Patent ID: 7893902

Claim:
A liquid crystal display (LCD), comprising: a glass substrate comprising a display area; a plurality of driving integrated circuits (ICs) configured for providing image signals to the display area, each driving IC comprising a plurality of first reference voltage pins, a plurality of second reference voltage pins, a plurality of first voltage following pins, a plurality of second voltage following pins, and an operating voltage input pin; a plurality of first voltage change circuits respectively connected between the first reference voltage pins and the first voltage following pins, each first voltage change circuit configured for conducting a first reference voltage from the first reference voltage pin to the first voltage following pin, and configured to be burned by an external apparatus such that the first reference voltage is thereafter changed to a different first reference voltage by the first voltage change circuit; a plurality of second voltage change circuits respectively connected between the second reference voltage pins and the second voltage following pins, each second voltage change circuit configured for conducting a second reference voltage from the second reference voltage pin to the second voltage following pin, and configured to be burned by the external apparatus such that the second reference voltage is thereafter changed to a different second reference voltage by the second voltage change circuit; and a flexible printed circuit board (FPCB) connected to the glass substrate for providing operating voltages to the driving ICs.
