The present disclosure is related to a touchpad structure, which includes a cover plate, a backlight unit, a touch circuit layer, a first optical modulation layer, and a second optical modulation layer. The first optical modulation layer is disposed between the cover plate and the backlight unit, and having a first reflectivity. The second optical modulation layer is disposed between the first optical modulation layer and the touch circuit layer. The second optical modulation layer has a second reflectivity and a first penetration rate, wherein the second reflectivity is the same as the first reflectivity, or the first reflectivity is the same as the first penetration rate. The touchpad structure can present a uniform color spectrum via the second optical modulation layer and the first optical modulation layer.

Touchpad structure

A circuit structure includes a light-transmissive insulation layer, a patterned conductive layer and an electronic component. The patterned conductive layer is disposed on the light-transmissive insulation layer. The electronic component is disposed on the patterned conductive layer and electrically connected to the patterned conductive layer.

Circuit structure, backlight module and light-emitting key device using the same

An input device including a bracket, key caps and a black light module is provided. The key caps are disposed on the bracket. The backlight module is disposed under the bracket, and includes a light guide plate, a light source and a shading plate. The light guide plate includes diffusing elements arranged at a position corresponding to an opening of the bracket. The light source is disposed on a side of the light guide plate. The shading plate is disposed on the light guide plate, and includes a transparent sheet, an opaque layer and a translucent coating. The opaque layer is disposed on the transparent sheet correspondingly between two adjacent key caps, and the translucent coating overlaps a portion of the opaque layer on the transparent sheet.

Backlight module and input device

Systems and methods for intelligent fan identification are described. In some embodiments, an Information Handling System (IHS) may include: an embedded controller (EC); and a memory coupled to the EC, the memory having program instructions stored thereon that, upon execution by the EC, cause the IHS to: detect a cooling fan configuration issue; determine that a number of cooling fans in the IHS has not changed between a previous configuration and a current configuration; and in response to the determination, abstain from identifying the cooling fan configuration issue as a cooling fan error.

System and methods for intelligent fan identification including fan quantity change detecting during POST

The disclosure provides a backlight module and an input device, wherein the backlight module is adapted to be arranged under a bracket of the input device. The backlight module includes a reflector, a light guide plate, a light source, and a shading plate. The light guide plate is disposed on the reflector and includes a plurality of diffusing elements. The light source is located on a light incident side of the light guide plate. The shading plate is disposed on the light guide plate. The shading plate has a shading area and a translucent area. The diffusing elements are arranged corresponding to the translucent area, wherein a transmittance of the translucent area is greater than a transmittance of the shading area. The scattering or diffusing particles are arranged in the translucent area.
