Problems solved by technology

There are generally two reasons for this phenomenon: one is that the light transmission area of ​​the key itself is relatively large, and more light is transmitted, such as the window key and print key in the ordinary keyboard; the other is the structural reason, the backlight module The light source (such as light-emitting diodes) may be just below some keys, and the light is directly emitted from the light-transmitting part of the keycap. When the eyes are in this range, the user will feel dazzling

Abstract

The invention provides a luminescent keyboard which comprises a key-press module and a backlight module; the key-press module comprises a support plate and at least one keycap; the support plate is provided with a through-hole; the keycap is arranged on the support plate and can move up and down relative to the support plate; the backlight module is arranged below the support plate; the backlightmodule comprises a light guide plate, a light source and an anti-dazzling screen; the power source is arranged on the light guide plate; the anti-dazzling screen is arranged between the light guide plate and the support plate and provided with a first light transmission part and a second light transmission part corresponding to the keycap; and the transmittance of the first light transmission part is smaller than the transmittance of the second light transmission part, wherein, the light source provides rays of light to the keycap from the anti-dazzling screen and the through-hole via the light guide plate. The luminescent keyboard has the advantages that the brightness of the luminescent keyboard can be locally regulated.

Description

technical field [0001] The present invention relates to a luminous keyboard, in particular to a luminous keyboard with adjustable local brightness. Background technique [0002] Illuminated keyboard is a keyboard that can emit light by itself. Generally speaking, after spraying paint on the transparent keycaps, laser engraving is used to form characters, and the light of the backlight module shines from under the keycaps and shines through the transparent characters to form a luminous effect. [0003] For luminous keyboards, users hope that the light emitted by them is uniform and soft, but sometimes some keys are too bright or even dazzling. There are generally two reasons for this phenomenon: one is that the light transmission area of ​​the key itself is relatively large, and more light is transmitted, such as the window key and print key in the ordinary keyboard; the other is the structural reason, the backlight module The light source (such as light-emitting diode) in ...
