P‐156: Distinguished Student Poster: Image Flickering Reduction by Dimer and Polymer Stabilization in ADS Liquid Crystal Display

Abstract

When a LCD display static images, power consumption can be reduced by employing a low driving frequency. However, when the driving frequency is decreased, there is a problem that the brightness of the display may change with time, a phenomenon known as flickering. One factor responsible for the flickering issue is flexoelectric effect. We show that flickering in ADvanced Super Dimension Switch (ADS) LCD can be significantly reduced by doping a liquid crystal dimer and using polymer stabilization. We demonstrated that 2 Hz driving frequency can be used to display static images.

Ultralow Power Consumption Liquid Crystal Display Retaining Superior Image Qualities

“…Flexoelectricity can be used for the reduction of power consumption in liquid crystal displays (LCDs). [2,3,[12][13][14][15][16][4][5][6][7][8][9][10][11] Unlike the piezoelectric effect results in a linear coupling between mechanical deformation and electric polarization in dielectric systems, flexoelectricity arises in mesogenic liquid crystal (LC) systems according to the spatial strain gradient. [17][18][19][20][21][22] A symmetric stress induces a symmetric response, as Curie's principle suggests.…”
