Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a small information processing device in which a display section for displaying information is connected to a main body using an instruction hinge section as a fulcrum and can be opened and closed. The present invention relates to a small-sized information processing device that can confirm display contents regardless of the situation.

[Conventional technology]

Conventional personal computers and Japanese word processors are increasingly taking on the form of laptops, using flat display devices such as liquid crystals for their displays, with the aim of reducing the footprint and increasing portability.

FIG. 2 shows the general appearance of these small information processing devices, and FIG. 3 does not show a block diagram.

In FIG. 2, a display section 1 is built into a lid 2, and the lid 2 is connected to a main body 4 using a support hinge section 3 as a fulcrum. A keyboard section 5 for inputting information is arranged on the top surface of the main body 4. As shown in FIG. 3, information input from the keyboard section 5 is processed by the arithmetic processing section 6 built into the main body 4 or the lid 2 shown in FIG. 2, and displayed on the display section 1. The feature of this device is that the lid 2 can be opened and closed by the hinge part 3. Even if the display part 1 with a relatively large area is used, the lid 2 can be closed when not in use, making it thin and easy to transport. This makes storage easier. Related devices of this type include, for example, Japanese Unexamined Patent Publication No. 62-31
Publication No. 826 and the like can be mentioned.

FIG. 4 shows the appearance of another small information processing device,
FIG. 5 shows a block diagram. In this conventional example, the display section 1 described in the conventional example is arranged on the top surface of the main body 4, similar to the keyboard section 5, and information input from the keyboard section 5 is processed by the arithmetic processing section 6 built in the main body 4. , is displayed on the display section 1.

Unlike the conventional technology, when the display unit 1 has a relatively small screen, the configuration shown in the present technology is adopted, and its feature is that the displayed content can be checked at all times because there is no lid. Related devices of this type include, for example, Utility Model Application No. 60-647
Publication No.

[Invention or problem to be solved]

In the above conventional technology, if the area of the display is large, it must be built into the lid and the lid can be opened when in use, and the display content cannot be checked when the lid is closed due to its thin shape. Moreover, when the display section is placed on the top surface of the main body without using a lid, there is a problem that a small display section must be used.

An object of the present invention is to provide a small-sized information processing device in which display contents can be checked regardless of whether the display section built into the lid is opened or closed, even if a large-area display section is used.

Furthermore, it is an object of the present invention to provide a device in which information can be inputted even when the lid is closed in a small information processing device, and to provide a device that allows the display unit to consume less power, which is an important condition in a small information processing device. .

[Means to solve the problem]

In the present invention, in order to achieve the purpose of making it possible to check the display contents whether the lid is opened or closed, the display section is constructed of a light-transmissive panel, and the support hinge section that supports the lid in which the display section is built-in is constructed. Lid opening/closing detection means for detecting the open/closed state of the lid is provided in the vicinity of the lid opening/closing state, and display reversing means is provided for displaying display information in a vertically inverted manner on one display section. Furthermore, a translucent panel for switching between cloudy and transparent was provided on both sides or one side of the light transmitting panel of the display section, in whole or in part. Alternatively, the apparatus is provided with a display section moving means for sliding the lid containing the display section relative to the main body.

Furthermore, in order to achieve the purpose of making it possible to input information when the lid is closed, the device has a light-transmissive seat for inputting information on a part of the upper surface of the light-transmissive panel constituting the display section or on the entire surface of the light-transmissive panel. A seed input means was provided.

Further, in order to achieve the purpose of low power consumption, the device is provided with a non-display means for hiding part of the display section.

[Effect]

By configuring the display section with a light-transmissive panel, the displayed information can be checked from both the front and back sides, and the display reversing means uses the amount detection information from the lid opening/closing detection means to display the upper and lower sides of the lid when it is closed. On the other hand, since the information is displayed in reverse, the displayed information can be checked from the front of the information processing device in the normal direction regardless of whether the lid is opened or closed. In addition, when the lid is closed, the semi-transparent panel provided on the top surface of the display light-transmissive panel is transparent when closed and does not interfere with confirmation of displayed information, and does not become cloudy when opened, depending on the opening/closing information from the lid opening/closing detection means. This makes it easier to confirm displayed information.

