The following is part of the LCD TV with a brief explanation for each function:
1. Front Panel Display
When compared with CRT TV then the Front Panel LCD Display is a Flat panel of his generally currently used mammal TFT LCD. Although many were using Plasma technology.
On the front panel display block is the Backlight to produce white light across the surface of the LCD. Diffuser that serve as filters, Polariser, backlight Back arrangement of TFT LCD, RGB Filters and Polariser Front.
The workings of the Front panel LCD display, more or less at the time of the LCD gets voltage then the molecule is a molecule crystals will be composed into horizontal so that the light from the translucent layers of the backlight can be front LCD. This could happen because the LCD is very crystal molecules between solid and liquid.
2. Backlight and Inverter
Backlight is part which also includes Front Panel Display. Inverter here is not part of the main power supply. We often see on the edge of the LCD if we overhaul will look like a small transformer transformer, that is the inverter. Its function is to change the voltage DC 12V into 1000 – 4000 VAC.
Because the display requires a voltage that is large enough so that it can produce a bright light. The Backlight itself is currently commonly used with type LED lamps.
3. TCON Board/FRC Matrix
The TCON is also a unity with The LCD Panel display, backlight and inverter. We know on CRT TV image is generated when electrons are controlled by Yoke def. CRT tubes fired at the luminous colours of so. The difference with this light the LCD is generated from every pixel on the LCD.
There are thousands of pixels/pixel LCD and every element has one transistor to be able to turn on/off the pixel.
The lighting of this pixel is controlled by a module or TCON Board FRC module is determined, the transistor which is active or inactive.
On the modules provided a TCON connector that has a pin that much to be connected to the main board. This module is usually closed aluminium to avoid interference.
4. Main PCB/Main Board
The function of the module in the main board is to process all signals that either an audio or video that is captured by a tuner. Still remember how to work the TV not CRT, where images are processed by the main IC got fed into a series of RGB Video amplifier for later given directly into the tube CRT.
In contrast to the workings of TV CRT, LCD there is a process to convert analog signal video signal into digital form – due to the presence of thousands of pixel transistor controlled by modules TCON.
On the main module includes tuner, analog to digital converter, mikrokontrol, determine which input is used and a variety of other TV functions.
Because there are still many parts of the LCD TV that has not been described, then this article will continue to section 2, ... may be useful
