Embodiment Construction

[0053] As the number of wires and the difficulty of integration increase, the possibility of parasitic coupling between (coupling) wires or between wires and elements also increases, which causes fluctuations in the brightness of the OLED.

[0054] Hereinafter, the described technology will be explained in detail with reference to the accompanying drawings. In this disclosure, under some applications and according to those skilled in the art, the term "substantially" includes the meaning of completely, nearly completely, or to any significant degree. In addition, "formed on" may also mean "formed on". The term "connected" may include electrically connected.

[0055] figure 1 is a block diagram illustrating a coupling compensator of a display panel according to example embodiments. figure 2 is shown included in the figure 1 A diagram of an example of a first data converter in a coupled compensator for a display panel. Depending on the embodiment, certain elements can be s...

Abstract

A coupling compensator for a display panel and a display device including the coupling compensator are disclosed. In one aspect, the coupling compensator includes a memory configured to receive grayscale data and store the grayscale data and a first data converter configured to convert the grayscale data to a plurality of grayscale data voltages including first and second grayscale data voltages. The compensator also includes a coupling voltage calculator configured to calculate a line coupling voltage generated on a data line based on the difference between the first grayscale data voltage corresponding to the grayscale data provided to a first group of the pixels in an (N?1)th row and the second grayscale data voltage corresponding to the grayscale data provided to a first group of the pixels in an Nth row, where the N is an integer equal to or greater than 2.

Description

technical field [0001] The technology described generally relates to a coupling compensator for a display panel and a display device including the coupling compensator. Background technique [0002] Flat panel displays (FPDs) are widely used because they are relatively lightweight and thin compared to cathode ray tube (CRT) displays. Examples of flat panel technologies include liquid crystal displays (LCDs), field emission displays (FEDs), plasma display panels (PDPs), and organic light emitting diode (OLED) displays. OLED technology has been considered as a next-generation display because of its favorable characteristics such as wide viewing angle, fast response speed, thin profile, low power consumption, and the like. [0003] Generally, an OLED display includes a plurality of scan lines, a plurality of data lines, a plurality of pixel circuits connected to the scan lines and the data lines, and a matrix of OLEDs included in the pixel circuits. As the resolution of the O...
