[0450] These components cannot be clearly separated, and one component may also serve as another component. For example, a touch panel with a touch sensor overlaid on a functional panel may include a part of the , which is both a display unit and an input unit.

[0451] <<Configuration Example 2 of the Calculation Device 210>> The arithmetic device 210 includes an artificial intelligence unit 213 (see FIG. 17(A)).

[0452] The artificial intelligence unit 213 is supplied with input information II or detection information DS. Based on the force information II or the detection information DS, the control information CI is inferred. 213 provides control information CI.

[0460] The clock signal or timing signal supplied to the control unit 238 included in the display unit 230 or the like can be used as the control information CI. A clock signal or timing signal corresponding to the clock signal can be used as the control information CI.

[0461] <Configuration example 2 of information processing device> Another configuration of a data processing device of one embodiment of the present invention is shown in FIGS. 18A and 18B. The explanation will be given with reference to the above.

[0462] "program" A program according to one embodiment of the present invention includes the following steps (see FIG. 18(A)).

[0463] [First Step] In the first step, the settings are initialized (see FIG. 18(A)(S1)).

[0464] For example, predetermined image information to be displayed at startup and a predetermined mode in which the image information is displayed; and information specifying a predetermined display method for displaying the image information, from the storage unit 212. Specifically, one still image or other moving image information can be used as the predetermined image information. Also, the first mode or the second mode can be used for a predetermined mode.

[0465] [Second step] In the second step, interrupt processing is permitted (see FIG. 18(A)(S2)). The processor that is allowed to process the interrupt can process the interrupt in parallel with the main processing. The processing unit that returns to the main processing from the interrupt processing can This can be reflected in the main processing.

[0466] When the counter value is the initial value, the arithmetic unit is caused to perform an interrupt process. When returning from the program, the counter may be set to a value other than the initial value. After starting up, you can always have the interrupt process run.

[0467] [Third Step] In the third step, the predetermined The image information is displayed using the mode or a predetermined display method (see FIG. 18(A)(S3)). The predetermined mode specifies the mode in which image information is displayed, and the predetermined display method specifies the image information. Also, for example, image information VI can be used to display information. can be done.

[0468] For example, one way of displaying the image information VI can be associated with a first mode. Alternatively, other ways of displaying the image information VI can be associated with the second mode. This allows the display method to be selected based on the selected mode.

[0469] First Mode Specifically, a selection signal is applied to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more. The method of providing the display based on the selection signal can be associated with the first mode.

[0470] For example, if a selection signal is supplied at a frequency of 30 Hz or more, preferably 60 Hz or more, a moving image The movement can be displayed smoothly.

[0471] For example, if the image is updated at a frequency of 30 Hz or more, preferably 60 Hz or more, the user's operation The image that changes smoothly in accordance with the user's operation is displayed on the information processing device 200 that the user is operating. It can be shown.

[0472] Second Mode Specifically, the frequency is less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute. The method of supplying a selection signal to one scanning line at a time and displaying based on the selection signal is called the second mode. It can be associated with a

[0473] A selection signal at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute By supplying the above, it is possible to display a picture with reduced flicker or flicker. Power consumption can be reduced.

[0474] For example, when the information processing device 200 is used as a clock, the frequency is once per second or once per minute. The display can be updated with frequency, etc.

[0475] Incidentally, when a light-emitting element is used as a display element, the light-emitting element is made to emit light in a pulsed manner. Specifically, the organic EL element emits light in a pulsed manner, and image information can be displayed. The afterglow can be used for display. This may shorten the time for driving the light emitting element and reduce power consumption. In this case, heat generation is suppressed, and therefore deterioration of the light-emitting element can be reduced in some cases.

[0476] [Fourth step] In the fourth step, if a termination command is provided, the process proceeds to the fifth step. If no value is supplied, the process proceeds to the third step (FIG. 18(A)(S4) reference).

[0477] For example, the termination command supplied in the interrupt process may be used for the determination.

[0478] [5th ​​step] In the fifth step, the process ends (see FIG. 18(A)(S5)).

[0479] <<Interrupt Processing>> The interrupt process comprises the following sixth to eighth steps (see FIG. 18(B)). .

[0480] [Sixth step] In the sixth step, for example, the detection unit 250 is used to detect whether the information processing device 200 is being used. The illuminance of the environment is detected (see FIG. 18(B)(S6)). The color temperature and chromaticity of the ambient light may also be detected.

[0481] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (FIG. 18(B) ) (See S7)). For example, the brightness of the display should not be too dark or too bright. is decided.

[0482] If the color temperature or chromaticity of the ambient light is detected in the sixth step, the display The color may be adjusted.

[0483] [Eighth Step] In the eighth step, the interrupt process ends (see FIG. 18(B) (S8)).

[0484] <Configuration example 3 of information processing device> Another configuration of a data processing device of one embodiment of the present invention will be described with reference to FIG.

[0485] FIG. 19A is a flowchart illustrating a program according to one embodiment of the present invention. (A) is a flowchart illustrating an interrupt process different from the interrupt process shown in FIG. 18(B). It is a chart.

