LCD module simple point to say that the screen + backlight components. LCD TV display unit is the LCD module, its position is equivalent to CRT in the picture tube. Other parts include power circuit, signal processing circuit, etc., of course, what the shell. Modules are mainly divided into the screen and backlight components. The two part is assembled together, but it is independent of each other.

LCD display is the principle of the backlight component of a uniform surface light, light through the LCD screen to our eyes. The role of the screen is to display the image by processing the light. The two part contains a lot of components, here not elaborate. The best technology is SHARP, followed by Samsung SONY. (company official website: http://www.ddjmlcm.com/Cn/Index-215737.html)

In the display technology is to high clear, low electromagnetic radiation, low consumption and small volume, etc.. Although, CRT (cathode ray tube) display technology is becoming more and more mature

The display quality of the picture is also getting better, but its volume and radiation problems are still inevitable. Therefore, the LCD display with its small size, weight

Lightweight, no radiation, and other features to speed up the pace of the replacement of the traditional CRT display, but also by many people as the CRT terminator. Let's talk about the working principle of the LCD display.

LCD module is the most important material is liquid crystal, it is a rule of the organic compound, is a kind of material between the solid and liquid, the general use of the

The sub array is the most suitable for making nematic thin cylindrical liquid crystal display of liquid crystal display. The physical characteristics of the liquid crystal are: when the power is on, the molecular arrangement of the order, making the light easy to pass;

Electricity when the molecular arrangement of chaos, to prevent the light through. Let the liquid crystal molecules, such as gate - like barrier or let the light penetrate. Most liquid crystals are organic compounds, which are composed of long rods.

Constitute. In the natural state, the long axis of the rod molecules is roughly parallel. The liquid crystal into a well - processing of the slotted plane, the liquid crystal molecules will be arranged along the groove, so if those

The groove is very parallel, then the molecules will be exactly parallel. Technically speaking, the liquid crystal panel contains two very fine sodium free glass material, called Substrates, in the middle.

A layer of liquid crystal. When the beam passes through the liquid crystal, the liquid crystal itself will stand or twist the shape of the irregular shape, and thus block or make the beam pass through. (company official website: http://www.ddjmlcm.com/Cn/Index-215737.html)

From the perspective of the structure of the liquid crystal display, whether it is a notebook computer or a desktop system, the use of LCD display is composed of different parts of the layered structure. LCD consists of two pieces of glass plate

The composition, thickness of about 1mm, is separated by a 5 m uniform spaced from a liquid crystal material. Because the liquid crystal material itself does not emit light, so in the display on both sides are provided with the lamp as the light source

And on the back of the liquid crystal display screen has a backlight plate (or uniform plate) and a reflecting film, backlight plate is composed of a fluorescent substance can emit light, its role is mainly to provide a uniform background

Light source. The light emitted by the backlight is entered into the liquid crystal layer containing thousands of liquid crystal droplets after passing through the first layer of polarization filter layer. Droplets in the liquid crystal layer are contained in small cells

Structure, one or more cells that form a pixel on the screen. Between the glass plate and the liquid crystal material is a transparent electrode, the electrode is divided into rows and columns, rows and columns of the cross points,

By changing the voltage and changing the optical rotation state, the role of the liquid crystal material is similar to a small light valve. The control circuit and the driving circuit of the liquid crystal material are peripheral. When

When an electric field is generated in a LCD, the liquid crystal molecules will be distorted, and the light rays passing through them have a regular refraction, and then pass through the filter layer of the second layer.

Show.

Liquid crystal display technology also has weaknesses and technical bottlenecks, compared with the CRT display brightness, image uniformity, visual angle and reaction time are obvious gaps. Among them

Time and visual angle depend on the quality of LCD panels, and the uniformity of the picture is very much related to the auxiliary optical module. The brightness of the LCD display mainly depends on the backlight. (company official website: http://www.ddjmlcm.com/Cn/Index-215737.html)

For liquid crystal displays, the brightness is often related to his back light source. The more light the back light source, the brightness of the LCD display will be improved. And in the early liquid crystal display

In the device, because only the use of 2 cold light source, often resulting in uneven brightness and other phenomena, while the brightness is not satisfactory. Until the end of the use of 4 cold light source tube products

And then there's no small improvement.

The signal response time is the LCD cell response delay. Actually refers to the liquid crystal cell from a molecular arrangement of the state into another molecular arrangement

Need time, response time, the smaller the better, it reflects the speed of response to input signals of the liquid crystal display pixel, the pixel by the dark turn bright or dark by the light switch speed. (http://www.ddjmlcm.com/Cn/Index-215737.html) response

The smaller the time, the user will not appear when watching the motion picture. Some manufacturers will reduce the conductivity of the liquid crystal in the body to achieve rapid response,

But its color is full
