Abstract: An apparatus is disclosed for detecting error in a transfer system for transferring a substrate loaded upon fabricating of a liquid crystal display device of a flat panel display device. In an apparatus for detecting error of the transfer system, a test substrate includes reflective marks arranged symmetrically on both sides. An emitter generates light to radiate onto the transferring test substrate. A receiver receives light reflected from the reflective marks of the test substrate. A controller detects any error of the transfer system on the basis of the reflective times received by the receiver. A display displays any errors in the transfer system detected by the controller.

Abstract: An apparatus for detecting error of a transfer system that is adapted for detecting an error of a transfer system transferring a substrate loaded upon fabricating of a flat panel display device in a real time is disclosed. In the apparatus, an emitter generates a light and radiates the light into a transfer system. A receiver receives light reflected from the transfer system. A controller controls light radiation from the emitter, and measures the time such that a reflective light of the transfer system is received from an emitting point of the emitter to the receiver. The controller also detects a displacement of the transfer system using the measured time, a designated reference distance and a reference time. A display displays the displacement of the transfer system detected by the controller.

Abstract: A liquid crystal display device include a gamma a voltage controller. The gamma voltage controller includes a voltage-divider network of resistive elements and is part of a gamma voltage circuit, which also includes a programmable digital-to-analog converter. The output voltage signals from the programmable digital-to-analog converter are input to the gamma voltage controller for requisite voltage division. The voltage difference between any two voltage signals output from the gamma voltage controller (i.e., the gamma reference voltage signals) can be finely aligned by setting appropriate values for different resistive elements in the gamma voltage controller. This allows generation of gamma reference voltage signals whose voltages can be precisely controlled according to the T-V characteristics of a liquid crystal display panel in the liquid crystal display device.
