According to information from the National Intellectual Property Administration, HGC Semiconductor Co., Ltd. and HGC (Wuhan) Technology Co., Ltd. have applied for a patent titled “A High Color Gamut Mini LED Light Emitting Element, Its Preparation Method, and Display Device,” with publication number CN119069607A, filed in October 2024.

Patent Overview
The patent summary shows that this application provides a high color gamut Mini LED light emitting element and its preparation method and display device. The high color gamut Mini LED light emitting element includes an LED chip and a color conversion film. The color conversion film is positioned on the light-emitting side of the LED chip. The color conversion film comprises a heat dissipation substrate and a color conversion layer located on the side of the heat dissipation substrate opposite the LED chip. The color conversion layer consists of multiple color conversion units arranged in an array, with narrow slits between any two adjacent units. These slits extend through the color conversion layer in the direction of the slit’s extension. The color conversion layer in the high color gamut Mini LED light emitting element enhances the color rendering ability of the Mini LED light emitting element, improving its color gamut. Additionally, the narrow slits that extend through the color conversion layer on the heat dissipation substrate can enhance the heat dissipation capability of the color conversion layer, further improving the reliability of the high color gamut Mini LED light emitting element.
