Title:
液晶表示装置の駆動方法
Document Type and Number:
Japanese Patent JP4491632
Kind Code:
B2
Abstract:
A liquid crystal display includes an electro-luminescence portion which has electro-luminescence elements and a liquid crystal portion which has liquid crystal layer, scanning electrodes and signal electrodes and controls the transmittance of light emitted by the electro-luminescence elements. First, scanning pulses are applied in sequence to the scanning electrodes. Next, a gradation signal are applied associated with image data to the signal electrodes. Then, the electro-luminescence portion is allowed to emit light of a plurality of colors at the same time in pixels after transmissivity of the liquid crystal layers in the pixels reaches a predetermined value. The pixels are located at the intersections between a scanning electrode to which the scanning pulse is applied and the signal electrodes to which the gradation signal is applied.
