Title:
【発明の名称】電界放出型表示素子およびその駆動方法
Document Type and Number:
Japanese Patent JP3134772
Kind Code:
B2
Abstract:
A field emission type display device capable of preventing a variation in luminance of the display device due to a variation in ambient temperature. A resistive layer is formed on cathode electrodes arranged in a display region and conical emitters are arranged on the resistive layer. The resistive layer is made of a semiconductor material, resulting in being varied in resistance depending on a temperature. A monitor resistive pattern made of the same material as the resistive layer is arranged so as to measure the resistance variation in the form of a voltage variation through an OP amplifier 11, which is then fed to the control circuit. The control circuit controls a gate voltage depending on the resistance to prevent a variation in luminance of the display device.
