Abstract
An OLED display includes pixels, each including a first light emission region having a first area and a first perimeter and a second light emission region disposed neighboring the first light emission region and having a second area and a second perimeter. The first area, the first perimeter, the second area, and the second perimeter respectively satisfy an equation of A1*P2=A2*P1, where A1 is the first area, P1 is the first perimeter, A2 is the second area, and P2 is the second perimeter.
Claims7
An organic light emitting diode (OLED) display comprising a plurality of pixels, at least one pixel including:
- a first light emission region having a first area A1 and a first perimeter P1;
- and
- a second light emission region disposed neighboring the first light emission region and having a second area A2 and a second perimeter P2,
- wherein when an area of one of the first and second light emission regions is smaller than that of another of the first and second light emission regions, a perimeter of the one of the first and second light emission regions is smaller than that of the another of the first and second light emission regions, and wherein:
- the first and second light emission regions correspond to respective sub-pixels of the at least one pixel, and emit light having different colors, respectively,
- the second area A2 of the second light emission region is different from the first area A1 of the first light emission region, and
- the first area A1, the first perimeter P1, the second area A2, and the second perimeter P2 satisfy an equation A1*P2=A2*P1 such that an area ratio of the first area A1 to the second area A2 is constant.
