DISPLAY APPARATUS

摘要

A controller for a display panel includes a detector, a timing controller, and a voltage generator. The detector detects a predetermined pattern in an image signal. The timing controller generates a control signal based on detection of the pattern. The voltage generator changes at least one driving voltage for a display panel from a first level to a second level based on the control signal. The predetermined pattern may correspond to at least one region having a predetermined arrangement of at least first and second gray scale values of pixels in an image corresponding to the image signal.

1. A display apparatus, comprising:
a display panel including a plurality of pixels connected with a plurality of gate lines and a plurality of data lines; a gate driver configured to drive the plurality of gate lines; a data driver configured to drive the plurality of data lines; a timing controller configured to provide the data driver with a plurality of clock signals and a data signal, to control the gate driver, and to output a voltage control signal and a gray scale compensation signal when an image signal provided from an external device has a predetermined image pattern; and a voltage generator configured to generate a plurality of operating voltages in response to the voltage control signal, wherein the data driver is to convert the data signal into a gray scale voltage based on reference gray scale voltages corresponding to the gray scale compensation signal and to drive the data lines with the gray scale voltage.
