Zusammenfassung:The invention belongs to the technical field of projectors, and particularly discloses an energy-saving projector capable of controlling dynamic HDR of light source brightness in a partitioned mode, which comprises a shell, and a light-emitting unit, a first convex lens, an LCD screen, a second convex lens and a lens which are sequentially and linearly arranged and fixed in the shell, and the energy-saving projector is characterized in that the light-emitting unit is composed of a Mini LED chip or a Micro LED chip or an OLED chip. The Mini LED chip or the Micro LED chip or an OLED chip adoptedby the invention can control the light source in the partitioned manner, so that the contrast ratio of a display picture is increased, the energy consumption of the light source is reduced, the heatproductivity is reduced, and the service lives of the chip and the OLED are prolonged. 本发明属于投影仪技术领域,具体公开了一种可分区控制光源亮度动态HDR的节能型投影仪,包括外壳以及依次以直线排列固定在外壳内部的发光单元、第一凸透镜、LCD屏、第二凸透镜和镜头;其特征在于,所述发光单元由Mini LED芯片或者Micro LED芯片或者OLED芯片组成。本发明采
