Provided is a color filter having improved light efficiency and color reproducibility. The color filter includes: a substrate having a plurality of pixel areas and a light blocking area surrounding the plurality of pixel areas; a light blocking layer on the light blocking area; a first color conversion layer on a first pixel area among the plurality of pixel areas and configured to convert incident light into light of a first color; a first color filter layer between the substrate and the first color conversion layer and configured to selectively transmit the light of the first color emitted from the first color conversion layer; and a light reflection layer between the first color conversion layer and the first color filter layer and including a reflective material.

Color filter and display device comprising same

A display device may include a substrate including a plurality of first areas and a plurality of second areas adjacent to the first areas, a pixel defining layer, and a light blocking layer. The pixel defining layer is disposed on the substrate. The pixel defining layer defines a plurality of first openings positioned in each of the first areas and a plurality of second openings positioned in each of the second areas. The light blocking layer is disposed in each of the second areas on the substrate and surrounds the second openings in the plan view. An area of each of the second openings may be larger than an area of each of the first openings in the plan view.

Display device

A display apparatus includes a light guide member disposed below a display member. A light source configured to generate light is disposed adjacent to the light guide member. The light guide member includes a plurality of diffraction on the light guide member. The diffraction patterns are spaced apart from each other in the first direction. The plurality of diffraction patterns diffract incident light, which is incident at an incident angle, to change the incident light to diffraction light having a diffraction angle. The incident angle is defined as an angle between the incident light and a normal line that is perpendicular to a top surface or a bottom surface of the light guide member. The diffraction angle, which is defined as an angle between the diffraction light and the normal line, has a magnitude less than that of the incident angle.

Backlight unit and display apparatus including the same

A backlight unit may include a light source, a light guide plate neighboring the light source, a low refractive index layer disposed on the light guide plate, a blocking layer disposed on the low refractive index layer, and a wavelength conversion layer disposed on the blocking layer and including quantum dots. A refractive index of the low refractive index layer may be less than a refractive index of the light guide plate.

Backlight unit and related display device

A display device includes: a data driver for driving a plurality of data lines; a voltage generator for generating at least one driving voltage to be provided to the data driver; and a driving controller for providing a second image signal and a reference gamma selection signal to the data driver in response to a first image signal and a control signal received from the outside, wherein the driving controller outputs a voltage control signal for changing a voltage level of the at least one driving voltage, and the reference gamma selection signal, based on metadata included in the first image signal, and the data driver receives the reference gamma selection signal and the at least one driving voltage to provide, to the plurality of data lines, data voltage signals corresponding to the second image signal.

Display device capable of gray scale expansion

A display device includes a display panel, a light guide plate disposed under the display panel, a light source disposed adjacent to one side surface of the light guide plate that generates a first light, a first refractive layer disposed between the light source and the one side surface of the light guide plate that has a refractive index greater than a refractive index of the light guide plate, and a second refractive layer disposed between the display panel and the light guide plate that has a refractive index less than the refractive index of the light guide plate. The first refractive layer includes a convex portion that protrudes into the one side surface of the light guide plate.

Backlight unit and display device having the same

A display apparatus includes a visual information inputting part, a mode determining part, a driver and a display panel. The visual information inputting part receives an eyesight of a user and a viewing distance of the user. The mode determining part determines a pixel perception distance based on the eyesight of the user and compares the viewing distance and the pixel perception distance to select one of a normal mode and a control mode. The driver maintains a vertical resolution of an input image and a frame frequency when the normal mode is selected, and outputs gate signals to gate lines during a same horizontal period to decrease the vertical resolution and inserts a compensation frame between adjacent frames to increase the frame frequency when the control mode is selected. The display panel displays an image based on the vertical resolution and the frame frequency set by the driver.

Display apparatus and method of driving the same

An optical device includes a display panel displaying an image and an optical modulation device that includes a first plate and second plate disposed to face each other and a liquid crystal layer disposed between the first plate and the second plate and including a plurality of liquid crystal molecules, wherein the first plate includes a plurality of lower electrodes extending in a first direction and arranged in a second direction crossing the first direction and the second plate include and an upper electrode. When the display panel displays a first image during a first subframe, the optical modulation device applies a first driving signal to the plurality of lower electrodes, and when the display panel displays a second image during a second subframe following the first subframe, the optical modulation device applies a second driving signal different from the first driving signal to the plurality of lower electrodes.
