  • Publication number: 20240090280
    Abstract: A display device includes a display panel including a main area and a sensor area. Sensor devices overlap the sensor area of the display panel in a thickness direction of the display panel. The display panel includes first subpixels, which are disposed in the sensor area, and second subpixels, which are disposed in the main area. The number of transistors of each of the first subpixels is different from the number of transistors of each of the second subpixels.

  • Patent number: 10527883
    Abstract: The present invention relates to a reflective polarizer and a backlight unit including same and, more particularly, to a reflective polarizer and a backlight unit including same which can display excellent and uniform brightness throughout the visible light wavelength range in the following manner. Regardless of the incident angle of incident light, a discordance in the refractive index in one particular direction is minimized, and the transmissivity of polarized light targeted within the visible light wavelength range is uniform. Thus, light transmitted through the reflective polarizer is not biased toward a particular wavelength range, and the exterior is not colorful or a particular color due to rainbow-colored light. Because the reflectivity of polarized light not targeted within the visible light wavelength range is significantly large, the light is not biased toward a particular wavelength range.

  • Publication number: 20160320537
    Abstract: A reflection-type polarizer according to the present invention has an improved bright line visibility phenomenon and a wider viewing angle, compared with a conventional dispersion-type reflection polarizer, and can maximize luminance improvement while minimizing optical loss. In addition, in connection with implementing a reflection polarizer, a group dispersion body can be formed through simple control, making it possible to maximize productivity improvement through process simplification.

  • Patent number: 9170355
    Abstract: A reflective polarizer of the invention has excellent optical properties even though a very small number of polymer components per unit area is disposed inside a matrix thereof compared to reflective polarizers of the related art, which include birefringent polymer, since the polymer inside the matrix has a plate-like shape. This is advantageous for covering the entire range of visible light, since a plate-like polymer having a variety of optical thicknesses can be used. The additional processing of bonding the skin layer is not performed, since the skin layer is formed on at least one surface of the core layer in the state in which it is molten. This can greatly reduce manufacturing costs, and is advantageous in that it maximizes optical properties in a limited thickness.
