Disclosed is a display device that includes a display panel, a guide frame configured to support the display panel, a plurality of fixers arranged between the display panel and the guide frame and include an accommodating part, a cover member inserted into the accommodating part of each fixer and configured to fix the display panel to the guide frame together with the plurality of fixers, and a pad disposed between the display panel and the guide frame and configured to prevent penetration of a foreign material.

Display device

A liquid crystal display device includes a liquid crystal panel, a driver that drives the liquid crystal panel, an input unit that inputs an option signal from outside the liquid crystal device, a controller that controls the driver and performs an option function corresponding to the option signal, and a buffer disposed between the input unit and the controller that removes an excitation voltage from the option signal output from the input unit.

Liquid crystal display device and method of controlling the same for removing excitation voltage

A circuit that drives a liquid crystal display device, includes an EEPROM having control data that over-drives and provides adaptive brightness intensification, the control data in the EEPROM is protected so as to secure reliability of the EEPROM. The circuit includes a master for over-driving and adaptive brightness intensification, a slave for providing control data to the master, a connector for connecting external writing equipment with terminals on the slave to write the control data into the slave, and an internal power supply of a liquid crystal module that applies an internal supply voltage to the slave. A write control terminal on the slave is grounded in a write mode, and connected to the internal power supply of the liquid crystal module in a liquid crystal module drive mode.
