Abstract: An organic light-emitting diode display device can include a substrate including first, second and third sub-pixels, each of the first, second and third sub-pixels including an emission area and a non-emission area; a driving thin film transistor in the non-emission area of each of the first, second and third sub-pixels; a light-emitting diode connected to the driving thin film transistor; a polarizer at an outer surface of the substrate, the polarizer including a reflective polarizer; and a light control pattern disposed inside of the substrate and corresponding to the non-emission area, the light control pattern being configured to change a direction of light incident on the light control pattern.

Abstract: A display device includes a micro-lens film which has a high fill-factor and a high luminance ratio and prevents generation of moiré. The display device includes a display panel configured to display an image, a plurality of Light Emitting Diodes (LEDs) configured to generate light to supply light to the display panel, a light guide panel configured to guide light to the display panel, and a micro-lens film including a base film that concentrates and diffuses light emitted from the light guide panel, a lens unit at an upper surface of the base film, and a back-coating film at a lower surface of the base film. The lens unit includes unit block groups randomly arranged at the upper surface of the base film, each unit block group containing randomly arranged fixed-shape lenses having different sizes, and micro-beads randomly formed on surfaces of the fixed-shape lenses.
Abstract translation: 显示装置包括具有高填充因子和高亮度比并防止产生莫尔条纹的微透镜膜。 该显示装置包括被配置为显示图像的显示面板，配置成产生向显示面板供给光的光的多个发光二极管（LED），配置为将光引导到显示面板的导光面板，以及微型显示面板 所述薄膜包括浓缩并扩散从所述导光板发出的光的基膜，所述基膜的上表面处的透镜单元和所述基膜的下表面处的背涂膜。 透镜单元包括随机地设置在基膜的上表面的单位块组，每个单位块组包含随机排列的具有不同尺寸的固定形状的透镜，并且在固定形状的透镜的表面上随机形成微珠。
