Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a display device for a novel electronic device or the like. More specifically, it is a display device consisting of a plurality of stacked 7 (G) crystal plates, and by switching the liquid crystal plate or combination of liquid crystal plates for display, the display always corresponds to the mode of the electronic device, etc. The purpose of the present invention is to provide a display bag 4 for 11 types of electronic devices, etc., which can be used to display devices, and furthermore, a transparent switch layer is layered on the surface of the display device, and the switch can be attached to the display bag. It is an object of the present invention to provide a novel display bag for electronic equipment, etc., in which the element is compatible with a display using a liquid crystal panel.

BACKGROUND TECHNOLOGY AND PROBLEMS Video cheap recorders originally have a variety of functions, but there is a demand for an even greater variety of functions. By the way, when the functions are increased, the number of operation switches must be increased accordingly, and the number of displays showing the operation switches must also be increased. On the other hand, video tape recorders are required to be smaller, especially thinner, and there is a restriction on increasing the width of the iE surface on which the display section and operation switches are written. Therefore, it is difficult to arrange all of the necessary display sections and operation switches within the front panel of the video chip recorder, making it extremely difficult to meet the demands of increasing the functionality and making the device thinner. .

Furthermore, since the video tape recorder has a wide range of functions and a large number of display and operation switches, there is also the problem that it is easy to get confused about the operation or become confused about the correct way to operate it. Therefore, it is difficult to operate the video tape recorder accurately and quickly if you are not used to operating the entire culm, especially those who are weak in so-called mechanical and electrical equipment (mostly elderly people and women) may not be able to operate it at all. This can be said to be the actual situation. This means that even though the displays and operation switches that need to be viewed and operated differ depending on the mode of the video tape recorder, all of the displays and operation switches that are necessary for all modes are always available at the same time. It is thought that l/X is due to the presence of the iE plane. That is, the modes of the video cheap recorder include playback mode, recording mode, answering machine setting mode, etc., and when in playback mode, for example, various switches such as channel setting switch, answering machine setting switch, etc. Display t± exists even though there is no need to operate or see it, so
There is a possibility of erroneous operation, and this is thought to be a major cause of erroneous operation. However, this has not been pointed out in the past, and therefore no consideration has been given to it.

Purpose of the Invention Therefore, the present invention aims to provide a novel display device for electronic equipment, etc., which can always display a display corresponding to the mode of the electronic equipment, etc. It is an object of the present invention to provide a novel display device for electronic equipment, etc., which has improved operability by laminating transparent switch plates so that each switch element corresponds to the above-mentioned display.

SUMMARY OF THE INVENTION In order to achieve the above object, the f51 display device for electronic equipment, etc. of the present invention is constructed by laminating a plurality of liquid crystal plates that display a shape corresponding to the control content. You can change the combination of LCD panels displayed,
A second display device for electronic equipment, etc. of the present invention is characterized in that a predetermined display is made by one or more liquid crystal panels in a display state. It consists of stacking multiple liquid crystal panels that display a shape corresponding to the content, and then superimposing a transparent switch board with multiple switch elements on top of the stacked liquid crystal panels.
The liquid crystal plate to be displayed or the combination of liquid crystal plates to be displayed can be changed, and a predetermined display can be made by one or more liquid crystal plates in the display state, and further,
The display is displayed using the transparent switch 1. It is characterized by being made to correspond to the switch element of the chip board.

EMBODIMENTS Below, a display device for an electronic device or the like according to the present invention will be described in detail according to embodiments shown in the accompanying drawings.

The drawings illustrate an embodiment in which the present invention is applied to a video tape recorder.

FIG. 1 is an exploded view of a display section l installed on the front panel of a video tape recorder.

2 is a horizontally long plate-shaped transparent electrode switch plate.

We are looking at the internal structure as shown in Figure 2. The transparent electrode switch board 2 is made by laminating and integrating transparent wiring boards 3 and 4 through a rectangular frame 5 at their periphery, and a transparent recording film is provided on the mutually opposing surfaces of the transparent wiring boards 3 and 4. 6.6
,... are formed. The wiring ■9.6.6, misfortune... 6a to 61 are wiring films extending in the vertical direction formed on the back side of the transparent wiring board 3 on the front side, with appropriate intervals from the left side to the right side. It is arranged. Among them, the wiring films 6e and 6f extend from the lower end of the wiring board 3 and have a length corresponding to approximately one third of the width of the wiring board 3, and the remaining films 6a to 6d and 6g to 61 extend from the lower end of the wiring board 3. It has a length that almost completely traverses 3. Further, 6j to 6p are wiring ■9 formed on the front side of the transparent wiring board 4 on the back side, and 6j,
6k and 6t are wiring films extending from the left end to the right side of the transparent wiring board 4, and are arranged at regular intervals from the upper side to the lower side.

