DISPLAY DEVICE, ESPECIALLY REALIZING GHOST SAMPLING CIRCUIT WITH LOW POWER CONSUMPTION

摘要

PURPOSE: A display device is provided to suppress the generation of ghost due to aging drift delay by compensating an input sampling pulse by an external IC. CONSTITUTION: A panel has a gate line(13) in a row, and a signal line(12) in a column, and a pixel(11) arranged in a matrix on the cross part of both lines, and an image line(25) supplying an image signal. A vertical driving circuit(16) is arranged in the panel, and selects a row of a sequential pixel by being connected to the gate line. A plurality of sampling switches(23) are arranged in the panel so as to connect the signal line to the image line. A horizontal driving circuit(17) operates on the ground of a clock signal inputted from the external, and writes a sequential image signal to a pixel of a selected row by driving the plurality of sampling switches by generating sampling pulses in sequence. And a feedback circuit(50) detects the delay of the sampling pulse, and generates a feedback pulse considering the delay, and feedbacks to the external from the panel.