Further, when the lid and the main body are connected using the display section moving means, the display surface of the display section faces the front of the device both when it is closed and when it is opened, so that the displayed contents can be checked at all times.

In addition, since the coordinate input means provided on the top surface of the display section, which is made up of a light-transmissive panel, is light-transmissive when it is closed, it does not interfere with checking the displayed information on the display section, and the keyboard section located on the main body can also be checked. Therefore, information input can be easily realized.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of a compact information processing device according to an embodiment of the present invention, in which a keyboard section 5. The arithmetic processing unit 6 is
As in the conventional example, it is a means for inputting information and a means for processing information. Reference numeral 501 denotes a coordinate input unit installed on the surface of the display unit 1, which outputs the coordinates by touching it with a finger or the like. 5
02 is for pseudo-converting the coordinate information obtained from the coordinate input unit into keyboard information, and the conversion is realized by setting a conversion rule between the coordinate position and keyboard data in advance. Reference numeral 201 detects the opening/closing of the lid containing the display section 1, and the detected information is sent to the display reversing section 1o1° semi-transparent panel 102. The display inversion unit 101 inverts the display on the display unit 1 upward and downward based on information from the lid opening/closing detection unit 201. The semi-transparent panel 102 reflects light and
Light transmission is switched based on information from the lid opening/closing detection section. The display unit 1 uses a light-transmissive flat panel display, and displays display information from the arithmetic processing unit 6, display contents, etc.
The image is displayed through a display inversion section 101 that inverts the image downward. 6 and 7 show perspective views of the small information processing device based on this embodiment, with FIG. 6 showing the lid 2 in an open state and FIG. 7 showing the lid 2 in a closed state, respectively. When the M2 is in the open state, as shown in FIG. 102. As shown in FIG. 8, the light-transmissive display panel I is
Taking as an example a case where a dot matrix type liquid crystal display panel is used, which performs display by selecting and non-selecting the intersections of the respective electrodes in the X direction and the Y direction, the lid opening/closing detection section 2011 and the display reversing section 101 are used.
2. The operation leading to the display section 1 will be explained. In FIG. 8, the display data sent from the arithmetic processing unit 6 is transmitted to the X electrode driver 11.
0. The signals are input to a display controller 117 that generates timing signals and display signals for the Y electrode driver 111.

The display controller 117 sends a display signal 1132, a display latch clock, and a line latch clock 115 to the X electrode driver 110. FIG. 9 shows a timing chart of these signals, and the display signal 113 is sent out in arbitrary dot units so that it can be latched at the falling edge of the display latch clock 114. Data corresponding to the number of X electrodes,
That is, after sending out the data for -line, the line latch clock 115 is sent out in order to send out the data for -line from the X electrode driver 110 to the liquid crystal panel 112. Further, the display controller 117 is connected to the Y electrode driver 11.
1, whereas the line latch clock 115. The first line signal 116 is sent out. Line latch clock 115 is X
This is the same as that sent to the electrode driver 110. That is, the X electrode driver 110 and the Y electrode driver 111 are synchronized by the line latch clock 115.

As shown in FIG. 9, when the transmission of the display signal 113 is finished,
It sends out the line latch clock 115 and also sends out the first line signal 116. The Y electrode driver 111 latches the first line signal 116 at the falling edge of the line latch clock 115, selects the first Y electrode, and displays the liquid crystal panel 1.
Send on 12th.

In the liquid crystal panel, only the pixel at the intersection where both the X electrode and the Y electrode are selected lights up to realize a display operation.

Thereafter, display signals for - lines are sequentially transferred to the X electrode driver 110, and the Y electrode driver 111 shifts the first line signal 116 transferred at the end of the first line at the falling edge of the line latch clock. In this way, the Y electrodes are sequentially scanned. By this operation, the display information from the arithmetic processing section 6 is displayed on the display section 1.

Detection information from the lid opening/closing detection section 201 shown in FIG. 8 is sent to the display reversing section 101. For example, when an LSI (Large Scale Integrated Circuit) rHD66107TJ manufactured by Hitachi is used as the Y electrode driver 111 in the figure, the LSI can change the shift direction of the first line signal 116 depending on the level of the shift direction signal. Figure 10 shows HD66
This is a schematic diagram of the internal block diagram of 107T.
The electrodes 127, 128, 129 are simplified to three.

