摘要： A pixel structure includes a plurality of subpixels. The subpixels include red subpixels, green subpixels, and blue subpixels. The red subpixels and the green subpixels are all substantially in an isosceles triangular shape and have substantially a same area. Each blue subpixel is in substantially a rhombic shape and has an area substantially twice the area of the red subpixel or green subpixel. Each leg of the isosceles triangular shape of the red or green subpixel has a length equal to a side length of the rhombic shape of the blue subpixel. The display panel using the subpixel rendering algorithm has visual resolution greater than physical resolution. The enlarged blue subpixel extends life span to make all three color subpixel have similar life span.
