The embodiment of the invention discloses a backlight keyboard, which relates to the technical field of keyboard lighting, and is used to solve the problem that the design of the LED matrix in the existing backlight keyboard does not consider the conduction voltage difference of the LEDs, which affects the display effect of some backlight modes. The backlit keyboard includes: a key matrix, a light-emitting diode LED matrix, and a keyboard controller. The LEDs in the LED matrix are set to backlight the keys in the key matrix, and the keyboard controller is used to detect the pressing operation of the keys in the key matrix. The interface group of multiple light control interfaces controls the light emission of the LEDs in the LED matrix; the LED matrix includes a first LED and a second LED, the first conduction voltage of the first LED is higher than the second conduction voltage of the second LED, and the second conduction voltage of the second LED is higher than the second conduction voltage of the second LED. The first electrode of the LED is connected to the first light control interface of the interface group through the target diode group.
