It leads in area 6；Second anti-dazzling screen 3 is located at the lower part of light guide sheet 2, and is covered on the conducting region 6 and viewing area 4 of light guide sheet 2.
The second shading is arranged by the way that the first anti-dazzling screen 1 is arranged on the top of light guide sheet 2, in the lower part of light guide sheet 2 in the present invention
Piece 3 effectively prevents light leakage in 2 conductive process of light guide sheet, improves the guide-lighting distance of light guide sheet 2, increases the biography of light guide sheet 2
Efficiency is led, is reduced because light leakage is interference caused by cell phone components.
Specifically, referring to figs. 1 and 2, the shape of light guide sheet 2 is designed to irregular bar shaped.Perpendicular to from illumination
The direction of area 5 to viewing area 4 is cross-sectional direction, and light guide sheet 2 is less than or equal to the cross of viewing area 4 in the cross section of conducting region 6
Section, when light guide sheet 2 the cross section of area of illumination 5 be greater than viewing area 4 cross section when, the light-dispersing effect of viewing area 4 more evenly,
Good user experience can be provided；When light guide sheet 2 the cross section of area of illumination 5 be less than viewing area 4 cross section when, Ke Yiti
The effect of high 4 illumination of viewing area.
Referring to figs. 1 and 2, the first anti-dazzling screen 1 positioned at 2 top of light guide sheet is designed to be able to cover light guide sheet simultaneously
2 area of illumination 5 and the size and shape of conducting region 6, so that the not upward light leakage of light guide sheet 2.First anti-dazzling screen 1 can be designed to phase
Be same as or slightly larger than light guide sheet 2 size and shape, and in 4 aperture of viewing area to show illumination；Or be designed to be identical to or
The size and shape overall slightly larger than area of illumination 5 and conducting region 6, enables the first anti-dazzling screen 1 to cover area of illumination 5 and conducting region
6 light leakage.
In conjunction with shown in Fig. 1 and Fig. 3, the second anti-dazzling screen 3 positioned at 2 lower part of light guide sheet is designed to the conduction of covering light guide sheet 2
