sliding slot and a separated design is convenient in maintenance or product upgrade.

Description

The improvement of liquid crystal television structure

Technical field

The utility model is relevant " improvement of liquid crystal television structure ", refers to the separate type design of a kind of relevant LCD TV internal connection line road and signal processing circuit board thereof especially, is convenient to maintenance or carries out product up-gradation.

Background technology

Press, in recent years, because scientific and technological progress drives the change of whole overall situation, general family requires also more fastidious in the past for audiovisual entertainment, not only wish to have better, bigger image, and truer, three-dimensional sound effect, therefore, large-sized audio-visual products has just appearred on the market, as conventional television, plasma-screen television and LCD TV, but conventional television is the source that utilizes iconoscope to produce as its image, when the larger sized screen of needs, its iconoscope just must be bigger, relatively, will make the volume of television set integral body become big, therefore, in large-sized screen war, conventional television just slowly has been eliminated; Remaining is exactly general more common plasma-screen television and LCD TV, but, plasma-screen television still is some problem on image quality, main is because the characteristic of its pixel, because electricity slurry pixel need lean on the electric current can be shinny, so it be not bright be exactly not work, and not between bright and stage that do not work, thereby use a kind of code pulse adjusting method (pulse code modulation that cries; PCM) method is controlled brightness, light the pixel that those these quilts are lighted exactly, and want hypographous place, just too often do not light that pixel partly, utilize vision to infer the equalization point that a time automatically and produce the effect of different brightness, but, the problem that other are but arranged, during as too close panel, beating of screen can make the people feel under the weather, and its screen has branding equally, is exactly the aging problem of pixel, be exactly that manufacturing cost is too high at last, its control element expending when producing is excessive; At last, can be exactly large-sized LCD TV relatively for what masses accepted, generally, liquid crystal is also more cheap than plasma-screen television, and with image quality, liquid crystal is also better than the brightness of CRT monitor, and liquid crystal pixel can not beated yet, therefore, LCD TV has very good image stability, that is to say, you can closely view and admire, need not fear that also eyes can be tired, and, its brightness is very good, image is also very sharp keen and more do not brand problem, LCD TV generally is to utilize aqueous crystal luminous principle of getting married under the effect of voltage, its aqueous crystal of forming screen has red, green, blue three kinds of primary colours, they are arranged in a certain order, stimulate these aqueous crystal by voltage, just can present different colors, collocation by different proportion can present Protean color, see also Fig. 1, LCD TV a has comprised housing a1, liquid crystal panel module a2, power supply unit a3, the circuit board a4 of signal processing and connecting line a5 thereof, the circuit board a4 of its signal processing has the function of image processing, during general the assembling, all be that liquid crystal panel module a2 is installed in housing a1 the place ahead, power supply unit a3, the circuit board a4 of signal processing is installed in housing a1 inside (21 " following TV power supply supply plug-in), and is therefore; when LCD TV a needs repairing or carry out the work of product up-gradation; all entire machine must be carried to maintenace point inconvenient completely, so be necessary to be improved.

The utility model content

The utility model creator has the shortcoming of the above-mentioned known configuration of prison, thus study intensively, and long-pending individual is engaged in the many years of experience of this cause, designs a kind of brand-new " improvement of liquid crystal television structure " eventually.

Main purpose of the present utility model aims to provide the liquid crystal television structure of a kind of housing and control circuit board separate design, can be convenient to maintenance or carry out product up-gradation.

For reaching above-mentioned purpose, the utility model " liquid crystal television structure improvement ", it mainly is to improve at the circuit board of housing, signal processing and connecting line thereof, at first, with LCD TV inner all be connected on one or several adapters with the connecting line of signal processing circuit board, and this adapter is to be installed in the interior appropriate location of housing one sideslip groove; In addition, the circuit board of signal processing is installed in the control box, and is provided with the connector of corresponding above-mentioned adapter number and position at control box.

When using according to above-mentioned structure, be directly to be fixed on control box in the chute of housing side in the mode that slides insertion, the connector of its control box and the adapter in the chute are conducted mutually, its circuit board of being responsible for signal processing function just can produce conducting with internal connection line, just can make the LCD TV regular event; Run into maintenance or when carrying out product up-gradation, deliver to special maintenace point and keep in repair or carry out product up-gradation as long as control box pulled down, the trouble in the time of not only can removing carrying from, and dismounting is also quite convenient.

Description of drawings

Structure of the present utility model, device and feature thereof are lifted a preferable possible embodiments and a conjunction with figs. and are described in detail as follows, wherein:

Fig. 1 is the three-dimensional structure diagram of known LCD TV;

Fig. 2 is a three-dimensional structure diagram of the present utility model;

Fig. 3 is an assembled sectional view of the present utility model.

Embodiment

The Fig. 2, shown in Figure 3 that please arrange in pairs or groups, " improvement of liquid crystal television structure " of the present utility model, it mainly is to improve at housing 10, LCD TV 1 connecting line 20 and signal processing circuit board 30 thereof, at first:

The inner all connecting lines 20 of LCD TV 1 are connected on one or several adapters 21, and this adapter 21 is the appropriate locations that are installed in the housing 10 1 sideslip grooves 11; In addition signal processing circuit board 30 is installed in the control box 31, and makes the circuit board 30 of above-mentioned signal processing be provided with the connector 32 of corresponding adapter 21 numbers, and its connector 32 is the positions that are arranged at adapters 21 in the corresponding chute 11 of control box 31 1 sides.

During use, be directly to be fixed on control box 31 in the chute 11 of housing 10 sides in the mode that slides insertion, the connector 32 of its control box 31 and the adapter 21 in the chute 11 are conducted mutually, the circuit board 30 of its signal processing just can produce conducting with connecting line 20, just can make LCD TV 1 regular event.
