Description

The invention described in this specification relates to a power saving technique of a portable self-luminous display device.
The invention proposed by the inventors has aspects as a self-luminous display device, a battery-driven device, and an image data generation method.

  Electronic devices (battery-driven devices) driven by a battery power source are required to further reduce power consumption. In particular, in the case of an electronic device equipped with a display screen, lower power consumption of the power consumed on the display screen is further demanded.

In view of this, it has been proposed to install a function (partial display function) for displaying an image on only a part of a display screen in conjunction with a usage scene and display contents in some mobile phones.
Patent documents disclosing such a partial display function are shown below.

JP 2002-351414 A JP 2001-356746 A In these patent documents, there is a technique for reducing power consumption by selecting display or non-display of an arbitrary block in units of blocks divided for each of a plurality of scanning lines. It is disclosed.

In this patent document, there is a technique in which a system control unit sets a display area and a non-display area according to display contents and the like, and displays an image only on a part of the display screen based on the setting. It is disclosed.

  However, these partial display functions are intended to reduce power consumption during periods when the user does not use them. For example, it is intended to leave only a clock display and a battery remaining amount display on a part of the display screen.

Thus, with the currently proposed technology, there is no mechanism in which a user who is using a battery-powered device is actively or actively involved in the partial display function.
Actually, the partial display area is determined by the system control unit in accordance with the display contents. That is, the partial display function cannot be realized without the involvement of the system control unit.

  Therefore, the inventors propose a power saving technique that can limit the display area of the original image to a part of the screen without involvement of the system control unit.

(A) Solution 1
First, as one solution, the inventors propose a self-luminous display device having the following mechanism.
(A) Light emitting area in which a self-luminous display element is arranged (b) A movable mechanism that can be arbitrarily moved by the user (c) Partial area setting for setting an arbitrary partial area on the light emitting area based on operation information for the movable mechanism (D) An image data selection unit that supplies original image data as it is to a partial area and supplies black data to areas other than the partial area

(B) Solution 2
As another solution, the inventors propose a self-luminous display device having the following mechanism.
(A) Light emitting area in which a self-luminous display element is arranged (b) A movable mechanism that can be arbitrarily moved by the user (c) Partial area setting for setting an arbitrary partial area on the light emitting area based on operation information for the movable mechanism Part (d) Luminance reduction part for reducing the emission luminance value of the original image data (e) The original image data is supplied as it is to the partial area, and the image data given from the luminance reduction part is supplied to the area other than the partial area Image data selection section

(C) Solution 3
As another solution, the inventors propose a self-luminous display device having the following mechanism.
(A) Light emitting area in which a self-luminous display element is arranged (b) A movable mechanism that can be arbitrarily moved by the user (c) Partial area setting for setting an arbitrary partial area on the light emitting area based on operation information for the movable mechanism Part (d) an average picture level calculation part for calculating an average picture level of original image data corresponding to an area other than the set partial area (e) replacement image data having an average picture level smaller than the calculated average picture level (F) An image data selection unit that supplies original image data as it is to a partial area and supplies the replacement data to areas other than the partial area

  By using the power saving technology proposed by the inventors, the user can arbitrarily move the movable mechanism, and the partial area of any size on the display screen without any involvement of the system control unit. Can be set.

  The area other than the set partial area is replaced with an image that consumes less power than the original image (for example, black data and image data with reduced emission luminance). As a result, the user can be actively or actively involved in power saving.

Hereinafter, the power saving technique according to the invention will be described.
In addition, the well-known or well-known technique of the said technical field is applied to the part which is not specifically illustrated or described in this specification.
Moreover, the form example demonstrated below is one form example of invention, Comprising: It is not limited to these.

(A) Form example 1
(A-1) Appearance Configuration FIG. 1 shows an example of the appearance configuration of the display device 1 that operates by receiving drive power from a battery power supply. On the surface of the housing 3 constituting the display device 1 shown in FIG. 1, an information display unit 5 and a lid 7 that is freely movable along the surface are arranged.

  The information display unit 5 is a display area that can display an arbitrary image or video. In the case of this embodiment, the information display unit 5 is composed of an organic EL display panel. Note that the organic EL display panel used in this embodiment is capable of color display. That is, one pixel on the display is composed of sub-pixels corresponding to R (red), G (green), and B (blue).

