Embodiment Construction

[0043] In a specific embodiment of the present invention, a light-emitting module is arranged under the key, and the light-emitting module is driven by a power supply module. The light-emitting module emits light to illuminate the keycap from the inside, so that the logo on the keycap can be seen by the user.

[0044] The keyboard in the embodiment of the present invention includes a casing, keys and a keyboard circuit board, and each key includes a keycap provided with a preset logo, wherein the keyboard also includes a light emitting device, such as figure 1 As shown, the light emitting device includes:

[0045] At least one light-emitting module is arranged under the keycap;

[0046] A power supply module, connected to the at least one light-emitting module, controls the work of the at least one light-emitting module;

[0047] The light emitted by the light emitting module can pass through the keycap, so that the preset logo on the keycap can be recognized by the user.

Abstract

The invention provides a keyboard and a notebook computer. The keyboard comprises a shell, keys and a keyboard circuit board, wherein each key comprises a key cap with a preset mark. The keyboard is characterized by also comprising a light emitting device, wherein the light emitting device comprises at least one light emitting module and a power supply module; the light emitting module is arranged below the key cap; the power supply module is connected with the at least one light emitting module to control the operation of the at least one light emitting module; and light emitted by the light emitting module can penetrate through the key cap, so the preset mark on the key cap can be recognized by a user. In the invention, marks on the keys of the keyboard can be clearly recognized by the user even in a dark environment, so the convenience in input of the user is improved.

Description

technical field [0001] The invention relates to keyboard technology, in particular to a keyboard and a notebook computer. Background technique [0002] As an indispensable input device for ordinary computers, the keyboard is used to perform input functions. [0003] However, the existing keyboards have the following problems during use. For example, in a dark environment, the user cannot clearly see the settings of the keys on the keyboard, resulting in increased misoperations, especially for some unskilled users, such as the elderly and children. Wait. [0004] In order to solve the above-mentioned misoperation problem in a dark environment, it can be solved by setting a special external keyboard light. However, the above-mentioned scheme of using the keyboard light to illuminate the keyboard has at least the following disadvantages: [0005] When performing an input operation, the user's palm always covers a part of the keyboard, and the keyboard light cannot illuminate ...
