Document Type and Number:
WIPO Patent Application WO/2018/188360
Kind Code:
A1
Abstract:
An LED chip, an LED light emitting substrate, a display device and a control method therefor. The LED chip comprises an N-type semiconductor layer (10), a P-type semiconductor layer (30), and a quantum well layer (20) located between the N-type semiconductor layer (10) and the P-type semiconductor layer (30). The quantum well layer (20) is made of indium gallium nitride, wherein the molar ratio of indium atoms in indium gallium nitride is greater than or equal to 0.3.