  The lid 7 is a cylindrical movable member that is slightly larger than the outer shape of the housing 3. The lid 7 is attached to the housing 3 so as to be freely movable in the direction indicated by the arrow in the figure. In the case of this embodiment, the lid 7 is formed of a member that is impermeable or has low permeability. That is, the lid 7 is configured to hide the display content of the information display unit 5 from the outside.

  Therefore, the opening / closing operation of the lid 7 is executed not only for the purpose of protecting the surface of the information display unit 5 but also for the purpose of hiding a part of the display content. In other words, the lid 7 is opened and closed for the purpose of dividing it into a partial area where the original image is observed as it is from the outside and another partial area where the original image cannot be observed at all, or even if the original image cannot be expected. used.

  FIG. 2 shows a partial region set by opening / closing the lid 7. In this specification, a partial area that is not hidden by the lid 7 in the information display unit 5 is referred to as an original image area 11. In the original image area 11, the original image is displayed as it is with the original image quality. Further, a portion hidden in the information display unit 5 by the lid 7 is referred to as a power saving region 13. In the power saving area 13, an image with lower power consumption than the original image displayed at the same position is displayed.

The image displayed in the power saving area 13 may be a fixed image set in advance (for example, a full black image) or an image generated according to the display content of the original image.
In any case, the setting of the original image area 11 is realized by a manual operation of the lid 7 by the user, and is independent of the display content. That is, the partial area can be set without involvement of the system control unit.

(A-2) Functional Configuration of Display Device FIG. 3 shows a functional configuration example of devices constituting the display device 1. Note that FIG. 3 illustrates some of the functions mounted on the display device 1 in order to explain the functional configuration of the device related to the setting of the partial area by the operation of the lid 7 and the generation of the image data linked to this. Abbreviated. For example, functional blocks related to signal processing of original image data, a system control unit that controls the operation of the entire system, and the like are omitted.

  In the functional configuration shown in FIG. 3, the display device 1 includes a timing controller 21, a partial area setting user interface (UI) 23, a display area decoder 25, a partial area setting unit 27, an image data selection unit 29, and a black data supply unit 31. , A gate scan driver 33, a line sequential driver 35, and an organic EL display panel 37.

  The timing controller 21 is a control device that generates a control signal necessary for screen display based on the original image data Dp. For example, a dot clock, H sync, and V sync are generated. The dot clock is a signal corresponding to the reciprocal of the time required for displaying one pixel (dot). The H sync is a horizontal synchronization signal that gives the head position of the scanning line. V sync is a vertical synchronization signal that gives the start position of a frame.

  Among these, the H sink is output to the gate scan driver 33. The timing controller 21 also performs an operation of converting the output timing of the original image data Dp into a timing that matches the panel specifications. The original image data Dp after the timing conversion is output to the subsequent image data selection unit 29.

  The partial area setting user interface (UI) 23 is a movable mechanism that is manually operated by the user. In the case of this example. It comprises a lid 7 (FIG. 1) and an internal mechanism that detects its movable position.

  FIG. 4 shows a configuration example of the partial area setting user interface (UI) 23. As shown in FIG. 4, the partial area setting user interface (UI) 23 includes a lid 7, a contact terminal 41, a resistor 43, and an analog / digital converter 45.

  The contact terminal 41 and the resistor 43 function as a variable resistor. The contact terminal 41 is fixed to the lid 7. Therefore, the contact position between the contact terminal 41 and the resistor 43 changes as the lid 7 is moved. On the other hand, a certain voltage is applied to both ends of the resistor 43. Therefore, an analog voltage corresponding to the resistance value between the contact terminal 41 and the ground electrode is generated.

The length of the resistor 43 and the value of the constant voltage are set so that the boundary position P of the screen area hidden by the movable operation of the lid 7 can be identified.
The analog / digital converter 45 converts the analog voltage supplied from the contact terminal 41 into a digital value. This digital value represents the vertical end position of the original image area 11.

