DISPLAY SUBSTRATE AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17634287 titled 'DISPLAY SUBSTRATE AND DISPLAY DEVICE

Simplified Explanation

The patent application describes a display substrate and device that use light emitting diode (LED) chips to emit light of different colors. Each LED chip consists of multiple light emitting units that emit light of the same color. Additionally, at least one light emitting unit includes a color conversion layer to convert the emitted light from one color to another.

• LED chips in the display substrate emit light of different colors.
• Each LED chip consists of multiple light emitting units that emit light of the same color.
• The light emitting units share a base and a first electrode.
• A color conversion layer is included in at least one light emitting unit to convert the emitted light from one color to another.

Potential Applications

• Display devices such as televisions, computer monitors, and mobile screens.
• Indoor and outdoor signage.
• Automotive lighting systems.
• Medical imaging displays.

Problems Solved

• Enables the production of displays with a wider range of colors.
• Provides flexibility in adjusting the color output of the display.
• Allows for more efficient use of LED chips by sharing components between light emitting units.

Benefits

• Improved color accuracy and vibrancy in displays.
• Greater customization and control over the color output.
• Enhanced energy efficiency by converting light to desired colors rather than filtering it out.

Original Abstract Submitted

A display substrate and a display device are provided. The display substrate includes light emitting diode chips, each light emitting diode chip includes light emitting units which respectively emit light of different colors, each light emitting unit includes a first electrode, a light emitting layer, a base and a second electrode, and the base and the second electrode are respectively located at both sides of the light emitting layer. In each light emitting diode chip, the light emitting units share the base and the first electrode, the light emitting layers of the light emitting units emit light of the same color, and at least one light emitting unit further includes a first color conversion layer located at a side of the base away from the light emitting layer, so as to convert first color light emitted by the light emitting layer into second color light.
