DISPLAY DEVICE INCLUDING A LIGHT CONTROL LAYER AND MANUFACTURING METHOD OF THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17887007 titled 'DISPLAY DEVICE INCLUDING A LIGHT CONTROL LAYER AND MANUFACTURING METHOD OF THE SAME
Simplified Explanation
The patent application describes a display device that includes a display panel and a light control layer. The display panel has a pixel defining film and a light-emitting element, and the light control layer includes a pattern layer and a cover layer.
- The display panel has a pixel opening through which the first electrode of the light-emitting element is exposed.
- The light control layer overlaps the pixel opening and consists of a pattern layer and a cover layer.
- The pattern layer has an upper surface, a lower surface, and a side surface, with the angle between the side surface and the lower surface being an acute angle.
- The cover layer covers the pattern layer and has a lower refractive index than the pattern layer.
Potential applications of this technology:
- This display device can be used in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
- It can enhance the visual quality and brightness of the display by controlling the light emitted from the light-emitting element.
Problems solved by this technology:
- The light control layer helps to improve the contrast ratio and reduce unwanted light reflections, resulting in better image quality.
- The exposed first electrode through the pixel opening allows for efficient light emission and improved overall display performance.
Benefits of this technology:
- The display device provides improved visual quality with enhanced contrast and reduced reflections.
- It allows for efficient light emission, resulting in brighter and more vibrant displays.
- The use of the light control layer helps to optimize the viewing experience by minimizing unwanted light interference.
Original Abstract Submitted
A display device includes: a display panel including a pixel defining film and a light-emitting element, wherein the pixel defining film includes a pixel opening, wherein the light-emitting element includes a first electrode, a light-emitting layer, and a second electrode, and wherein the first electrode is at least partially exposed through the pixel opening; and a light control layer including a pattern layer and a cover layer, wherein the pattern layer overlaps the pixel opening, and wherein the cover layer covers the pattern layer and has a refractive index lower than that of the pattern layer, wherein: the pattern layer includes an upper surface, a lower surface opposite to the upper surface, and a side surface connecting the upper surface and the lower surface to each other, and an angle between the side surface and the lower surface is an acute angle.
