  • Publication number: 20210351238
    Abstract: 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.

  • Patent number: 11092841
    Abstract: A color filter includes a substrate including pixel areas and a light-shielding area which is disposed between adjacent pixels areas; and a color conversion layer which color-converts incident light of an incident color and emits color-converted light toward the substrate, the color conversion layer including a first color conversion pattern in a first pixel area among the pixel areas and with which the incident light of the incident color is converted into light of a first color; and a second color conversion pattern in a second pixel area among the pixel areas and with which the incident light of the incident color is converted into light of a second color; and a partition wall in the light-shielding area and between the first color conversion pattern and the second color conversion pattern, the partition wall including a light-scattering material which scatters light incident thereto.

  • Patent number: 10989859
    Abstract: 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.

  • Patent number: 10725339
    Abstract: 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.

  • Patent number: 10529272
    Abstract: 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.
