Data driving circuit, controller, display device and method for driving the same

Abstract

Various embodiments provide a data driver circuit, a controller, a display device, and a method of driving the same. Overlap driving of overlapping subpixels and fake data insertion driving of inserting a fake image, different from real images, into each of a plurality of lines are performed in a combined manner. Image quality is improved, despite of combined driving.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2018-0091241 filed on Aug. 6, 2018, which is incorporated herein by reference for all purposes as if fully set forth herein. technical field [0003] Exemplary embodiments relate to a data driving circuit, a controller, a display device and a driving method thereof. Background technique [0004] In response to the development of the information society, various types of display devices for displaying images are increasingly required. In this regard, a series of display devices such as liquid crystal display (LCD) devices, plasma display devices, and organic light emitting diode (OLED) display devices have recently been widely used. [0005] Such a display device is capable of performing display driving by charging capacitors respectively provided in each of a plurality of sub-pixels arranged in a display panel. However, in prior art display device...

Problems solved by technology

However, in prior art display devices, some sub-pixels may not be fully charged, thereby degrading the image quality, which becomes a problem

Also, in the prior art, the image may be blurred rather than clearly discernible, or there may be brightness differences due to different lighting periods depending on the line position, reducing image quality
