DISPLAY DEVICE, DISPLAY PANEL AND MANUFACTURING METHOD THEREOF, DRIVING CIRCUIT AND DRIVING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 17630906 titled 'DISPLAY DEVICE, DISPLAY PANEL AND MANUFACTURING METHOD THEREOF, DRIVING CIRCUIT AND DRIVING METHOD

Simplified Explanation

The present disclosure is about a display device, a display panel, and a driving circuit, along with a driving method. The display panel consists of a driving backplane and a light emitting device layer. The driving backplane has multiple pixel driving circuits, while the light emitting device layer has multiple light emitting units arranged in an array. Each light emitting unit comprises multiple light emitting devices stacked away from the driving backplane. The light emitting devices, except for the one closest to the driving backplane, are transparent. Within the same light emitting unit, some of the light emitting devices are connected to the pixel driving circuits to emit light when driven by them. Additionally, at least two light emitting devices within the same light emitting unit have different light emitting materials.

  • The patent application describes a display panel with a unique structure that includes a driving backplane and a light emitting device layer.
  • The driving backplane consists of multiple pixel driving circuits, while the light emitting device layer contains multiple light emitting units arranged in an array.
  • Each light emitting unit is made up of multiple light emitting devices stacked away from the driving backplane.
  • The light emitting devices, except for the one closest to the driving backplane, are transparent.
  • Within the same light emitting unit, some of the light emitting devices are connected to the pixel driving circuits to emit light when driven by them.
  • Furthermore, at least two light emitting devices within the same light emitting unit have different light emitting materials.

Potential Applications

This technology has potential applications in various display devices, such as televisions, computer monitors, smartphones, and wearable devices. It can also be used in signage, advertising displays, and automotive displays.

Problems Solved

The disclosed technology addresses the need for improved display panels by providing a unique structure that enhances the performance and efficiency of light emitting devices. It solves the problem of limited color reproduction and pixel density in conventional display panels.

Benefits

The use of multiple light emitting devices with different light emitting materials within the same light emitting unit allows for improved color reproduction and a wider color gamut. The transparent light emitting devices also contribute to higher pixel density and improved overall display quality. Additionally, the driving backplane with multiple pixel driving circuits enables efficient control and driving of the light emitting devices, resulting in enhanced energy efficiency and reduced power consumption.
