Samsung Display Co., Ltd. patent applications published on November 9th, 2023

Summary of the patent applications from Samsung Display Co., Ltd. on November 9th, 2023

Samsung Display Co., Ltd. has recently filed several patents related to display devices and light-emitting diodes (LEDs). These patents aim to improve the efficiency and performance of LED-based display technologies.

In one patent application, Samsung describes an LED with improved light extraction efficiency and emission efficiency properties. The LED includes specific layers, such as a hole transport region consisting of three layers with different refractive indices. This configuration results in high light extraction efficiency and emission efficiency for the LED.

Another patent application focuses on an organic light-emitting device with specific components and compounds in its organic layer. The device includes a first electrode, a second electrode, and an organic layer containing an emission layer. The organic layer includes specific compounds represented by different formulas, which contribute to the device's light emission properties.

Samsung has also filed a patent application for an apparatus and method of manufacturing a display device. The apparatus includes a tilted mask assembly, a support unit, a deposition source, and a carrier. The mask assembly is tilted with respect to a ground plane, and the deposition source is positioned to face the mask assembly. The purpose of this invention is to provide an improved apparatus for manufacturing display devices.

Additionally, Samsung has filed a patent application for a display device with specific layers and components. The device includes a substrate, a lower metal layer, a light emitting element, a pixel defining layer, and a residual sacrificial layer. These components work together to create a functional display device.

Notable applications:

• LED with improved light extraction and emission efficiency.
• Organic light-emitting device with specific compounds in its organic layer.
• Apparatus and method for manufacturing a display device.
• Display device with specific layers and components.
