Abstract

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.

Description

technical field [0001] The invention relates to the technical field of keyboard lighting, in particular to a backlight keyboard. Background technique [0002] When choosing an electronic product, most users not only pay attention to its function, but also pay attention to its fashion and interest, especially in the pursuit of color. Therefore, the monochrome backlight keyboard can no longer meet the needs of consumers, and the keyboards with color backlight and multiple backlight modes are gradually favored by consumers. [0003] The backlight of the keyboard is usually realized by using a light-emitting diode LED matrix. When the voltage applied between the two poles of the LED exceeds the conduction voltage V f At the same time, LED electroluminescence, and the color of LED light is often different due to different LED materials. The color backlight keyboard needs to set LEDs of various luminous colors in the LED matrix of the keyboard at the same time. On the basis of t...
