摘要:
The present disclosure provides an OLED pixel unit, a method for producing the same, a display panel and a display apparatus. The OLED pixel unit includes an organic light emitting diode configured to emit a light within a wavelength range; and a photonic crystal array located at a light exit side of the organic light emitting diode, structural parameters of the photonic crystal array depending on a preset color of the OLED pixel unit. The light emitted from the OLED has a wavelength which is selected by the photonic crystal array such that the preset color is presented at the light exit side of the OLED. It can achieve high resolution over the conventional means due to the photonic crystal array having a machining size in nanometers. Thus, the resolution of the OLED pixel unit using the photonic crystal array can be improved significantly.

A novel display panel that can be used as a reflective display panel in an environment with strong external light and as a self-luminous display panel in a dim environment, for example and that has low power consumption and is highly convenient or reliable is provided. The display panel includes a pixel and a substrate that supports the pixel. The pixel includes a first display element (e.g., a reflective liquid crystal element) that includes a reflective film having an opening as a first conductive film and a second display element (e.g., an organic EL element) that emits light to the opening.

A double-faced display panel and a double-faced display device including the double-faced display panel are provided. The double-faced display panel includes: a first display sub-unit, provided with a first display surface and a first non-display surface opposite to each other; a second display sub-unit, provided with a second display surface and a second non-display surface opposite to each other, and arranged back to back with the first display sub-unit, the second non-display surface facing the first non-display surface; and a reflection unit, arranged between the first display sub-unit and the second display sub-unit, wherein the reflection unit is configured to reflect display light emitted from the first display sub-unit back to the first display sub-unit and reflect display light emitted from the second display sub-unit back to the second display sub-unit. As the reflection unit is adopted, the displaying light emitted from the first display sub-unit and the second display sub-unit and travelling to the non-display surfaces can be reflected and reused, thus improving light utilization of the double-faced display device, improving brightness of the double-faced display device and enabling the double-faced display device to have a better contrast.
