A pixel arrangement for a display is provided. The pixel arrangement comprises a plurality of sub-pixels. At least one sub-pixel comprises a perovskite light emitting diode. In one embodiment, a first sub-pixel is configured to emit a first colour of light, and includes a perovskite light emitting diode. A second sub-pixel is configured to emit a second colour of light that is different from the first colour, and a third sub-pixel is configured to emit a third colour of light that is different from the first and second colour. The second sub-pixel comprises a perovskite light emitting diode, an organic light emitting diode or a quantum dot light emitting diode. The third sub-pixel comprises a perovskite light emitting diode, an organic light emitting diode or a quantum dot light emitting diode.
A pixel arrangement for a display, the arrangement comprising a plurality of pixels, each pixel comprising:
The pixel arrangement of any one of the preceding claims, wherein one of the first, second and third sub-pixels emits red light;
The pixel arrangement of any one of the preceding claims, wherein each of the first, second and third sub-pixels have the same surface area.
The pixel arrangement of any one of the preceding claims, wherein the pixel arrangement further comprises a fourth sub-pixel configured to emit a fourth colour of light that is different from the first, second and third colour of light, the fourth sub-pixel comprising a PeLED, an OLED or a QLED.
The pixel arrangement of any one of the preceding claims, wherein one or more of the PeLEDs comprise organic metal halide light-emitting perovskite material.
The pixel arrangement of any one of the preceding claims, wherein one or more of the PeLEDs comprise inorganic metal halide light-emitting perovskite material.
A display comprising the pixel arrangement of any one of the preceding claims.
