Embodiment
In lcd technology, the light that backlight provides is generally white light.In order to realize colored display, need to arrange colored filter.Described colored filter comprises the filter unit of multiple transmission different colours light, realizes colored display by the combination of different colours.Such as: colored filter comprises red filter unit (transmission red light), green filter unit (transmit green light) and blue filter unit (transmitting blue light), colored display is realized by the combination of red, green, blue three primary colours.
The invention provides a kind of colored filter, comprise the filter unit of multiple transmission different colours light, each filter unit, while the light of TEM investigation color, reflects the light of other color except corresponding color.The light of described filter unit reflection is reflected back toward colored filter, again via the filter unit transmission of corresponding color.Such as: red filter unit is while transmit red light, and reflect green light and blue light, green glow and the blue light of the reflection of red filter unit are reflected back colored filter more again, and green glow is via the transmission of green filter unit, and blue light is via the transmission of blue filter unit.Because filter unit can reflect the light of other color except corresponding color, and the light of reflection can be reflected back colored filter more again, can recycle, thus effectively improve the utilization ratio of light, reduce energy consumption.
For liquid crystal indicator, the light inciding colored filter is provided by backlight, and the light of filter unit reflection is reflected back colored filter again by backlight again, recycles.
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Comprise red filter unit, green filter unit and blue filter unit for colored filter in the embodiment of the present invention, specifically introduce technical scheme of the present invention.But the filter unit combination of colored filter is not limited thereto, and can also comprise other filter units, as: Yellow filter unit, white filter unit.Certainly, the filter unit of colored filter also can realize the colored color combination shown for other.
Colored filter in the embodiment of the present invention comprises the filter unit of multiple transmission different colours light, the light that backlight sends is to colored filter, the light of each filter unit TEM investigation color, the light of reflection other color except corresponding color, the light of described filter unit reflection is reflected back colored filter again by backlight again, via the filter unit transmission of corresponding color, the light of filter unit not transmission can be recycled, thus improve the utilization ratio of light, reduce energy consumption.
In order to ensure display quality, the transmissivity >90% of described filter unit to corresponding color light is set, to the transmissivity <1% of other color light except corresponding color.
Relative to prior art, the present invention arranges the filter unit of colored filter while the light of TEM investigation color, the light of reflection other color except corresponding color, reflection ray is reflected back toward colored filter again, via the filter unit transmission of corresponding color, can recycle, improve the utilization ratio of light, reduce energy consumption.
Concrete, as shown in Figure 2, the colored filter 1 in the embodiment of the present invention comprises the blue filter unit 12 of the red filter unit 10 of transmit red light, the green filter unit 11 of transmit green and transmit blue.When the white light of backlight incides on colored filter 1, red filter unit 10 while transmit red light 1, reflect green light 2 and blue light 2.While green filter unit 11 transmit green 1, reflect red 2 and blue light 3.While blue filter unit 12 transmit blue 1, reflect red 3 and green glow 3.
For red filter unit 10, the principle that the light of filter unit reflection is re-used is:
Because backlight can change (such as: reflector plate plays reflex to light to the light path of light, diffusion sheet plays scattering process to light, prismatic lens plays refraction action to light and changes light path), make the green glow 2 that reflected by red filter unit 10 and blue light 2 are reflected back colored filter 1 by backlight again.Can not reflect according to former road after green glow 2 and blue light 2 are reflected by backlight, that is green glow 2 and blue light 2 have the probability of 2/3 to reenter to be mapped on red filter unit 10, such as incide green filter unit 11, so green glow 2 can transmission, and blue light 2 is reflected back toward backlight recycles.Even if green glow 2 and blue light 2 are back into being mapped on red filter unit 10, blue light 2 and green glow 2 also still can be continued to be recycled by reflection.
The principle that the light that green filter unit 11 reflects with blue filter unit 12 is re-used is identical with red filter unit 10, repeats no more.
According to above-mentioned principle, recycle because the ruddiness 2 and 3, green glow 2 and 3 and the blue light 2 and 3 that reflect obtain, thus improve the utilization ratio of light, reduce energy consumption.Compared to liquid crystal indicator of the prior art, light utilization ratio promotes 30%-60%.
Preferably, the transmissivity >90% of red filter unit 10 pairs of ruddiness is set, to the transmissivity <1% of green glow and blue light.The transmissivity >90% of green filter unit 11 pairs of green glows is set, to the transmissivity <1% of Red and blue light.The transmissivity >90% of blue filter unit 12 pairs of blue lights is set, to the transmissivity <1% of ruddiness and green glow.
