DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18218664 titled 'DISPLAY APPARATUS
Simplified Explanation
The patent application describes a display apparatus that includes a circuit substrate with driver circuits and first bonding electrodes. The circuit substrate also has a pixel array with multiple pixels, each consisting of first to third sub-pixels. The pixel array also includes second bonding electrodes that are bonded to the first bonding electrodes.
The pixel array further includes a plurality of first LED cells corresponding to the first and third sub-pixels. Each first LED cell consists of a first conductivity-type semiconductor layer, a first active layer, and a second conductivity-type semiconductor layer. Additionally, the pixel array includes a plurality of second LED cells corresponding to the second sub-pixels. Each second LED cell consists of the first conductivity-type semiconductor layer, a second active layer, and the second conductivity-type semiconductor layer.
There is also a first electrode that extends to cover the upper surfaces of the first and second LED cells and is connected to the first conductivity-type semiconductor layers in common.
- The display apparatus includes a circuit substrate with driver circuits and bonding electrodes.