[0486] The information processing device of the third example configuration changes the mode based on a given event. The fact that the interrupt process includes a step for This section will explain the differences in detail and explain how to use a similar configuration. The above explanation will be used for the parts that can be described.

[0487] Interrupt handling The interrupt process comprises the following steps 6 to 8 (see FIG. 19(A)). .

[0488] [Sixth step] In the sixth step, if a predetermined event is provided, the process proceeds to the seventh step; If the predetermined event is not provided, proceed to the eighth step (FIG. 19(A) (U6 For example, you can use the condition whether a specific event was provided within a specific period. Specifically, it is possible to perform the above-mentioned operation for 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less. The predetermined period may be a period longer than 0 seconds.

[0489] [Seventh step] In the seventh step, the mode is changed (see FIG. 19(A)(U7)). Specifically, If you have selected the first mode, select the second mode, and then select the second mode. If so, select the first mode.

[0490] For example, the display mode can be changed for a part of the area of ​​the display unit 230. Specifically, the display unit 230 includes the drive circuits GDA, GDB, and GDC. The display mode can be changed for the area to which one drive circuit supplies a selection signal ( See Figure 19(B)).

[0491] For example, the input section 240 in the area overlapping the area where the driver circuit GDB supplies the selection signal is When a specific event is supplied, the driver circuit GDB supplies a selection signal to the display model of the area. The code can be changed (see Figure 19(B) and Figure 19(C)). The driver circuit GDB supplies a "tap" event to the touch panel using The frequency of the selection signal can be changed.

[0492] The signal GCLK is a clock signal that controls the operation of the driver circuit GDB, and the signal PWC Signals PWC1 and PWC2 are pulse width control signals that control the operation of the driver circuit GDB. The circuit GDB outputs a selection signal based on the signal GCLK, the signal PWC1, the signal PWC2, etc. is supplied to the conductive films G2(m+1) to G2(2m).

[0493] This allows, for example, the driver circuits GDA and GDC to supply a selection signal. Alternatively, the driver circuit GDB can provide the selection signal. The driver circuit GDB selects the area without changing the display of the area to which the driver circuit GDC supplies the selection signal. The display of the area to which the select signal is supplied can be updated. can be suppressed.

[0494] [Eighth Step] In the eighth step, the interrupt process is completed (see FIG. 19(A)(U8)). The interrupt process may be repeatedly executed during the period when the main process is being executed.

[0495] 《Specified Events》 For example, "click" and "drag" operations are performed using a pointing device such as a mouse. Events such as "tap" and "drag" are supplied to the touch panel using a finger as a pointer. Events such as "click" or "swipe" can be used.

[0496] Also, for example, the position of the slide bar pointed by the pointer, the speed of the swipe, the speed of the drag, The degree or the like can be used to provide arguments for the command associated with a given event.

[0497] For example, the information detected by the detection unit 250 is compared with a preset threshold value, and the comparison result is can be used for events.

[0498] Specifically, a pressure-sensitive detector that comes into contact with a button or the like that is arranged so that it can be pressed into the housing. etc. can be used in the detection unit 250.

[0499] Commands associated with specific events For example, the termination command may be associated with a predetermined event.

[0500] For example, the "page turning" function is used to switch the display from one image information to another. The "page turn command" can be associated with a specific event. The arguments that determine the page turning speed, etc., used when executing are passed using a specified event. can be given.

[0501] For example, the display position of a part of one image information is moved to display a part of the image information that is continuous with the part. You can associate a "scroll command" to display other parts with a specified event. In addition, the speed at which the display position is moved when a "scroll command" is executed is determined by The arguments to be used can be given using a given event.

[0502] For example, a command to set a display method or a command to generate image information is generated as a predetermined event. It is possible to associate the argument that determines the brightness of the generated image with a specific event. In addition, the argument that determines the brightness of the generated image can be associated with the The determination may be based on the brightness of the environment detected by the 50 .

[0503] For example, information distributed using a push-type service is acquired using the communication unit 290. An instruction to execute a command can be associated with a given event.

[0504] The qualification to obtain information is determined using the location information detected by the detection unit 250. Specifically, a person who is in a designated classroom, school, conference room, company, building, or other area may This may allow a school or The information processing device 200 can be used as a textbook or the like by receiving teaching materials distributed in classrooms at universities, etc. (See Figure 17(C)). Or, you can receive materials distributed in a conference room of a company, etc. , and can be used for conference materials.

[0505] <Configuration example 4 of information processing device> Another configuration of a data processing device of one embodiment of the present invention will be described with reference to FIG.

[0506] FIG. 20A is a flowchart illustrating a program according to one embodiment of the present invention. (A) is a flowchart illustrating an interrupt process different from the interrupt process shown in FIG. 18(B). FIG. 20(B) is a schematic diagram explaining the operation of the program shown in FIG. 20(A). FIG. 20(C) is a schematic diagram of the photographed fingerprint.

