DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17921405 titled 'DISPLAY APPARATUS
Simplified Explanation
The present disclosure describes a display apparatus that includes a complex refractive layer and a polarizer. The complex refractive layer is positioned on the side of the polarizer that faces away from the electroluminescent display panel. Its purpose is to convert linearly polarized light into circularly polarized light. This conversion occurs when the linearly polarized light, in different polarization states, passes through the glass and enters the complex refractive layer before reaching the polarizer. When the film-forming stretching direction of the complex refractive layer and the first direction form an acute angle, almost all of the circularly polarized light can pass through the polarizer, effectively eliminating the Mura phenomenon.
- A complex refractive layer is placed on the side of the polarizer facing away from the electroluminescent display panel.
- The complex refractive layer converts linearly polarized light into circularly polarized light.
- Linearly polarized light in different polarization states passes through the glass and enters the complex refractive layer before reaching the polarizer.
- When the film-forming stretching direction of the complex refractive layer and the first direction form an acute angle, most of the circularly polarized light can pass through the polarizer.
- This arrangement helps eliminate the Mura phenomenon, which refers to uneven brightness or color variations in a display.
Potential Applications
This technology can be applied in various display devices, such as televisions, computer monitors, smartphones, and tablets. It can improve the overall display quality by eliminating the Mura phenomenon and ensuring consistent brightness and color uniformity.
Problems Solved
The technology addresses the issue of the Mura phenomenon, which can cause uneven brightness or color variations in a display. By converting linearly polarized light into circularly polarized light and allowing it to pass through the polarizer, the Mura phenomenon is effectively eliminated, resulting in a more visually pleasing and uniform display.
Benefits
- Improved display quality with consistent brightness and color uniformity. - Elimination of the Mura phenomenon, leading to a more visually pleasing viewing experience. - Enhanced performance of display devices, such as televisions, monitors, smartphones, and tablets.
Original Abstract Submitted
The present disclosure provides a display apparatus. According to the present disclosure, a complex refractive layer is disposed on a side of the polarizer facing away from the electroluminescent display panel, and configured to convert the linearly polarized light into the circularly polarized light, so that the linearly polarized light in different polarization states having passed through the glass enters the complex refractive layer before entering the polarizer, the complex refractive layer converts the linearly polarized light into the circularly polarized light, and when the included angle between the film-forming stretching direction of the complex refractive layer and the first direction is an acute angle, almost all of the circularly polarized light can pass through the polarizer, thus eliminating the Mura phenomenon.