The display area decoder 25 is a processing device that converts a digital value given from the analog / digital converter 45 into pixel number information of the display panel. The number of pixels is given based on the total number of pixels of the display panel. The information display unit 5 described above corresponds to an effective display area where the user can actually confirm an image or video.
In the case of this embodiment, the display area decoder 25 converts the pixel number (scanning line) from the top in the vertical direction to information indicating the original picture area 11 from the pixel (scanning line).

  In the case of this embodiment, the number of pixels (operation lines) giving the start position of the original image area 11 is fixed, and only the number of pixels (operation lines) giving the end position is variably given. Here, the display area decoder 25 outputs the start position and the end position of the original image area 11 as the count value of the H sync counter.

The count value of the H sync counter is reset to “0 (zero)” at the start edge of V sync. Therefore, in the case of FIG. 4, the count value corresponding to the start position of the original image area 11 is “3”, and the count value corresponding to the end position of the original image area 11 is “8”.
By the way, in the case of this embodiment, the lid 7 cannot be moved in the horizontal direction. Therefore, preset values are output as the count value for giving the start position and the end value for giving the end position of the original image area 11.

  The count value that gives the position in the horizontal direction is given as the count value of the clock counter that starts counting the dot clock at the edge of H sync. For example, the count value corresponding to the start position of the original image area 11 is “3”, and the count value corresponding to the end position of the original image area 11 is “15”.

  The partial area setting unit 27 is a processing device that sets the determination condition of the original image area 11 and the determination condition of the power saving area 13 based on the count value given from the display area decoder 25. FIG. 5 shows an image of setting determination conditions.

  In the case of FIG. 5, the horizontal pixel range that provides the original image area 11 is set such that the clock count value H is not less than a and not more than b. The vertical pixel range that provides the original image area 11 is set such that the H sync count value V is not less than c and not more than d.

  On the other hand, the vertical pixel range providing the original image area 11 is set as a range where the clock count value H is 0 or more and less than a and a range which is greater than b and less than the clock maximum value α. The vertical pixel range for providing the original image area 11 is set as a range where the H sync count value V is 0 or more and less than c, and a range greater than d and less than the clock maximum value β.

  The image data selection unit 29 determines which of the two display areas given by the partial area setting unit 27 each pixel of the original image data Dp given from the timing controller 21 belongs to, and based on the judgment result, the line sequential driver 35 is a processing device that generates display image data to be output to 35.

  In the case of this embodiment, the image data selection unit 29 outputs the original image data Dp in the original image area 11 and outputs the black data Db in the power saving area 13. The black data Db means a gradation value “0 (zero)”. The black data Db is given from the black data supply unit 31.

FIG. 6 shows an internal configuration example of the image data selection unit 29. The image data selection unit 29 includes a switching control unit 51 and a switching unit 53.
The switching control unit 51 compares the H sync count value and the clock count value given from the timing controller 21 with the determination condition, and the pixel to be determined is located in the original image area 11 or in the power saving area 13. It is determined whether or not.

  The determination result of the switching control unit 51 is used as a switching signal for the switching unit 53. The switching unit 53 outputs either the original image data Dp or the black data Db to the line sequential driver 35 based on the switching signal.

The gate scan driver 33 is a drive circuit that outputs a line selection signal (H sink) to the organic EL display panel 37.
The line sequential driver 35 is a drive circuit that converts a digital value of display image data into an analog value for each line and outputs the converted analog value to the organic EL display panel 37.

  The organic EL display panel 37 is a display device in which an organic EL element is disposed at a position corresponding to each pixel (subpixel). Each pixel (subpixel) is controlled by a respective pixel circuit. That is, each pixel (subpixel) is controlled by a line selection signal for selecting a pixel circuit and an analog value for controlling the light emission amount. In the case of this embodiment, the power saving area 13 is a black screen.

(A-3) Change of display screen by operation of lid FIG. 7 shows an example of a display screen of the display device 1 equipped with the display technology described above.
FIG. 7A shows the relationship between a usage example (left in the figure) when the lower part of the information display unit 5 is slightly hidden by the lid 7 and an actual display screen example (right in the figure). As shown in the figure, only a small part (power saving area 13) hidden by the lid 7 becomes a black screen.

