Abstract: The present invention provides a color conversion layer, a manufacturing method of the color conversion layer, and a display panel. The color conversion layer is used in a display panel having a direct surface light source. The color conversion layer includes a quantum dot film and a functional film. The functional film is arranged at one side of the quantum dot film facing the direct surface light source. A light wave emitted by the direct surface light source is transmitted through the functional film into the quantum dot film. A light wave excited by the quantum dot film is reflected into the quantum dot film through the functional film.

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 L 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.
