DISPLAY DEVICE INCLUDING FLEXIBLE PRINTED CIRCUIT BOARD

摘要

PURPOSE: A display device including a flexible print circuit board is provided to reduce the rate of the noise of first ground voltage reflected in a second ground voltage by minimizing a connection area of first and second ground voltages. CONSTITUTION: A display panel(10) comprises a pixel array. A module block comprises a plurality of circuits. A plurality of the circuits outputs a driving signal. A system block comprises a power circuit substrate(150). The power circuit substrate supplies voltage to a plurality of the circuits of the module block. A flexible PCB(FP) comprises a first and a second ground power sources(GND1, GND2). The first ground power source is connected to the power circuit substrate. The second ground power source is connected to the multiple circuits of the module block.
