[embodiment]
See also Fig. 2 and Fig. 3, Fig. 2 is the schematic perspective view of first embodiment of the invention liquid crystal indicator, and Fig. 3 is the diagrammatic cross-section along II-II of Fig. 2 liquid crystal indicator.This liquid crystal indicator 100 comprises a display panels 10 and a plurality of light source 20.
This display panels 10 comprises a upper substrate 12, an infrabasal plate 14 and a liquid crystal layer (figure does not show) that is oppositely arranged, these a plurality of light sources 20 are four light emitting diode (LightEmitting Diode, LED), these four light emitting diodes are separately positioned on four sides of infrabasal plate 14, be respectively equipped with polaroid 31,32 on these two substrates that is oppositely arranged 12,14 outside surfaces, polaroid 32 outsides of infrabasal plate 14 also are provided with a reflector plate 30, and this polaroid 32 also can be selected reflective polaroid for use.
Wherein, four sides of this display panels 10 are equipped with reflectance coating (figure does not show).
See also Fig. 4, it is the lattice point structure that is provided with on the infrabasal plate 14.This lattice point structure is arranged on the surface with polaroid 32 of this infrabasal plate 14.
During work, enter display panels 10 by the light of the light source 20 outgoing side by infrabasal plate 14 and be transformed into uniform face light by the lattice point structure that is provided with on the infrabasal plate 14, light produces polarized light by polaroid 32 under the reflection of reflector plate 30, again by liquid crystal layer and at last from polaroid 31 outgoing.
Compared to prior art, because the liquid crystal indicator of present embodiment 100 is that light source is set directly at 14 4 sides of infrabasal plate, and doing the site on this infrabasal plate 14 handles, make the some light of incident or linear light change face light into and evenly penetrate, promptly omit some elements such as the light guide plate of backlight arrangement, thereby obtained a kind of liquid crystal indicator light and simple in structure.