As shown in the figure, if the selectors 121, 1, 22, and 123 select the upper signal of their respective two input signals when the shift direction signal 118 is at the "H" level, then the first line signal 116 is The signal passes through the selector 121 and is input to the latch 124.

The latch 124 latches the input signal at the falling edge of the line latch clock 115 and outputs it to the Y electrode 127, passes through the selector 122, and outputs it to the latch 125.

Thereafter, similarly, every time the falling edge of the line latch clock 115 is input, the leading line signal 116 is shifted downward in the figure. In addition, the shift direction signal 11
When 8 is at "L" level, selectors 121, 122, 12
3, if the lower signal of the two input signals is selected, the first line signal 116 is selected by the selector 123.
and is input to the latch 126. The latch 126 latches the input signal at the falling edge of the line latch clock 115, outputs it to the Y electrode 129, passes through the selector 122, and outputs it to the latch 125. Thereafter, the leading line signal 116 is similarly shifted upward in the figure every time the falling edge of the line latch clock 115 is input. In this way, the shift direction signal 118 is
” level, the Y electrodes are selected sequentially from top to bottom in the diagram, and when “L” level, the Y electrodes are selected from bottom to top.
They will be selected in sequence.

That is, if the display signal 113 sent to the X electrode driver 110 shown in FIG. 8 is data 131, 132, 133, and 134 of each line as shown in FIG. When is at “H” level, Y
The shift direction signal 118 of the electrode driver 111 passes through the display inversion section 101 and becomes "H" level, and the data 141, 142, 143, and 144 can be displayed. Also, the detection information from the lid opening/closing detection unit 201 is “L”.
'' level, the shift direction signal 118 of the Y electrode driver 111 passes through the display inversion section and becomes the ``LJ level'', and as shown in FIG. Line data 151, 152, 1
53,154 can be displayed. This operation is shown in Figures 6 and 7.
If applied to Fig. 6, that is, when the lid 2 is in the open state,
Detection information from the lid open/close detector 201 indicates the open state.
The HJ level is reached, and the normal rotation image is displayed on the display unit 1 as shown in FIG. 12(a), and as shown in FIG.
When the lid 2 is in the closed state, the detection information from the lid detection section 201 is at the "L" level indicating the closed state, and the display section l shows the 12th
As shown in FIG. 7(b), an image inverted upward and downward is displayed, and if the keyboard section 5 in FIG. 7 is installed in front, the operator can see the image as a normal rotation image.

Moreover, the semi-transparent panel 10 shown in FIGS. 1, 6, and 7
2 improves the visibility of the display section 1 when the lid 2 is opened and closed;
Switch between light transmission state and light reflection state. As shown in FIG. 6, when the lid 2 is open, the semi-transparent panel 102 is in a light reflecting state, preventing light from passing through from the right side of FIG. 6, and as shown in FIG. In the closed state, the semi-transparent panel 102 is in a light-transmitting state and operates so as not to obstruct the view of the display unit 1 shown in FIG. 7. Specific examples of the semi-transparent panel 102 include, for example, a liquid crystal phase change (PC) effect using an electro-optic effect,
Also LCD guest host (Guest Ho5t
: GH) Effective. According to "Latest Technology of Liquid Crystals" (Matsumoto et al., Published by Kogyo Kenkyukai, 1983), PC effect liquid crystals allow incident light to pass through the liquid crystal layer when no electric field is applied, as shown in Figure 13. In the meantime, the light becomes scattered and the appearance becomes cloudy (Fig. 13(a)). Furthermore, when an electric field of a certain strength or higher is applied, the long axes of the liquid crystal molecules 161 are rearranged parallel to the direction of the electric field, allowing incident light to pass through without being scattered, and the appearance becomes transparent. In addition, as shown in Figure 14, the GH effect liquid crystal
When no electric field is applied, the vibration direction of the white linearly polarized light from the polarizer 162 and the light absorption axis of the dye molecule 164 coincide, so light absorption occurs and the transmitted light is colored (FIG. 14(a)). On the other hand, when an electric field is applied, the vibration direction of the linearly polarized light is perpendicular to the optical absorption axis of the dye, so in principle no light absorption occurs and the transmitted light is hardly colored. The PC effect and the GH effect can be switched between a light transmitting state and a light reflecting state by applying/not applying an electric field.