  FIG. 7B shows a relationship between a usage example (left in the figure) when the lower half of the information display unit 5 is hidden by the lid 7 and an actual display screen example (right in the figure). As shown in the figure, the lower half (power saving area 13) of the screen hidden by the lid 7 is a black screen.

  FIG. 7C shows a relationship between a usage example (left in the figure) and an actual display screen example (right in the figure) when substantially the entire surface of the information display unit 5 is hidden by the lid 7. As shown in the figure, almost all the screen (power saving area 13) hidden by the lid 7 becomes a black screen.

  As described above, the area where the original image is displayed as it is is determined independently of the display content of the original image (regardless of the system control unit) and only depending on the operation position of the lid 7 that is movable by the user. That is, even during the display of the screen, it is possible to display only the screen area that the user has positively or actively determined, and to switch the other screen areas to the black screen display.

Since the organic EL element is a self-luminous element, no drive current flows through the organic EL element located in the black screen region.
For this reason, current consumption in the black screen region can be eliminated. That is, power consumption can be greatly reduced. As a result, the time during which the display device 1 can be driven by a battery power source can be lengthened.

(B) Embodiment 2
(B-1) Appearance Configuration FIG. 8 shows an example of the appearance configuration of the display device 101 that operates by receiving drive power from a battery power supply. In FIG. 8, parts corresponding to those in FIG.
On the surface of the housing 3 constituting the display device 101 shown in FIG. 8, an information display unit 5, a lid 7 that is freely movable along the surface, and a visible light sensor 103 that detects a movable position of the lid 7 are provided. Deploy. The visible light sensor 103 is composed of, for example, a photodiode.

A mechanism specific to the display device 101 shown in FIG. 8 is a plurality of visible light sensors 103 arranged along the movable direction of the lid 7.
FIG. 9 shows the positional relationship between the arrangement position of the visible light sensor 103 and the lid 7. As shown in FIG. 9, the visible light sensor 103 is arranged along the vertical direction (vertical scanning direction) of the information display unit 5.

Here, at least one visible light sensor 103 is disposed outside the movable range of the lid 7. The visible light sensors 103 are arranged at intervals corresponding to the count value of the H sync counter. However, the installation interval varies depending on the size of the visible light sensor 103.
In the case of FIG. 9, one visible light sensor 103 is arranged outside the upper end position of the information display unit 5 that is the upper limit position of the movable range of the lid 7.

  Thus, the reason why one visible light sensor 103 is arranged outside the movable range is to make it possible to determine the brightness of the usage environment of the display device 101. When such a visible light sensor 103 is not provided, for example, all visible light sensors 103 do not detect light because the cover 7 covers the entire area of the information display unit 5, or all visible light is used because the use environment is dark. This is because it cannot be determined whether the sensor 103 does not detect light.

(B-2) Functional Configuration of Display Device FIG. 10 shows a functional configuration example of devices that constitute the display device 101. In FIG. 10, parts corresponding to those in FIG. 3 are denoted by the same reference numerals.
The display device 101 includes a timing controller 21, a partial area setting user interface (UI) 111, a display area decoder 113, a partial area setting section 27, an image data selection section 29, a black data supply section 31, a gate scan driver 33, a line The driver 35 and the organic EL display panel 37 are sequentially formed.

That is, except for the partial area setting user interface (UI) 111 and the display area decoder 113, the same ones as in the first embodiment are used.
In the case of this embodiment, the partial area setting user interface (UI) 111 includes the lid 7 and a plurality of visible light sensors 103. The detection result of each visible light sensor 103 is output to the display area decoder 113.

  The display area decoder 113 is a processing device that converts the boundary position between the visible light sensor 103 where light is detected and the visible light sensor 103 where light is not detected into pixel number information of the display panel. Note that the region of the visible light sensor 103 in which light is detected corresponds to the original image region 11, and the region of the visible light sensor 103 in which no light is detected corresponds to the power saving region 13.

  In the case of this embodiment, on the condition that the visible light sensor 103 disposed outside the movable range of the lid 7 receives light, the display area decoder 113 and the visible light sensor 103 and the light detected by the light are detected. It is determined that the boundary position of the visible light sensor 103 in which no is detected is the end position of the original image area 11. In the case of this embodiment as well, the start position of the original image area 11 is fixed.

