DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18515563 titled 'DISPLAY DEVICE
Simplified Explanation
The abstract describes a display device with high luminance, high contrast, and low power consumption. It includes a transistor, a light-emitting element, a coloring layer, a phosphor layer, a first electrode, and a second electrode. The light-emitting element is connected to the electrodes, with the first electrode connected to the transistor. The coloring layer is positioned over the light-emitting element, with the phosphor layer between the light-emitting element and the coloring layer. The light-emitting element includes a light-emitting diode chip, and the phosphor layer emits light of a complementary color to the emission color of the light-emitting element.
- The display device includes a high luminance light-emitting element connected to electrodes for efficient operation.
- A coloring layer and phosphor layer are strategically positioned to enhance contrast and color accuracy.
- The use of a light-emitting diode chip and complementary color emission from the phosphor layer improves overall display performance.