Therefore, in FIG. 6 (lid 2 open state), the lid opening/closing detection section 201
Based on the detection information from the transflective panel 1゜2, regardless of whether it is a PC effect liquid crystal or GH effect liquid crystal, by applying no electric field, the semi-transparent panel 1゜2 enters a light reflecting state, and Fig. 7 (lid 2 closed state)
Then, by applying an electric field to the semi-transparent panel 102 based on the detection information from the lid opening/closing detection section 201, the semi-transparent panel 102 becomes a light transmitting state, so that whether the lid 2 is opened or closed, the visibility of the display section 1 is not hindered, but is enhanced. It works like this.

Returning again to FIGS. 6 and 7 of this embodiment, the keyboard section 5, the light scattering plate 103. The coordinate input section 501 will be described in detail.

When the lid 2 is closed as shown in FIG. 7, the semi-transparent panel 102 is in a light transmitting state and does not interfere with the visibility of the display section.

Furthermore, since the display section 1 is also of a light transmitting type, a material that reflects light is required under the display section 1 in order to improve the visibility of the displayed image on the display section 1. Therefore, in this embodiment, as shown in FIGS. 6 and 7, a light scattering plate 103 is arranged at the upper back of the main body 1.

As a specific example of the light scattering plate 103, for example, even if it is a simple white plate, the purpose can be achieved. The coordinate input unit 501 is generally a transmissive type in which transparent electrodes intersect vertically and horizontally, and coordinates can be detected using principles such as pressure, electrostatic coupling, and electromagnetic induction using a pen-like coordinate support. It consists of a coordinate recognition device, and becomes effective when the lid 2 is closed, as shown in FIG. That is, when viewed from the operator, the coordinate input unit 501. Since the semi-transparent panel 1022 and the display section 1 transmit light, the keyboard section 5 can be seen, and the coordinate input section 501 can be supported in accordance with each key position of the keyboard section 5.

Further, the keyboard conversion unit 502 outputs conversion information that matches the keyboard information output from the keyboard unit 5, according to the coordinate information from the coordinate input 81S501. As described above, each key position of the keyboard section 5 and the coordinate position of the coordinate input section 501 are uniquely determined when the lid 2 is closed, and a conversion table can be created in advance. The keyboard conversion section 502 converts the coordinate information into keyboard information according to the conversion table and sends it to the arithmetic processing section 6, so that the arithmetic processing section 6 can convert the input from the keyboard section 6 when the lid 2 is open as shown in FIG. Similarly, key input processing can be performed even when the lid 2 is closed as shown in FIG. In other words, the operator can perform key input regardless of whether the lid 2 is opened or closed.

In this embodiment, as a specific example of the display reversing unit 101, the 10th
As shown in the figure, an example is shown in which the Y electrode driver 111 that drives the Y electrode of the liquid crystal panel 112 is used. Even if the display is electrochromic, it can be realized in the same way as long as it is displayed by sequentially scanning the Y electrode lines described in this embodiment. Furthermore, in order to improve the resolution, the liquid crystal panel described in this embodiment is often driven by dividing it into two screens, an upper and a lower one.In this case, the LCD panel described in this embodiment is Furthermore, it is clear that the object of the present invention can be achieved by providing a downward inversion display function.

Further, in this embodiment, the light scattering plate 103 is provided to improve the visibility of the screen when the lid is closed. For example, the light scattering plate 103
The object of the present invention can be achieved by applying a light-scattering color or coating to the upper part of the main body at the position.

Furthermore, similar to the purpose of the light scattering plate 103, each key of the keyboard section 5 described in this embodiment is made of a color that scatters light, for example, white, so that the visibility of the screen can be further improved.

Next, another specific example of the display reversing unit 101 described in this embodiment will be described.

