Abstract
An autostereoscopic display device comprises a display panel having an array of display pixels for producing a display, the display pixels being arranged in rows and columns; and an imaging arrangement for directing the output from different pixels to different spatial positions to enable a stereoscopic image to be viewed. The display panel and imaging arrangement are coupled together around a seal line, and a volume defined between the display panel, the imaging arrangement and the seal line has a reduced pressure. At least one of the display panel and the imaging arrangement is provided with a channel within the volume. This channel enables the volume defined to be increased in size but whilst maintaining a small spacing between the display panel and imaging arrangement. This increased volume means that the pressure will change less quickly in response to gas leakage across the seal line.

Backlight not shown in Fig. 5.
A kind of traditional approach of making the 3D display is to begin with complete 2D display apparatus module, and it is updated to the 3D display.
In order to make the structure shown in the assembly drawing 5 in this way, implement following step:
-by removing fixed mount 71 and dismounting electron device, from this 2D module dismounting 2D panel;
-this 2D panel is placed on the platform;
-use the lenticular array of use edge sealing to obtain the 3D panel;
-introduce the additional glass plate this panel can be squeezed between lenticular array and add-in card in this 3D panel back;
-this 3D panel sets is installed in the original 2D module, obtain the 3D module.
In this manufacturing process, run into problems:
-in the assembly and disassembly process of this display, electron device can be impaired;
-this manufacturing process expends time in and the labour very much;
-lenticular array only is installed to face plate edge, makes to be very difficult to guaranteed performance, because panel and biconvex lens can be crooked;
-display panel itself is may be unsatisfactory smooth and have Feng Hegu, and this makes and is difficult to guaranteed performance;
The needs of the add-in card of-3D panel back have increased system weight and have changed the thermal behavior of system, may cause performance change.
Therefore this dismounting and the method that re-assemblies exist many shortcomings.
The invention provides a kind of vacuum installation method, this method still can be adjusted standard 2D panel, makes thus and can use the display module that can be purchased off the shelf, but solved part the problems referred to above.
Fig. 6 is the process flow diagram of explanation assemble method of the present invention.
By cleaning 78 and use in step 79 and to be sealed to thin sheet surface and to handle lenticular sheet.The sealing line comprises charging door and around the lenticular sheet edge, makes it center on the viewing area in finished product.Sealing can change into and be applied to display panel side.It is 2 to 5mm thick that lenticular array is generally.
Handle the 2D display module in step 80 by removing fixed mount 71 from the 2D module.Yet, do not need to remove this dual panel display and disconnect the demonstration electron device thus.
After cleaning in step 82, in step 84, lenticular array is coupled in step 85 at aligning and two panels on the potted line.
In step 86, to using vacuum by the space of lenticular array, potted line and the definition of 2D panel.
In step 88, the charging door closure, and, solidify sealing in step 90.
This process make LCD panel and lenticular plate as far as possible near-earth be installed together, have the as far as possible little gap suitable therebetween with the Tolerance level of LCD panel and lenticular plate.Use potted line to mean that plate can't move after this technology is finished.Potted line is preferably curable fluids with the formation packing ring, and sealing is used for LCD panel and lenticular plate are coupled.
Vacuum is used to reduce the cavity size between LCD and the lenticular plate.By the air in the cavity of finding time, the volume of cavity reduces.
Preferably, the sealing line is extruded to the thick thickness of 50 to 100 μ m.When the spacing between LCD panel and the lenticular plate has reached desired spacing, stop to use vacuum.This spacing is less and in potted line place maximum, this spacing will increase to the size of 50 to 100 μ m at the potted line place at the center of viewing area.
Potted line can permeate by water and solidify; Perhaps can use the encapsulant of two kinds of compositions, application of temperature and/or UV driven are solidified.
As a result, two plates very closely are installed together.The existence of inside cavity vacuum is not required for retaining plate and fixes, and it is used as Alignment Process but not the part of technique for fixing.
This method has prevented in the assembly and disassembly process damage to electron device, because display no longer needs complete dismounting.Lenticular array and panel are closely installed on the whole active region of display by biconvex-inside and outside pressure differential of panel combination, and the gap homogeneity is provided thus.This method has been avoided the demand to other glass plate.
Check after the sealing that in step 92 use fixed mount 71 once more in step 94, this fixed mount 71 has been adjusted with adaptive additional lenticular array in step 96.
At last, use fender in step 98, and finished product can be fed to the assembling factory.
Fig. 7 illustrates mounting equipment of the present invention, uses the reference symbol identical with Fig. 5.Lenticular array represents that with 100 potted line is represented with 102, and adjusted fixed mount is represented with 71 '.
As mentioned above, the volume of application vacuum has very little volume.For example, the gap size on most of zone of display can be in 0 to 10 mu m range.940 * 530mm for potted line inside
2Area, the average thickness of 1 μ m, obtaining volume is 498mm
3Vacuum.
This vacuum produces the pressure differential on the potted line.For unfavorable sealing, this is as the driving force of nitrogen, oxygen and other gas infiltration vacuum area.The result is, depends on the perviousness of encapsulant, and vacuum level reduces very lentamente.
Although it is mechanically fixing that this installation comes by the sealing line, but this pressure variation can cause that spacing in time slightly changes, the particularly increase in gap between lenticular array and the panel plate.
The adjustment example of explaining with reference to figure 8 makes vacuum level owing to the speed that perviousness reduces significantly reduces.The result is that the increase speed in gap can significantly reduce between lenticular array and the display panel plate.This helps to increase the life-span of product.
As shown in Figure 8, the volume of vacuum space 110 increases by lane device 112, but does not increase length of sealing line.These passages can be considered as comprising vacuum buffer.
Produce the additional cushion spaces with the potted line adjacents of sealing 102 definition, this additional cushion space enlargement comprise the zone of vacuum.For example, with above-mentioned 498mm
3Vacuum space compare, suppose that the channel width and the degree of depth are 1mm, this volume can increase 2940mm
3This is increased to about 7 times.The result is that the influence of infiltration gas significantly reduces.
Above-mentioned example adopts the display panels of the display pixel pitch that for example has 50 μ m to 1000 μ m.Yet, it will be understood by those skilled in the art that the display panel that can adopt the alternative types such as Organic Light Emitting Diode (OLED) or cathode ray tube (CRT) display device.
The manufacturing and the material that are used to make display device and lenticular array are not described in detail, because these are traditional and are well known to those skilled in the art.
Various other adjustment are conspicuous to those skilled in the art.
