Neuron Based Driving Circuit for Flat Panel Display

Ultra-high pixel is the trends of flat panel display, while conventional row and column driving circuit would cause high fabrication cost and low effective luminous area. In this letter, neuromorphic device is applied to the flat panel display driving circuit for the first time. A neuron based display driving circuit is developed, which reduces 3/4 area of row circuit, for instance, 1024 scan lines are able to replace 4096 scan lines in a 4 K flat panel display screen.

I. Introduction

Ultra-high pixel is one of the inevitable trends of flat panel display [1]–[3]. Row and column circuit is the driving circuit of flat panel displays, which controls light-emitting pixel through the designed waveform sequence [4], [5]. Usually, row circuit is used as scan line and column is functioned as data line. When the row and column circuit are selected at the same time, light-emitting pixel will be lighted. With the increase of the density of light-emitting pixels, a large area on display chip is used as driving circuit, resulting in the high fabrication cost and low effective luminous area. Therefore, a simplified paradigm with reduced area of driving circuit is urgently required for flat panel displays.
