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; a plurality of protrusions disposed between the first substrate and the second substrate; and a plurality of shielding units disposed between the first substrate and the second substrate and disposed corresponding to the plurality of protrusions. One of the shielding units forms a first projection on the first substrate, one of the protrusions forms a second projection on the first substrate, and the second projection falls within the first projection.

Abstract: A display device includes a viewing angle control panel and a backlight module. The backlight module is arranged below the viewing angle control panel, and includes a light source and an optical adjustment layer. The optical adjustment layer includes a first surface, a second surface and a plurality of openings. The second surface is arranged in opposite to the first surface and in proximity to the light source. The plurality of openings pass through the optical adjustment layer.

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.

Abstract: The invention relates to compounds of formula (I) ##STR1## wherein R.sup.1 is an optional substituent any position of phenyl ring and is selected from halogen, --NO.sub.2, --NH.sub.2, --OH and --O--CR.sub.1-6 alkyl;--CH.sub.2 R.sup.2 is a substituent at 1- or 3- position of 1,2,3,4-tetrahydroisoquinoline, whereinR.sup.2 is an azole group such as imidazole or triazole; andR.sup.3 is phenyl optionally substituted with one or more halogen,and pharmaceutical salts thereof.The compounds of formula (I) and salts thereof are useful as antifungal agents.The invention also relates to the antifungal pharmaceutical compositions containing the compounds of formula (I), the methods of treating fungal infections using the compounds of formula (I) and the process for preparing the compounds of formula (I).
