Abstract
A liquid crystal display (LCD) and circuit architecture thereof are proposed. Power signal lines, data signal lines, and control signal lines are mounted on a printed circuit board (PCB) and a thin film substrate. The thin film substrate is connected to a LCD panel by using a COF bonding. These circuits can be transferred onto a conductive glass of the panel and subsequently onto source driver chips of the thin film substrate of the COF. Therefore, a position which needs the least time for power signal lines, data signal lines, and control signal lines to transmit to all of the circuits of the panel on the PCB can be calculated in order to achieve the best design.
