  • Publication number: 20230189436
    Abstract: A display unit includes a display panel, a circuit board bent from a front surface of the display panel toward a rear surface of the display panel, a window disposed on the front surface of the display panel to cover an active area, and a cover panel film disposed on the rear surface of the display panel and disposed between the display panel and the circuit board. The cover panel film includes a first portion overlapping with the display panel, and a second portion extending from the first portion to protrude from the display panel when viewed in a plan view. The second portion is disposed between the circuit board and the window when viewed in a cross-sectional view.

  • Patent number: 11189671
    Abstract: A display device may include at least one optical control unit including first refractive index layers, second refractive index layers, and an optical compensation layer. The second refractive index layers may be stacked in an alternating manner with the first refractive index layers and may have a refractive index different from that of the first refractive index layers. The optical compensation layer may be disposed at least on the uppermost refractive index layer of the first and second refractive index layers to be in contact with the uppermost refractive index layer or below the lowermost refractive index layer of the first and second refractive index layers to be in contact with the lowermost refractive index layer. The optical compensation layer may have a thickness less than those of the first and second refractive index layers.

  • Patent number: 9666124
    Abstract: A pixel includes a pixel circuit to control an amount of current supplied from a first power source to an organic light emitting diode (OLED) based on a data signal. At least one first transistor is located in a current path between the first power source and OLED. A second transistor is coupled between a gate electrode of the at least one first transistor and an emission control line through which an emission control signal is supplied. The emission control line controls a state of the at least one first transistor, and the second transistor turns on or off based on the data signal.
