Abstract: An electronic device includes a display panel and a viewing angle control unit. The viewing angle control unit includes a first substrate; a second substrate; a first protrusion disposed between the first substrate and the second substrate; and a first shielding unit disposed between the first substrate and the second substrate and overlapped with the first protrusion, wherein the first shielding unit and the first protrusion respectively form a first projection and a second projection on the first substrate, the first and second projections respectively have a first maximum length (A) and a second maximum length (B) in a first direction satisfying the following formula (I), and the first and second projections respectively have a first maximum width (B) and a second maximum width (b) in a second direction satisfying the following formula (II): 2 ? A / a ? 1 ( I ) 2 ? B / b ? 1.

Abstract: An electronic device includes a display panel and a viewing angle control unit disposed opposite to the display panel. The viewing angle control unit includes a first substrate; a second substrate disposed opposite to the first substrate; and a plurality of protrusions disposed between the first substrate and the second substrate, wherein a transmittance of the plurality of protrusions is between about 0.006% and about 1.6%.

Abstract: A keyboard includes a transparent board, keyswitches, and a backlight module. The keyswitches could move upward and downward relative to the transparent board. At least one keyswitch includes a cap and a light exciting layer disposed in a transparent concave portion of the cap. The backlight module is disposed under the transparent board and includes a blue-light emitting diode, a reflection sheet, and a light guide plate having a light entrance surface, a light exit surface, and a bottom surface. The blue-light emitting diode is disposed corresponding to the light entrance surface for emitting light into the light guide plate. The reflection sheet is disposed on the bottom surface for reflecting light in the light guide plate to emit out of the light exit surface and then pass through the transparent board and the transparent concave portion, so that the light exciting layer could be excited to emit light.
