Description

[Detailed Description of the Invention] This relates to the four-projection type, Shinjimanso, and the power module.

Conventionally, projection type display devices have been used for protection, tp, ・i5 ri,

For No. I, it was unnecessary to watch the entire +('j image) online.On the other hand, Projection TV i,
t, cRT (bmoζun #'i)-'F:nomoni:) is a method that was born from the fact that there are major constraints on the size of a 26-inch or larger screen. However, CRT
The brightness of the CRT is quite safe because of the emitted light sound No. 11, so it is a very large system that uses a special (3 ft T'i) electric power and is used for cooling, so it can be easily installed in the home. There were 9 drawbacks such as difficulty in waiting.Father, the original screen was insufficient, the brightness on the screen was insufficient, and the screen position and system position were adjusted due to the compositing on the %6V original screen. Even with the L7 adjustment, the colors tended to shift on the screen, and the overall quality was extremely poor, making the screen quite difficult to view.Also, the system was special and the large CRT+
, special electromagnetic images, and adjustment threads, making it quite expensive. As a result of these efforts, the advantages of large screen televisions or projection televisions have not been fully utilized and their widespread use has been delayed.

Therefore, the present invention eliminates this awkward entry point and provides a system that is easy to handle, has a compact system, and allows each person to express one flexural case. 'i
% Xinjing's OU is using a transparent custom order.

The image on the liquid crystal surface is projected onto the entire screen.

FIG. 1 is a diagram showing the principle of the present invention, and is a one-panel system.

A light source 1, a lens 2.4, and a screen 75 are connected to each other, and a liquid crystal pile 6 is arranged to form an image. The lens, light source, and optical system of the screen device perform the same functions.
omitted. The variation before addition is shown in the example. The liquid crystal panel 5 is of the OctoT IQ (Lyslad Nematic) type, and the biasing plate 7.8 is the panel "k?".
I'm in Yosan. The liquid crystal panel consists of a glass plate sandwiched with liquid crystal material.
40. Fully control its transmittance. In other words, it is used as a liquid crystal shutter.

The color filter 6 is a type that displays a color image, and may be formed on the inner surface of the panel, or may be formed on the polarizing plate 7.
Even if you place it on the light source side, it will still be visible to the public. This universal feature is that the optical system consists of a light source consisting of a simple lamp, a lens, and a screen that can be easily removed, and the liquid crystal panel is originally very low in ICl), so the system is compact and low-cost. It is affordable and at the same time very easy to handle. For example, even if the distance from the lens 4 to the screen changes by 5 degrees, focusing can be easily performed using the lens 4 in the method described above.

It can be arbitrarily selected by changing the focal length of the lens 4 by 1ηW'ft to the father screen size. This is a conventional projection CRT
'''CR Yufu is an impossible feature.

FIG. 2 shows an example of the structure of a liquid crystal panel used in the present invention.

Normally, it is difficult to increase the number of pixels in liquid crystals, and as a result, the number of scanning lines used was small, and the resolution had to be degraded.
This drawback has been completely solved by the active matrix method shown in (b).

The timing acid 12 corresponding to the scanning line turns on the transistor 10, and the display data is written to the liquid crystal drive electrodes 11 arranged in both systems through the data binding 13. After that, the transistor 10 becomes 011'F[.

Even if the display data is written -1fi, the 11% display data is retained and the liquid crystal is fully driven. Since the transistor 10 used here must be formed on a transparent substrate, a polycrystalline or amorphous silicon thin film transistor (TPT) is used. (B) is a cross-sectional view of a liquid crystal panel using TPT, in which TNT is mounted on a glass substrate 16 and drive electrodes 19 are formed. Also, drive on the same glass 15'
R, the pole 2o is formed, and the liquid crystal material 18 is sealed with the sealant 17. On the other hand, the color filter is formed of 6JIx color filter scraps 21 of red, blue, and green on the glass substrate 14, and is aligned with the drive electrode 19. (c) is another configuration example of a panel using TPT, in which a filter layer 22 and a drive electrode 26 are formed on the same glass 15, and the feature of this method is that a color filter is placed on the circular surface of the liquid crystal panel. Because layers are formed,
Even if the angle of incidence of the incident light changes more or less, it will not cause color distortion, and the parallelism of the incident light will shift, making it difficult to use even simple scattered light.

In principle, this method will expand the number of original LCD panels by 7N, so it will be possible to expand the number of original LCD panels. ! ;l quotient lamp is required. As a result, 116 degrees t on the panel surface is very different, 100,000 tx ~ 5o J5
tx.

On the other hand, since TPT is a semiconductor, eJ1 electromotive force is generated in response to light, and even if the transistor is in the OFF state, the charging current approaches the ON state, and the contrast of the display screen decreases. Significantly decreased.

Normally, the illumination intensity at which this decrease in contrast begins is about 100,000 Ax for white light, and in terms of wavelengths of light, the long wavelength side, that is, the red to infrared range is the most popular range. Contrast decrease due to this bias? A means to prevent this is to place a color filter on the commercially available material as a light source decoy, and to move the glass substrate on which the TPT is mounted from the liquid crystal material to the side opposite to the light source. As a result, since light always enters the TPT surface through all the color filters, blue and green are equiaxed [1/1
Since the archetype below 0, and even red light, is reduced to 115 d)k, the induction of light flow in TF'T in the layer due to intense light incidence is suppressed, and the contrast of the image decreases (-becomes difficult to see). This phenomenon can be prevented. Figure 3 shows an example of the configuration of a thin image display module used in the substitute panel used in the present invention, and (A) is a plan view, and (CD)
(c) is a front view of Ifu, and (d) is a cross-sectional view of the connection between the panel and the board. LCD panel is TI
It is made up of a transparent substrate 54% on which all FTs are mounted, a transparent substrate 52 on which all color filters are mounted, a sealing material 66, and a liquid crystal material 37, and an input terminal for driving all 1TFT on the T and FT substrate 34? A pole 40 is formed. On the other hand, the circuit board 6o ((1) receives the input signal 1g from the human power connector section 43, and connects the circuit components 55 such as ICs and chip components that are essential for driving the TPT panel. As well as mounting (4 (%) No. 4J (1) outputted from the circuit (1 output terminal 59, conductive rubber, 4 tons paste).

The IU contact voltage is input to the input terminal of the TPT board: F electric box 40 by the first stage of the corpse in contact with the gold bump float. Also, if necessary, molding agent 53 t) is used.The feature of this method is that the transparent substrate 32 above the panel is attached to the frame 351-' of the circuit board 30.
J °t is 9 people, 9 included, nt, and then (d) to the back f, times i! From the 46th board, TF on the F side is 1 to 34.
So, the thickness of the display module is
The thickness of the circuit board and the lower TF'f' board is reduced by 1 and 2, making it as thin as possible.
It is foiIi. Also, due to the overlapping of the substrate and glass, S) a nice flat surface (panel-e-:) :x--hyl, (c) K7. Once the coat 42 of film is formed, it can be easily removed and rolled.

This method requires 91. At the same time, by increasing the number of pixels tdA, it is possible to prevent the deterioration of image quality due to the inclusion of noise and noise between the two. Assuming a color-clothed bobanel, the input is 4 degrees, 1 g, and 3.
It is also possible to install R, G, i3's self, 1 flight control, 2-shu board t, by combining human power and control, and by manpowering only bidet No. 13. Ru. Also, if the display is black and white, the bidet No. 1g can be moved only by human power (4 degrees, 4 degrees).
