US 2014/0210872 A1 · DISPLAY CONTROL CIRCUIT, LIQUID CRYSTAL DISPLAY APPARATUS HAVING THE SAME, AND DISPLAY CONTROL METHOD

Abstract

An object of the present invention is to reduce noise during three-dimensional display without increasing memory capacity in a liquid crystal display apparatus capable of displaying an image in two display modes of a 2D mode (two-dimensional display) and a 3D mode (three-dimensional display). In an SDRAM as a volatile memory provided in a timing controller IC, data necessary for a correcting process to an input image signal is stored as follows. Overdrive data is compressed at a relatively high compression degree in the 2D mode and is compressed at a relatively low compression degree in the 3D mode, and the compressed data is stored into the SDRAM. Display unevenness correction data is compressed at a relatively low compression degree in the 2D mode and is compressed at a relatively high compression degree in the 3D mode, and the compressed data is stored into the SDRAM.

Dependent claims

A display control circuit for generating write gray scale data to be supplied to a display panel capable of displaying an image in two display modes of two-dimensional display and three-dimensional display, based on an image signal sent from an outside, the display control circuit comprising:

a display unevenness correcting unit performing a correction to the image signal for suppressing occurrence of display unevenness at the time of displaying an image on the display panel;
an overdrive unit performing a correction for emphasizing a temporal change of a signal to the image signal corrected by the display unevenness correcting unit, and generating the write gray scale data;
and
a volatile memory for storing display unevenness correction data as data used for a process by the display unevenness correcting unit and overdrive data as data used for a process by the overdrive unit, wherein
when a capacity for storing the display unevenness correction data out of a capacity of the volatile memory is defined as a first capacity, and a capacity for storing the overdrive data out of the capacity of the volatile memory is defined as a second capacity,
the first capacity during the two-dimensional display is larger than that during the three-dimensional display, and
the second capacity during the three-dimensional display is larger than that during the two-dimensional display.
