DISPLAY APPARATUS AND METHOD OF DRIVING A DISPLAY PANEL

摘要

A display apparatus includes a display panel that includes a liquid crystal layer, a first pixel having the liquid crystal layer with a first thickness, a second pixel having a color filter and the liquid crystal layer with a second thickness. The display apparatus also includes a data generating unit configured to generate a first image signal corresponding to the first pixel and a second image signal corresponding to the second pixel in response to an input image signal, a data converting unit configured to convert a gradation value of the first image signal into a conversion gradation value of the first image signal according to refractive index anisotropy and the first thickness of the liquid crystal layer, and a driving unit configured to output to the first pixel a first data voltage corresponding to the compensation gradation value of the first image signal.

1. A display apparatus, comprising:
a display panel comprising a liquid crystal layer, a first pixel having the liquid crystal layer with a first thickness and a second pixel having the liquid crystal layer with a second thickness and having a color filter disposed at a top or bottom portion of the liquid crystal layer, the second thickness is less than the first thickness; a data generating unit configured to generate a first image signal corresponding to the first pixel and a second image signal corresponding to the second pixel in response to an input image signal; a data converting unit configured to convert a gradation value of the first image signal into a conversion gradation value of the first image signal according to refractive index anisotropy and the first thickness of the liquid crystal layer; a first frame memory configured to store the conversion gradation value of the first image signal for a period of a frame; a first data compensating unit configured to generate a compensation gradation value of the first image signal according to the conversion gradation value of the first image signal generated from the data converting unit and the conversion gradation value of the first image signal stored in the first frame memory; and a driving unit configured to output to the first pixel a first data voltage corresponding to the compensation gradation value of the first image signal.
