LCD television

A liquid crystal display (LCD) apparatus displays an image by using the liquid crystal. The LCD display has various characteristics, for example, such as a thin thickness, a small volume and a lightweight compared with a cathode ray tube (CRT). Liquid crystal display (LCD) panels have developed as an alternative to cathode ray tubes (CRTs), offering the advantage of a thin profile and brilliant display. LCD panels have been used for a number of applications, including computer monitors and television displays. Since the volume of traditional cathode ray tube television (CRT TV) is large in addition to its problem of loosing originality of color and proportion, CRT TV is eliminated gradually. With the advancement of thin film transistor liquid crystal display (TFT LCD) technology, TFT LCD has gradually displaced the CRT display and become the mainstream of display technology. A liquid crystal display includes a liquid crystal display panel made up of two glass substrates with electrodes, a liquid crystal substance injected between them and a driver circuit, and controls the amount of transmitted light by changing the strength of the electric field between the electrodes so as to display a desired image. A liquid crystal display panel used in a television receiver includes a matrix array of horizontally oriented scanning electrodes and vertically oriented signal electrodes, the signal electrodes and scanning electrodes being disposed on mutually opposing substrates of the LCD panel. The liquid crystal television receiver converts video signals amplified at video amplifiers to digital signals by virtue of A/D converters and drives the liquid crystal display panel by the digital signal to permit images to be displayed on the liquid crystal display device.