[0507] The fourth example of the configuration of the information processing device described with reference to FIG. 20A is the same as the fourth example of the configuration of FIG. The configuration example described with reference to the present embodiment differs in the interrupt processing. Based on the events, a step of identifying the area, a step of generating an image, and a step of displaying the image The interrupt process includes a step of capturing an image and a step of taking an image. The above description will be used in the case where a similar configuration can be used. .

[0508] Interrupt handling The interrupt process comprises the sixth to eleventh steps (see FIG. 20(A)).

[0509] [Sixth step] In the sixth step, if a predetermined event is provided, the process proceeds to the seventh step; If the predetermined event is not provided, proceed to step 11 (FIG. 20(A)(V See 6).

[0510] For example, the detector 250 can be used to provide a predetermined event. A movement such as lifting an information processing device can be used as a predetermined event. The acceleration sensor or acceleration sensor can be used to detect the movement of the information processing device. Alternatively, a touch sensor can be used to detect contact or proximity of a subject such as a finger. Cut.

[0511] [Seventh step] In the seventh step, the first region SH is identified (see FIG. 20(A)(V7)).

[0512] For example, when a subject such as a finger touches or approaches the input / output device 220 according to one embodiment of the present invention, The area can be set as the first area SH. Alternatively, the area can be set as the area previously set by the user. can be used for the first region SH.

[0513] Specifically, a finger THM or the like that comes into contact with or is close to the functional panel according to one embodiment of the present invention is detected by a pixel 7. 03(i,j) and then perform image processing to identify the first region SH. (See FIG. 20(B)).

[0514] For example, the shadows created by the contact or proximity of a subject such as a finger (THM) blocking external light can be captured by this camera. The pixel 703(i, j) of the functional panel according to one embodiment of the present invention is used to take an image, and the image is processed. 1 can be identified.

[0515] Alternatively, the pixel 703(i,j) of the functional panel according to one embodiment of the present invention may be used to detect contact or proximity. The object, such as a finger THM, is illuminated with light, and the light reflected by the object is reflected by the pixel 703(i, j) and then processing the image to identify the first region SH.

[0516] Alternatively, a touch sensor may be used to set the area touched by a subject such as a finger THM as the first area SH. It can be identified.

[0517] [Eighth Step] In the eighth step, a second region and a third region are generated based on the first region SH. An image FI including the image is generated (see Fig. 20(A)(V8) and Fig. 20(B)). For example, The shape of the region SH is used as the shape of the second region, and the region excluding the first region SH is used as the shape of the third region. Used for.

[0518] [9th step] In a ninth step, the image FI is displayed so that the second region overlaps the first region SH. (See Figure 20(A)(V9) and Figure 20(B)).

[0519] For example, an image signal is generated from an image FI and supplied to the region 231, and a pixel 703(i,j) Alternatively, during the period when the first selection signal is supplied to the conductive film G1(i), The generated image signal is supplied to the conductive film S1g(j), and the image signal is written to the pixel 703(i,j). Alternatively, the generated image signal can be input to the conductive film S1g(j) and the conductive film S2g (j), and the enhanced image signal can be written to pixel 703(i,j). Alternatively, the enhanced image signal can be used to display an image with increased brightness.

[0520] As a result, the area 231 touched by the subject such as a finger or the like is overlapped with the first area SH adjacent thereto. Alternatively, the image FI can be displayed by adding pixels 70 to the area touched by the subject such as a finger. 3(i,j) can be used to illuminate the object. Alternatively, the touching or nearby finger THM Or, you can set the area in advance by the user. The user can be prompted to touch or bring a subject such as a finger close to the object.

[0521] [Step 10] In a tenth step, while the image FI is being displayed, the first area SH is touched or brought into proximity. The subject is imaged (see FIG. 20(A)(V10) and FIG. 20(B)).

[0522] For example, a finger THM or the like located near the area 231 is photographed while being irradiated with light. Specifically, the fingerprint FP of the finger THM in contact with the area 231 can be photographed (see FIG. 20). (See (C)).

[0523] For example, when an image is displayed on pixel 703(i,j), the supply of the first selection signal is stopped. For example, the supply of the first selection signal to the pixel circuit 530G(i,j) can be In a stationary state, image capture can be performed using pixel 703(i,j).

[0524] This allows a subject, such as a finger, that is in contact with or in close proximity to the object to be photographed while being illuminated. Alternatively, an image can be captured during a period when the first selection signal is not being supplied. It is possible to suppress noise during imaging, or obtain a clear image of the fingerprint. Or, an image can be obtained that can be used to authenticate the user. The fingerprint of a finger touching the area 231 can be clearly photographed anywhere in the area 231. As a result, a novel information processing device with excellent convenience and reliability can be provided. do.

[0525] [Step 11] In the eleventh step, the interrupt process ends (see FIG. 20(A)(V11)).

[0561] In addition, the circuit diagram shows independent components as if they are electrically connected to each other. Even if the components are different, one component may have the functions of multiple components. For example, when a part of the wiring also functions as an electrode, one conductive film functions as both the wiring and the electrode. Therefore, the electrode in this specification has the functions of both components. The term "electromagnetic connection" refers to a case where one conductive film has the functions of multiple components. This also falls within the scope of the above. [Explanation of symbols]
