Liquid crystal display device and method for driving the same

摘要

Discussed are an LCD device and a method of driving the same in which, by decreasing the number of lines of a PCB, the manufacturing cost is saved, and the influence of noise is reduced.

主权项

1. A liquid crystal display (LCD) device, comprising:
a liquid crystal panel; a gate driver provided in an inactive area of the liquid crystal panel; and a printed circuit board (PCB) including:
a connector configured to receive low voltage differential signals (LVDSs) including image signals and a control signal,a timing controller merged integrated circuit (TMIC) including a timing controller and a first data driver, wherein the timing controller and the first data driver are merged within the TMIC,a plurality of second data drivers that are driven with packet data supplied from the TMIC,a power supply connected to the TMIC and the plurality of second data drivers,an erasable programmable read-only memory (EEPROM) to store a control signal for driving the TMIC and controlling gamma voltages,first lines connected between the timing controller of the TMIC and the connector in the PCB, andsecond lines independently connected between each of the plurality of second data drivers and the timing controller of the TMIC in the PCB,wherein the connector, the TMIC, the power supply, the EEPROM, the first lines, the second lines, and the plurality of second data drivers are mounted on the PCB, wherein the TMIC is configured to convert the image signals and the control signal in the LVDSs received via the first lines into the packet data and output the packet data to the plurality of second data drivers via the second lines, wherein the packet data includes a control signal for controlling each of the plurality of second data drivers, packet gamma data for generating the gamma voltages, and RGB image data, and wherein the PCB is a multi-layer board (MLB) PCB including the first lines and the second lines.
