Abstract: A display device includes a display panel, and the display panel includes a plurality of gate lines, a plurality of data lines, and a plurality of pixels connected to the plurality of data lines and the plurality of gate lines. A data driver provides data signals to the plurality of data lines. A gate driver sequentially generates gate signals corresponding to a start pulse using a clock signal, and provides the gate signals to the plurality of gate lines. A timing controller provides the clock signal and the start pulse to the gate driver. The gate driver compares a data signal provided to a first data line among the plurality of data lines and at least one of the gate signals to generate a feedback signal. The timing controller sets a delay value of the clock signal based on the feedback signal.

Abstract: A display device includes: a first pixel connected to a first scan line and a data line; a second pixel connected to a second scan line and the data line; and a data driver connected to the data line. The data driver includes: a data voltage generator which applies a data voltage corresponding to a grayscale value of the first pixel to the data line when a scan signal of a turn-on level is applied to the first scan line; and an off voltage generator which applies an off voltage corresponding to a black grayscale value to the data line when a scan signal of a turn-on level is applied to the second scan line, in a first mode.

Abstract: A color conversion substrate for displaying a first color, a second color, and a third color may include a base substrate, a first light-blocker, a second light-blocker, a pattern layer, a first color converter, and a second color converter. The first light-blocker contacts a surface of the base substrate and may block first light of the third color. The second light-blocker contacts the surface of the base substrate and may block second light of the third color. The pattern layer is disposed on the first light-blocker and the second light-blocker and includes an optical pattern that includes protrusions. The first color converter overlaps the first light-blocker and may convert a first portion of incident light into light of the first color. The second color converter overlaps the second light-blocker and may convert a second portion of the incident light into light of the second color.
