Abstract: Disclosed is a backlight test circuit including N circuit blocks. Each circuit block includes M mini-LED circuits, and each mini-LED circuit includes L mini-LEDs and a switching circuit. The L mini-LEDs are connected in parallel or in serial as a mini-LED set. The switching circuit controls the turning on and the turning off of the mini-LED set according to a control signal. N, M and M are positive integers. During a backlight test, in each circuit block, at least one of the mini-LED sets is turned on. By using this backlight test circuit, the abnormal mini-LED circuit can be found. Thus, a producer can only execute a rework process for the abnormal mini-LED circuit without extra cost.

Abstract: A three-dimensional (3D) display module and a 3D display device are disclosed. The 3D display module has a first assembly and second lens assemblies respectively having multiple first and second lenses arranged in parallel. The extending directions of the first and second lens assemblies intersect to form a specific angle and the refractive indexes of the first and second cylinder lenses are different. A liquid crystal layer is formed between the first and second cylinder lens assemblies. A first and second electrode layer are respectively formed on two sides of the liquid crystal layer. By a control technique of arranging the cylinder lens and the liquid crystals in a specific angle, a lateral and perpendicular autostereoscopic 3D display effect is accomplished. The 3D display module has advantages of a simple manufacturing and an advantage of thinning since a period and a focal length of the cylinder lens are smaller.