FIG. 15 is a block diagram centered on the display controller 117 described in FIG. 8. The display data from the arithmetic processing unit 6 is written to a desired position in the display memory 118 according to the address of the display memory 118 set in advance in the write address 603 in the display controller. The address selector 605 switches between a write address and a display address 614, which will be explained below. When displaying, based on the basic clock 609 generated by the timing generation unit 606, the The address 612 and the adder 604 add the display address 614 to the display memory 118 through the address selector 605, read out the display data sequentially, and output the display signal 113 by adjusting the timing and data width in the output control unit 607. Send. In addition, the timing generation unit generates the display latch clock 114 from the basic clock 609, the line latch clock 115 from the X direction carry signal 610,
The first line signal 116 is generated from the Y direction carry signal 608.

FIG. 16 shows an address map of the display memory 118 corresponding to the display panel 1, and in this example, 80 addresses in the X direction and 10 addresses in the Y direction will be explained. As shown in the figure, addresses are an arithmetic series in both the X and Y directions, and therefore addresses can be generated by counters in each direction.

Here, details of address generation will be further explained using the timing chart of FIG. 17. The Y direction carry signal 608 in FIG. 17 causes the X direction address 611. Y
Direction address 612 is initially set. The X direction address 611 is from O to 79 at the falling edge of the basic clock 609.
Count operation is performed until The maximum value of the X direction address is 79.
At the same time, the X direction carry signal 610 is output, and the Y direction address 612 performs a counting operation at the falling edge of the X direction carry signal 610. In this example, the sequence of numbers is 0, 80, 160, 240, 320°..., 640
,720. The display address 614 is the sum of the X-direction address 611 and the Y-direction address 612, and as shown in the figure, it is generated sequentially from O to 799 in synchronization with the basic clock 609. By this operation, the display data specified by the address can be displayed on the display unit 1 at the same position as the address position of the display memory 118 shown in FIG.

As shown in FIG. 15, the lid opening/closing detection section 201 acts on the Y-direction address counter to realize the display reversing section 101. That is, to perform upper and lower inverted display, as explained with reference to FIG. 16, it is only necessary to reverse the address generation order in the Y direction. Therefore, as shown in FIG. 18, the Y direction address 612 is set to 720, 640, 560, 480, .・
・80. Generate a sequence of O, and the other X direction is the 17th

According to this embodiment, a top/bottom reversal display function is added to the light transmission type display panel, and this function is switched by opening and closing the lid on which the display panel is installed, so that the displayed content can be confirmed regardless of whether the lid is opened or closed. In addition, by adding a semi-transparent panel to the display panel, the visibility of the display panel can be increased by switching the light transmission/light reflection by opening and closing the lid, similar to the top and bottom reversal functions. By adding a transparent coordinate recognition device to the display panel, keyboard input can be performed even when the lid is closed.

Specifically, FIG. 19 shows an application example of this embodiment.

This will be explained using FIG. 20. FIG. 19 is a block diagram of the small information processing device shown in FIG.
10 is added, and the role of the switch section is to prohibit the control of the semi-transparent panel 102 by the lid opening/closing detection section 201,
This allows you to control the panel independently. The display section 1 of this embodiment uses a light transmission type display panel. Therefore, as shown in FIG. 20, the lid 2 of the small information processing device
By placing the image on an over-the-air projector (OHP) 9, the display content on the display unit 1 can be enlarged and projected. However, since this device is provided with a function to turn the semi-transparent panel into a light reflecting state when the lid 2 is opened, this embodiment also includes a switch section between the lid opening/closing detection section 201 and the semi-transmissive panel 3.02. 210 is installed on the 0HP9 for projection display, the control of the lid opening/closing detection section 201 is prohibited, and the light transmission/reflection of the semi-transparent panel 102 can be freely controlled. The light transmitting state is essential for the enlarged projection of the 0HP9, and the light reflecting state also takes advantage of the decrease in light transmittance, and as a result turns the projected image of the OHP9 ON/○FF while obstructing the visibility of the display unit 1. There can be no.

By providing the switch section on the semi-transparent panel of this embodiment, a small information processing device can be mounted on an OHP as is, so it can also be used as a presentation device with an integrated keyboard, which improves operability. It is possible to improve transportability, etc.

