Pixel arrangement and reflector structure of LED display and method of forming same

A light emitting diode (LED) display panel, comprising:

• a back plate;
• a pixel structure comprising a plurality of pixels, wherein each of the pixels comprises:
• a reflector structure disposed on the back plate, the reflector structure having a first reflective bank structure and a second reflective bank structure, the first reflective bank structure having a first bank opening, and the second reflective bank structure having a second bank opening, wherein the first bank opening has a first shape, the second bank opening has a second shape, and the second shape is a mirror shape of the first shape or a 180° symmetrical shape of the first shape;
• and
• a first LED and a second LED disposed on the back plate and emitting light of a same color, wherein the first LED is disposed within the first bank opening of the first reflective bank structure, and the second LED is disposed within the second bank opening of the second reflective bank structure;
• and
• an active driving layer having a plurality of driving units, wherein each of the driving units is configured to drive a corresponding one of the pixels, and each of the driving units has a shape different from a combination of the first shape of the first bank opening and the second shape of the second bank opening of the corresponding one of the pixels;
• wherein for each of the pixels, the first shape of the first bank opening is a triangle, and at least two corners of the first shape have an included angle less than 90°.
