Abstract
The invention provides a display panel and a display device and belongs to the technical field of reflection type liquid crystal display. The display panel comprises an array substrate, a cassette-to-cassette substrate arranged opposite to the array substrate, and a reflection layer arranged on the side face, close to the cassette-to-cassette substrate, of the array substrate. Multiple lens units are arranged on the display face side of the cassette-to-cassette substrate. The lens units are used for enabling the incident angle of light irradiating the lens units to be smaller than a refraction angle. Due to the fact that the lens units are arranged on the display face side of the display panel, the incidence angle of the light becomes smaller, the utilization rate of the light can be increased, the reflection rate of the display panel is increased, and power consumption can be reduced.

Detailed description of the invention
For making those skilled in the art be more fully understood that technical scheme, knot below
Close the drawings and specific embodiments the present invention is described in further detail.
Embodiment 1:
Shown in Fig. 2-4, the present embodiment provides a kind of display floater, this display floater
For reflective display panel, specifically include array base palte 2 and with described array base palte 2 phase
To arrange to box substrate 1, be arranged on array base palte 2 near the described side to box substrate 1
Reflecting layer 21 on face, and it is additionally provided with many in the described display surface side to box substrate 1
Individual lens unit；Described lens unit is for making to expose to the incident angle of light thereon
Less than refraction angle, say, that by lens unit being incident to light box substrate 1
Time angle turn down.
Owing to the display surface side at the display floater of the present embodiment arranges lens unit, therefore
The incident angle making light diminishes, such that it is able to improve the utilization rate of light, increases display surface
The reflectance of plate, can reduce power consumption simultaneously.
Wherein, the present embodiment can be color membrane substrates 1 to box substrate 1.Certainly,
If color film layer is set on array base palte 2, can also be not provided with on box substrate 1
Color film layer.
Wherein, the display floater in the present embodiment can utilize nature light as light source.When
The most preferably, use display light source 3 as the light source of display floater.
Concrete, the display light source 3 in the present embodiment is arranged on the display to box substrate 1
Side, face, specifically includes LED lamp bar, and is arranged on described to box substrate 1 display surface side
Light guide plate 32；Wherein, the light that described LED lamp bar is sent can be through described leaded light
Plate 32 exposes to described lens unit.
Wherein, each described lens unit all includes a lenticule 4, now can be by
The rising angle of light guide plate 32 matches with the focal length of lens, such as by design light guide plate
32 go out the direction of light at-60 ° to 80 °, control the focal length of lenticule 4 at 50mm extremely simultaneously
During 100mm, (combined refractive index, thickness, and radius of curvature set light extraction efficiency maximum
Meter), from lenticule 4 light out, the least with the normal direction angle of display floater more
Good, i.e. angle is optimal when being 0 °.
It is to say, in the present embodiment, preferably pass the light through lens unit and irradiate
To during to box substrate 1, the incident direction of light such as collimates directional light.
Lenticule 4 can be spherical lens in the present embodiment, it is also possible to saturating for aspheric surface
Mirror (such as post lens, prism etc.), preferably lenticule 4 are spherical lens；For micro-
The selection of the focal length of lens: object focus selects on light guide plate 32, and i.e. light guide plate is apart from micro-
The focal length of lens 4 is D, and the focal length now selecting lenticule 4 is D；For preferably
The size Selection of lenticule 4 is in the same size with array base palte pixel region, and i.e. one micro-
The corresponding pixel region size of mirror 4.
Wherein, lens unit is battery of lens；It is multiple that described battery of lens includes that stacking is arranged
Sub-lenticule 4.Preferably, a pixel on the corresponding array base palte of each battery of lens 5
Area size.
Concrete, after light that LED lamp bar 31 is sent exposes to light guide plate 32, guide-lighting
Each position of plate 32, due to different from the distance between LED lamp bar 31, causes going out of light
Penetrate direction also to differ, as it is shown on figure 3, the territory, output optical zone of light guide plate 32 is divided into A,
Tetra-districts of B, C, D.Now, for the making below each light guide plate 32 zones of different
The battery of lens 5 of different parameters, so that light enters incident angle during box substrate 1 optimum.
And, when some region of light is with the incident battery of lens 5 of some angle, now, should
The angle of this light can be turned down by many sub-lenticulees in battery of lens 5.
Wherein, in order to display floater reaches lightening effect, each in the present embodiment
Many sub-lenticule composition Fresnel Lenses in mirror group.Wherein, mostly Fresnel Lenses is
By the thin slice of polyolefine material injection pressure, glass is also had to make, lens surface one side
For bright finish, the ascending concentric circular of another side imprinting, its texture is according to light
Interfere and disturb and penetrate and relative sensitivity and receiving angle requirement design.Wanting of lens
Ask the highest.The lens of a piece of high-quality must any surface finish, clean mark, its thickness with
Becoming on the way, how at about 1mm, characteristic is that area is big, thickness is thin and detecting distance is remote.
Therefore, it is not difficult to find out, uses Fresnel Lenses so that the display of the present embodiment
Panel is more lightening.
Preferably, the display floater of the present embodiment also includes unsymmetry scattering film layer 6；
This unsymmetry scattering film layer 6 is arranged on the incidence surface side of described lens unit, and being used for will
By being scattered that described reflecting layer 21 reflects.
Wherein, if display floater uses nature light as light source, unsymmetry scattering film layer
On the incidence surface side of 6 direct lens units, when natural light by unsymmetry scattering film, thoroughly
Mirror unit, the reflecting layer 21 exposed to after box substrate 1 on array base palte 2 is reflected
Lens unit is through unsymmetry scattering film layer 6 so that light scatters, wider array of to obtain
Visual angle.
If display floater uses display light source 3 as light source, unsymmetry scattering film layer
6 are arranged between lens unit and light guide plate 32, and its operation principle is identical with above-mentioned principle,
No longer describe in detail at this.
Certainly, the display floater of the present embodiment also includes polaroid 7.Polaroid 7
The exiting surface side of lens unit can be arranged on, it is also possible to be arranged on box substrate 1 with saturating
Between mirror unit.
Embodiment 2:
Providing a kind of display device in the present embodiment, it includes the display in embodiment 1
Panel.Therefore, the light utilization efficiency of the display device of the present embodiment is high, power consumption is relatively low.
This display device can be: Electronic Paper, mobile phone, panel computer, television set, aobvious
Show any products with display function such as device, notebook computer, DPF, navigator
Product or parts.
It is understood that the principle that embodiment of above is intended to be merely illustrative of the present
And the illustrative embodiments used, but the invention is not limited in this.For ability
For those of ordinary skill in territory, in the situation without departing from spirit and substance of the present invention
Under, various modification and improvement can be made, these modification and improvement are also considered as the present invention's
Protection domain.
