Abstract
A display screen allowing higher pixel density and thus better screen resolution by virtue of the structures connecting to LED chip light sources includes a substrate, a number of pad structures, the LED chips, and a number of carrier boards. Each pad structure includes a positive electrode pad and three negative electrode pads. Each LED chip package includes a red light chip, a green light chip, and a blue light chip arranged on the three negative electrode pads. Each carrier board includes a positive electrode connection terminal and a negative electrode connection terminal, the positive electrode connection terminal is electrically connected to the positive electrode pad, the negative electrode connection terminal is electrically connected to one red light chip, one green light chip, or one blue light chip. The disclosure also provides a displaying device having the display screen.
