    摘要： A display panel is disclosed. The display panel may include a plurality of LED elements, and may further include a substrate including a first driving circuit including a pulse width modulation (PWM) driving circuit and a second driving circuit including a pulse amplitude modulation (PAM) driving circuit. The plurality of LED elements may include a first LED element configured to emit light of a first color, and which is controlled by the first driving circuit, and a second LED element configured to emit light of a second color different from the first color, and which is controlled by the second driving circuit.
