DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17720403 titled 'DISPLAY APPARATUS

Simplified Explanation

The patent application describes a display apparatus that includes a circuit substrate and a pixel array with LED cells. The LED cells have semiconductor layers and an active layer in between. The apparatus also includes wavelength converters, reflective electrodes, a common electrode, and pad electrodes.

• The display apparatus includes driving circuits and bonding electrodes on a circuit substrate.
• The pixel array consists of LED cells with semiconductor layers and an active layer.
• Second bonding electrodes are placed on the first bonding electrodes.
• Wavelength converters are present on the LED cells.
• An upper semiconductor layer with a partition structure surrounds the wavelength converters and separates them.
• A first reflective electrode is placed on the side surfaces of the LED cells, separated by a passivation layer.
• Second reflective electrodes are on the lower surfaces of the LED cells and connected to the semiconductor layers.
• A common electrode is present on at least one side of the LED cells.
• A pad electrode is located outside the LED cells and connected to the driving circuits.
