Problems solved by technology

When the predetermined grayscale range is the high grayscale range, compensation accuracy in the low grayscale range may decrease
Also, for optical compensation, it may take a lot of time (such as tens of seconds or longer) to capture an image in a low grayscale range using a camera, and the compensation accuracy in the low grayscale range may decrease

Embodiment Construction

[0042] Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings.

[0043] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The same reference numerals refer to the same elements throughout.

[0044] It will be understood that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

Abstract

The invention discloses a display apparatus and a method of compensating an image of a display panel using the same. The display apparatus includes a first compensator, a second compensator and a display panel including pixels. The first compensator generates a first compensation coefficient based on sensing data of a pixel of the pixels for a first grayscale value, generates a second compensation coefficient based on camera imaging data for a second grayscale value greater than the first grayscale value and compensates image data based on the first compensation coefficient and the second compensation coefficient. The second compensator compensates the image data by modeling sensing data of entire grayscale range based on sensing data of the pixel for a third grayscale value and a fourth grayscale value. The display panel displays an image based on the image data compensated by the first compensator and the second compensator.

Description

technical field [0001] Embodiments of the present invention relate to a display device and a method of compensating an image of a display panel using the display device. More particularly, embodiments of the present invention relate to a display device improving compensation accuracy of a low gray scale range and a method of compensating an image of a display panel using the display device. Background technique [0002] Generally, a display device includes a display panel and a display panel driver. The display panel includes a plurality of gate lines, a plurality of data lines and a plurality of pixels. The display panel driver includes a gate driver and a data driver. The gate driver outputs gate signals to the gate lines, respectively, and the data driver outputs data voltages to the data lines, respectively. [0003] The display device may operate optical compensation including capturing an image of the display panel using a camera and compensating for smudges of the ...
