Description

LCD TV Structure Improvement

technical field

The utility model relates to "improvement of liquid crystal TV structure", especially a separate design of internal connection circuit and signal processing circuit board of liquid crystal TV, which is convenient for maintenance or product upgrade.

Background technique

By the way, in recent years, due to the changes in the overall environment driven by technological progress, ordinary families have become more picky about audio-visual entertainment requirements than before. They not only hope to have better and larger images, but also more realistic and three-dimensional sound effects. Therefore, , large-size audio-visual products have appeared on the market, such as traditional TVs, plasma TVs and LCD TVs, but traditional TVs use image tubes as the source of their images. When larger-sized screens are required, the image The tube has to be bigger, relatively, it will make the overall size of the TV larger, so in the large-size screen war, the traditional TV is gradually eliminated; what is left is the more common TV Plasma TV and LCD TV, however, there are still some problems in the image quality of plasma TV, mainly because of the characteristics of its pixels, because plasma pixels need to rely on electric current to light up, so it is either bright or not bright , and there is no stage between on and off, so a method called pulse code modulation (PCM) is used to control the brightness, which is to light up the pixels that should be lit, but there must be shadows In some places, do not light up that part of the pixels too often, and use vision to automatically guess a time average point to produce different brightness effects. However, there are other problems, such as when the screen is too close to the panel. Jumping will make people feel uncomfortable, and the screen also has branding, which is the problem of pixel aging. Finally, the manufacturing cost is too high, and the cost of its control components is too large during production; finally, the more acceptable to the public is Large-size LCD TVs, generally speaking, LCDs are cheaper than plasma TVs, and in terms of image quality, LCDs are brighter than CRT monitors, and LCD pixels will not jump. Therefore, LCD TVs It has great image stabilization, that is to say, you can watch it at close range without fear of eye fatigue. Moreover, its brightness is great, the image is very sharp and there is no problem of burn-in. LCD TVs generally use liquid crystals The principle of luminescent imaging under the action of voltage, the liquid crystals that make up the screen have three primary colors of red, green, and blue. They are arranged in a certain order, and these liquid crystals can be stimulated by voltage to present different colors. The combination of different proportions can present ever-changing colors. Please refer to Figure 1. LCD TV a includes housing a1, LCD panel module a2, power supply a3, circuit board a4 for signal processing and its connecting wire a5. The circuit board a4 for signal processing has the function of image processing. Generally, when assembling, the LCD panel module a2 is installed in front of the case a1, and the power supply a3 and the circuit board a4 for signal processing are installed inside the case a1 (The TV power supply under 21” is plugged in). Therefore, when the LCD TV a needs to be repaired or upgraded, the whole machine must be transported to the repair point, which is very inconvenient, so it is necessary to improve it.

Utility model content

The inventor of the utility model has the shortcoming of above-mentioned known structure, so studies meticulously, and accumulates the many years experience that the individual is engaged in this career, finally designs a kind of brand-new " structure improvement of liquid crystal television ".

The main purpose of the utility model is to provide an LCD TV structure in which the casing and the control circuit board are separately designed, which can facilitate maintenance or product upgrades.

In order to achieve the above-mentioned purpose, the utility model "improvement of LCD TV structure" is mainly aimed at improving the shell, the connection wire of the LCD TV and the circuit board for signal processing. First, all the connections between the LCD TV and the signal processing circuit board The wires are connected to one or several adapters, so that the adapters are set at an appropriate position on the surface of the fixed groove at the rear of the housing; in addition, the circuit board responsible for signal processing is installed in the control box and set on the surface of the control box. There are connectors corresponding to the number and position of the above adapters.

When used according to the above structure, the control box is directly installed and fixed in the fixing groove at the rear of the housing, and the connector of the control box will be electrically connected with the adapter in the fixing groove, so that the signal processing circuit board is connected to the internal The normal operation of the LCD TV can be achieved by the conduction of the line; in case of maintenance or product upgrade, just remove the control box and send it to a special maintenance point for repair or product upgrade, which can not only save the trouble of handling Trouble, and disassembly is also quite convenient.

Description of drawings

The structure, device and features of the present utility model give a preferred feasible embodiment together with the accompanying drawings in detail as follows, wherein:

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

Fig. 2 is the three-dimensional structural diagram of the utility model;

Fig. 3 is a combined sectional view of the utility model.

Detailed ways

As shown in Figure 2 and Figure 3, the "improvement of LCD TV structure" of the present invention is mainly aimed at improving the casing 10, the connection line 20 of the LCD TV 1 and the circuit board 30 for signal processing. First:

Connect all the connecting wires 20 inside the LCD TV 1 to one or several adapters 21, and arrange the adapters 21 at an appropriate position on the surface of the solid groove 11 at the rear of the housing 10; in addition, the circuit board 30 responsible for signal processing Installed in a control box 31, and the control box 31 is provided with connectors 32 corresponding to the number of adapters 21, and the connectors 32 are arranged on the surface of the control box 31 corresponding to the positions of the adapters 21 on the fixing groove 11.

When in use, the control box 31 is directly installed and fixed in the fixing groove 11 at the rear of the housing 10, and the connector 32 of the control box 31 will be electrically connected with the adapter 21 in the fixing groove 11, so that the signal processing When the circuit board 30 is connected to the connection line 20, the LCD TV 1 can operate normally.

To sum up, the utility model "improved liquid crystal TV structure", its connecting circuit is installed inside the casing, and its circuit board responsible for signal processing is installed in a control box with a separate design, which can facilitate maintenance Or carry out product upgrades, and have the "practicability" and "progressiveness" of creation, so the applicant filed an application for a new type patent according to law.