On the other hand, when all the visible light sensors 103 including the visible light sensor 103 arranged outside the movable range of the lid 7 do not detect light, the display area decoder 113 determines that the lid 7 is not closed. It is determined that the entire screen is the original image area 11.
In any case, the display area decoder 113 outputs the start position and end position of the original image area 11 as the count value of the H sync counter.

(B-3) Change of display screen by operation of lid FIGS. 11 to 14 show examples of display screens of the display device 101 equipped with the display technology described above.
FIG. 11 shows an example of a display screen when the lid 7 is operated so that only one visible light sensor 103 located below the information display unit 5 is hidden. As shown in the figure, only a small part (power saving area 13) hidden by the lid 7 becomes a black screen.

  FIG. 12 shows an example of a display screen when the lid 7 is operated so that only the five visible light sensors 103 located substantially in the lower half of the information display unit 5 are hidden. As shown in the figure, only the lower half (power saving region 13) of the screen hidden by the lid 7 is a black screen.

  FIG. 13 shows an example of a display screen when all visible light sensors 103 within the movable range of the lid 7 are hidden by the lid 7. However, in the case of FIG. 13, it is assumed that the visible light sensor 103 arranged outside the movable range of the lid 7 receives light. In this case, it means that all the lids 7 are closed, so that the entire area of the information display unit 5 becomes a black screen.

  FIG. 14 also shows a display screen example when all the visible light sensors 103 within the movable range of the lid 7 are hidden by the lid 7. However, in the case of FIG. 14, the visible light sensor 103 arranged outside the movable range of the lid 7 is also not receiving light. For example, this corresponds to a case where the display device 101 is used at night when the lighting apparatus is not turned on. In this case, since the lid 7 is not necessarily closed, the entire area of the information display unit 5 is set as the original image area 11, and the original image is displayed under such screen brightness according to the use environment. .

  As described above, even in this embodiment, the region where the original image is displayed as it is is the operation of the lid 7 that the user can move regardless of the display content of the original image (irrespective of the system control unit). It depends only on the position. That is, even during the display of the screen, it is possible to display only the screen area that the user has positively or actively determined, and to switch the other screen areas to the black screen display.

  In addition, since the organic EL element is a self-luminous element, it is possible to prevent a drive current from flowing through the organic EL element located in the black screen region, and power consumption can be significantly reduced. As a result, the time during which the display device 1 can be driven by a battery power source can be lengthened.

  In addition, when using the visible light sensor 103 as in this embodiment, as shown in FIG. 15, if the usage is such that the surface of a part of the visible light sensor 103 is covered with a user's finger or the like. It is also possible to display the black screen only for the region where light is not received so that the contents of the image cannot be observed from the outside.

That is, highly confidential information can be protected from peeping.
However, in order to realize such display, it is necessary to set the display area decoder 113 and the partial area setting unit 27 so that a plurality of original image areas 11 can be set in the information display unit 5.

(C) Embodiment 3
(C-1) Appearance Configuration FIG. 16 shows an example of the appearance configuration of the display device 201 that operates by receiving drive power from a battery power source. In FIG. 16, the same reference numerals are given to portions corresponding to those in FIG. 1.
On the surface of the housing 3 constituting the display device 201 shown in FIG. 16, the information display unit 5 and the original image area setting operators 203, 205, 207, and 209 are arranged.

A mechanism peculiar to the display device 201 shown in FIG. 16 is four operators 203, 205, 207, and 209 arranged on the side surface of the housing 3 for setting the original image area 11. All of these four operators 203, 205, 207, and 209 are movably attached to the housing 3.
FIG. 17 shows a setting example of the original image area 11 and the power saving area 13 by the movable operation of these operators 203, 205, 207, and 209.

Unlike the two embodiments described above, the start position and end position of the original image area 11 can be arbitrarily set not only in the vertical direction but also in the horizontal direction. For this reason, it is possible to set an original image area 11 having an arbitrary size at an arbitrary position on the information display unit 5.
Note that the operator 203 is used to input a start position (upper end position) of the original image area 11 in the vertical direction.

