摘要： A display apparatus and a display control method are provided. The display apparatus includes an organic light-emitting display device having electrostatic attraction and including a transparent cathode layer and a transparent anode layer, so that the organic light-emitting display device can achieve bidirectional light emission; frustrated total reflection devices positioned on both sides of the organic light-emitting display device respectively and each including an active film layer and a frustrated switch, wherein the frustrated switch is turned on or off according to a received control signal to control whether the active film layer has electrostatic attraction; and a sealant bonded between the organic light-emitting display device and the frustrated total reflection devices to form a gap therebetween. When the active film layer has electrostatic attraction, the light emitted by the organic light-emitting display device is emitted from the active film layer.

摘要： A display assembly includes a display panel and at least one optical film group each disposed on a display surface. Each optical film group includes a quarter-wave plate, a reflective polarizer and an absorbing polarizer. The reflective polarizer includes a reflective portion capable of allowing light with a polarization direction parallel to a polarization axis of the reflective polarizer to pass through and reflecting light with a polarization direction perpendicular to the polarization axis. An orthographic projection of an effective light-emitting area of at least one sub-pixel is substantially within an orthographic projection of the reflective portion. The absorbing polarizer is capable of allowing light with a polarization direction parallel to a polarization axis of the absorbing polarizer to pass through and absorbing light with a polarization direction perpendicular to the polarization axis. The polarization axis of the reflective polarizer is parallel to the polarization axis of the absorbing polarizer.