Next, other embodiments will be described using FIGS. 21 and 22. FIG. 21 is a block diagram of the compact information processing device according to this embodiment, which includes a keyboard section 5.degree. arithmetic processing section 6. The lid opening/closing detection section 201 has the same reference numerals and the same functions as described in the embodiment, and detailed description thereof will be omitted here. The display section 1' and the display section 1'' are light reflective display panels, unlike the embodiment.The switch section 212 and the switch section 213 independently control the display on the display section 1' and the display section 1'', respectively. N/
○It can be used as FF. The selector 211 is the display]
This is to switch whether the display is performed directly from the arithmetic processing section 6 (normal rotation display) or through the display reversal section 191.

FIG. 22 shows a perspective view of a small information processing device to which this embodiment is applied, and the lid 2 has a built-in display section 1' on the inside and a display section 1'' on the outside. The lid opening/closing detection means 201 that detects the open/closed state controls the selector 211 and the switch section 212. That is, when the lid 2 is in the closed state,
The display section 1' is hidden, and only the display section 1'' can be seen from the outside.The lid opening/closing detection section 201 detects the closed state of the lid 2 and prohibits the switch section 212 from displaying information on the display section 1'. The selector 211 sends display data that does not pass through the display reversing section 191 to the display section 1'', and the display section 1'' performs normal rotation display when the keyboard section 5 is brought to the front. Further, when the lid 2 is in an open state, the display section 1' appears with the key fod section 5 in front. Therefore,
The lid opening/closing detection section 201 that has detected the open state of the lid 2 acts on the switch section 212 to permit display on the display section 1'. Since the display section 1'' is hidden in this case, it is generally considered that the lid opening/closing detection means should act on the switch section 213 to prohibit display.However, the display section 1'' is hidden from the keyboard 5 side. However, the entire area can be seen from the opposite position. Therefore, the display reversing section 191 is used to perform upward, downward, left, and right reversal operations so that the display contents can be confirmed in normal rotation even when the lid 2 is open. The lid open/close detector 201 acts on the selector 211,
When the lid 2 is in the open state, display data through the display reversing section 191 is selected. The switch section 213 is provided to inhibit display when the display section 1'' is not required even when the lid 2 is open, and can be controlled by software or hardware.

A specific example of the display reversing unit 191 may be the same as the first embodiment in the upper and lower directions. Further, the left and right directions can also be realized by introducing a similar concept.

According to this embodiment, by arranging the display sections on both sides of the lid of a small information processing device, the displayed contents can be checked regardless of whether the lid is opened or closed, and the switch section is installed to reduce power consumption and maintain confidentiality. The display section, located on the outside of the lid, is equipped with vertical and horizontal reversal display functions, so that the contents displayed on the display section can be viewed in the normal direction regardless of whether the lid is open or closed.

Next, still another embodiment will be described using FIG. 23 and FIG. 24. In this embodiment, by opening and closing the lid while sliding it relative to the main body, it is possible to check the displayed contents using only the only display section built into the lid, whether the lid is opened or closed. FIG. 23 is a perspective view showing the movement of the lid from the open state to the closed state; FIG. 23(a) shows the lid 2 in the closed state, and FIG. 23(d) shows the lid 2 in the open state. . As shown in the figure, the lid 2 slides with respect to the main body 4, and as a result, the display section 1 built into the lid 2 shows a display surface regardless of whether the lid 2 is opened or closed. FIG. 24 shows a specific example of the M2 slide mechanism, in which auxiliary plates 251 and 252 are provided on the side surface of the lid 2, grooves 253 and 254 are provided on the side surface of the main body 4, and auxiliary plates 251 and 252 are provided on the side surface of the main body 4.
Rollers 255°256 are provided at the ends, and auxiliary plates 251, 252
moves together with M2, and rollers 255 and 256 move in groove 2.
By sliding through 53 degrees 254, the lid 2 moves to the position indicated by the broken line in the figure. Note that the auxiliary plates, rollers, and grooves may also be provided on the opposing sides in FIG. 24.

In this way, according to this embodiment, by providing the lid with a sliding mechanism with respect to the main body, it is possible to check the displayed content on the only display section whether the lid 2 is in the open or closed state.

〔Effect of the invention〕

According to the present invention, the display section built into the lid of a small information processing device is of a light-transmitting type, and the display is turned up and down by the lid opening/closing detection means and means.