The wiring film 6j on the second side has a length corresponding to about one half of the length of the wiring board 4, and the length of the wiring film 6h is about nine minutes of the length of the transparent wiring board 4. 1, and the lower wiring II! i! 61 has a length corresponding to about two-thirds of the length of the wiring board. 6m to 6p are wiring films extending from the right end of the transparent wiring board 4 to the left side,
Each has a length corresponding to about one-third of the length of the transparent wiring board 4, and is arranged at regular intervals from the upper side to the lower side. When viewed from the front side, the wiring film 6a is orthogonal to the wiring films 6j, 6k, and 6t, and the wiring film 6b and 6C16 are perpendicular to each other.
d is arrangement 9. Its! 6 j and 6L, and the arrangement n*6e and 6f are wiring IP! It is perpendicular to 61.

Similarly, the wiring films 6g, 6h, and 61 are arranged respectively)9.
There is one white intersection with n<:6m, 6n, and 60.6p.

By the way, the transparent wiring board 3 on the front side has lost its appropriate flexibility, so that when you press it from the front with your finger, it bends and the pressed part comes into contact with the wiring 4 on the back side. . Therefore, when the transparent wiring board 3 is pressed at a position corresponding to the orthogonal location between the wiring films 6.6, . . . 9 of the transparent wiring board on the front side and the transparent wiring films 6.6, . . . on the rear side, Wiring II intersects at the relevant location! ,! 6.6 contacts each other and are electrically connected. Thus, each intersecting portion of the wiring film 6 when viewed from the front side becomes a contact point and functions as a switching element of the transparent electrode switch plate 2. All of the wiring films 6a to 6p are connected to an input circuit of a microcomputer, which will be described later.

Reference numeral 7 denotes a transparent protection plate arranged on the back side of the transparent electrode switch 2. When the transparent electrode switch plate 2 is pressed from the front, the pressing force acts on the multicolor laminated liquid crystal section 8 on the back side, which will be described later. It is a useless thing to prevent it from being destroyed.

The multicolor laminated liquid crystal section 8 includes four color polarizing plates 9B, 9Y, 9.

, to2.9M, and 103.9R.

Color polarizing plates 9B, 9Y, 9M and 9R are transparent when no voltage is applied between electrodes (not shown), and when voltage is applied, 9B is blue, 9Y is yellow, 9M is milky white, and 9R is red. It is designed to transmit light. Liquid crystal board 10. ．． 102.103 is, for example, TN (
TWI ST NEMATIC) type, transparent wiring films are formed on both the front and back sides, and the wiring film on one side is one common wiring film formed to cover almost the entire surface.For example, While it is grounded, the pattern wiring film on the other side has a large number of wires, each with a predetermined shape, and when a predetermined drive voltage is applied between it and the ground, the pattern wiring film receives the drive voltage. A portion between the wiring film and the common wiring film (ie, a portion where an electric field is generated) has a light-shielding property. The portion of the liquid crystal plate 10 where no electric field is generated has light transmittance. Therefore, by appropriately changing the pattern wiring film to which a driving voltage is applied between the common wiring film and the common wiring film, various displays can be displayed on the liquid crystal plate IO. In other words, this means that the shape of the display on the liquid crystal plate 10 can be changed depending on the content of the control signal given to the liquid crystal plate 10.

Moreover, the liquid crystal plate 10 to display or the liquid crystal plate 1 to display
The shape and color of the display obtained from the entire multicolor laminated liquid crystal section 8 by changing the combination of 0.10, . . . and changing the color polarizing plate 9.9, . can be changed more complexly.

11 is a light guide plate placed behind the multicolor laminated liquid crystal section 8;
It serves as a surface light source to obtain display light. Reference numeral 12 denotes a lamp placement hole formed approximately in the center of one end surface of the light guide plate 11. A lamp 13 is placed inside the lamp placement hole 12, and most of the light projected from the lamp 13 is guided. The light travels through the light plate 11 and is reflected on the back side of the light plate 11 toward the hemostasis side to become display light that contributes to display.

FIG. 3 shows a control circuit 14 consisting of a microcomputer provided in the video recorder.

In the figure, 15 is a key input circuit, which is connected to the wiring films 6a to 6p of the transparent electrode switch board 2, and is opened from the front of the switch element (or switch contact) of the transparent electrode switch board 2. Wiring film 6.6,...
- When the location where the keys intersect is pressed, a corresponding key input signal is input to the key input circuit 13. Reference numeral 16 denotes a mode determination circuit which, upon receiving a signal from the key input circuit 15, determines what state the multilayer liquid crystal display section 8 and the video tape recorder system should be placed in according to the content of the signal. Reference numeral 17 denotes a liquid crystal control circuit, which inputs the signal related to the multicolor laminated liquid crystal section 8 among the discrimination signals from the mode discrimination circuit 16, creates a control signal for controlling the multicolor laminated liquid crystal section 8, and sends it to the control circuit. 14 is sent to an external liquid crystal drive circuit 18. Reference numeral 19 denotes a system control circuit which takes in signals relating to the status of each part in the video cheap recorder from among the discrimination signals from the mode discrimination circuit 16, and sends a control signal to each part in the video tape recorder. 20 is an oscillator that generates a control clock pulse that controls each circuit in the microcomputer;
In addition to the clock pulse, a low frequency clock pulse for driving the liquid crystal is also generated and sent to the liquid crystal driving circuit 18.
