The implementation to each part of first embodiment is illustrated separately below.
First, lighting module
Lighting module includes at least two display panels and light-splitting device；At least two display panels are located at The both sides of light-splitting device, and with light-splitting device into predetermined angular；Preferably, at least two display panel With light-splitting device into 45 degree of angles.
Wherein, display panel display image, the image that light-splitting device conduction display panel is shown.
Alternatively, when display panel is non-self-luminous surface plate, lighting module also includes light source and convergence Mirror：Convergent mirror is located between light source and display panel, and the light that light source is launched is by convergent mirror to display Panel is illuminated.
Alternatively, when display panel is self-emission panel, e.g., OLED (Organic Light-Emitting Diode, Organic Light Emitting Diode) display panel, lighting module need not have attached Plus light source, light-splitting device transmission and reflection the light from self-emission panel.
Alternatively, when display panel is monochromatic self-emission panel, light-splitting device is band logical color dispersing Device：Band logical color dispersing device is reflected from monochromatic self-emission panel and same color Light, and transmit the light of other colors.
Preferably, at least two display panels to be to switch display image more than predetermined refresh frequency, and The image that each display panel is shown is in predetermined ratio pixel of both horizontally and vertically interlocking.For example, By two display panels to switch display image more than predetermined refresh frequency, and each display panel Image both horizontally and vertically interlock 1/2 pixel, then resolution ratio can be doubled.
It is highly preferred that when the number of display panel is n, n display panel is with more than n × 30Hz Frequency switch display image, and the image that each display panel is shown both horizontally and vertically handing over Wrong 1/n pixel.For example, n display panel switches display image with n × 60Hz frequency, So that the imperceptible flicker of human eye.
Lighting module in the present embodiment includes any implementation：
Scheme one：Lighting module has used polylith display panel, and polylith display panel is positioned over optical splitter Part surrounding, and with light-splitting device into predetermined angular, for example, into 45 degree of angles.As shown in Figure 5 a, Display panel can be two pieces, and light-splitting device can be polarization spectroscope.Polarized light splitting device reflection comes The light of the first polarization direction component after from being collimated by convergent mirror of light source, and transmit orthogonal to that Second of polarization direction component light, transmission and reflection polarization direction light be used for non-self-luminous surface The illumination of plate.
After the illumination light of light source is by convergent mirror, collimate as directional light, with polarization spectroscope into 45 degree Angle directive polarization spectroscope.The light of first polarization state in illumination light is reflexed to display surface by polarization spectroscope Plate 1, is that display panel 1 provides illumination light, by the light transmission of the second polarization state to display panel 2, Illumination light is provided for display panel 2.The light of first polarization state is changed into the after the reflection of display panel 1 The light of two polarization states, carries display image information, for example, the image that display panel 1 is shown, passes through Polarization spectroscope is transmitted away.It is inclined that the light of second polarization state becomes first after the reflection of display panel 2 The light of polarization state, carries display image information, for example, the image that display panel 2 is shown, by polarization Dichroic mirror is gone out.
In the present embodiment, by using two pieces of display panels and polarization spectroscope, the illumination from light source Light will not be reflected back toward light source position or be scattered, and all light are all used to irradiate display panel and carry Subsequent optical path is supplied, so that the utilization ratio of illumination light is effectively improved, than using in the prior art The method of scattering film scattered portion illumination light reduces the loss of light, reduces energy consumption, can be effectively Improve the cruising time of device battery.
Two pieces of time-multiplexed methods of display panel are specific as follows, utilize two pieces of display panel display images Content, two display panels are to switch display image, predetermined refresh frequency more than predetermined refresh frequency The refreshing frequency that human eye can be differentiated is exceeded well over, for example, predetermined refresh frequency is more than 2 × 30Hz=60Hz, Simultaneously display image both horizontally and vertically all interlock half of display panel pixel distance, so Human eye is in synthesis, and the resolution ratio of display image will increase twice.N blocks display panel is time-multiplexed Method And Principle it is similar with two pieces of time-multiplexed methods of display panel, the predetermined refresh frequency of every piece of panel Rate be more than n × 30Hz, and every piece of display panel image both horizontally and vertically interlock 1/n picture Element, thus image resolution ratio will n times of improve.
In this programme, display image is on the one hand improved using the time-multiplexed method of polylith display panel Resolution ratio, it is possible to provide good display quality, on the other hand also take full advantage of illumination light, improve The utilization ratio of illumination light.
Scheme two：Lighting module uses polylith display panel, and polylith display panel is positioned over light-splitting device Surrounding, and with light-splitting device into 45 degree of angles.Light-splitting device is used only without using polarization spectroscope Common spectroscope, can be two pieces shown here as panel as shown in Figure 5 b, light-splitting device can be Common spectroscope.
After the illumination light of light source is by convergent mirror, collimation turns into directional light, with spectroscope into 45 degree of angles Directive spectroscope.A part of light is reflected to display panel 1, is that display panel 1 provides illumination light, Another part light transmission, to display panel 2, is that display panel 2 provides illumination light.Illumination light is by aobvious Show that panel 1 reflects, carry the display image information of image, transmitted by spectroscope, into light conduction Unit；Another part illumination light reflects by display panel 2, carries the display image information of image, Entered dichroic mirror, into light conduction cell.Thus, the resolution ratio of display image is as with top Be will be enhanced in case one using time-multiplexed method, but the utilization ratio of illumination light can be less than with Upper scheme one.