On the other hand, the operator 205 is used to input an end position (lower end position) of the original image area 11 in the vertical direction.
The operation element 207 is used to input a start position (left end position) of the original image area 11 in the horizontal direction.
The operation element 209 is used to instruct and input the end position (right end position) of the original image area 11 in the horizontal direction.

(C-2) Functional Configuration of Display Device FIG. 18 shows a functional configuration example of devices that constitute the display device 201. In FIG. 18, parts corresponding to those in FIG. 3 are denoted by the same reference numerals.

  The display device 201 includes a timing controller 21, a partial area setting user interface (UI) 211, a display area decoder 213, a partial area setting unit 27, an image data selection unit 29, a black data supply unit 31, a gate scan driver 33, a line The driver 35 and the organic EL display panel 37 are sequentially formed.

That is, except for the partial area setting user interface (UI) 211 and the display area decoder 213, the same ones as in the first embodiment are used.
In the case of this embodiment, the partial area setting user interface (UI) 211 is composed of the operators 203, 205, 207, and 209 and an internal mechanism for detecting the movable position thereof.

  19 and 20 show a configuration example of the partial area setting user interface (UI) 211. FIG. Note that the configuration shown in FIG. 19 corresponds to a movable mechanism used for setting the start position and the end position of the original image area 11 in the vertical direction of the information display unit 5. On the other hand, the configuration shown in FIG. 20 corresponds to a movable mechanism used for setting the start position and the end position of the original image area 11 in the horizontal direction of the information display unit 5.

The configurations of these movable mechanisms correspond to the same configurations as the four partial area setting user interfaces (UI) 23 described in the first embodiment.
Therefore, as shown in FIG. 19, the movable mechanism that sets the start position in the vertical direction includes an operation element 203, a contact terminal 221, a resistor 223, and an analog / digital converter 225.

  Similarly, as shown in FIG. 19, the movable mechanism for setting the vertical end position includes an operator 205, a contact terminal 231, a resistor 233, and an analog / digital converter 235. The analog / digital converters 225 and 235 convert analog values corresponding to the operation positions of the operators 203 and 205 into digital values and output them to the display area decoder 213.

Further, as shown in FIG. 20, the movable mechanism for setting the horizontal start position includes an operation element 207, a contact terminal 241, a resistor 243, and an analog / digital converter 245.
Similarly, as shown in FIG. 20, the movable mechanism for setting the horizontal end position includes an operation element 209, a contact terminal 251, a resistor 253, and an analog / digital converter 255.

  Similarly, the analog / digital converters 245 and 255 convert analog values corresponding to the operation positions of the operators 207 and 209 into digital values and output them to the display area decoder 213.

  The display area decoder 213 uses the digital value corresponding to the four edge positions (two points in the vertical direction and two points in the horizontal direction) set by the user's movable operation as pixel number information of the display panel in the corresponding direction. It is a processing device to convert to.

  Also in this case, the pixel number information is given based on the total number of pixels of the display panel. 19 and 20, the vertical pixel position is given in the range of 0 to 11 of the H sync counter, and the horizontal pixel position is given in the range of 0 to 15 of the clock counter.

  However, since the start position and end position of the original image area 11 are given by pixels in the effective display area of the information display unit 5, the vertical pixel position is in the range of 3 to 11, and the horizontal pixel position is 3. To 15 in the range.

In the case of FIGS. 19 and 20, the start position in the vertical direction is given by “3” and the end position is given by “8”. The horizontal start position is given by “4” and the end position is given by “9”.
FIG. 21 shows a setting example of the determination condition output by the partial area setting unit 27. FIG. 21 corresponds to FIG. 5 used in the description of the first form example. The difference between FIG. 21 and FIG. 5 is only the pixel range in the horizontal direction. With this procedure, information that gives the edge position of the original image area 11 is supplied to the partial area setting unit 27.

(C-3) Change of display screen by operation of operation element FIGS. 22 to 24 show examples of display screens of the display device 201 equipped with the display technology described above.
FIG. 22 is a display screen example when the start position and end position of the original image area 11 are set inside the information display section 5 only in the vertical direction. In this case, black screens appear on the upper and lower sides of the information display unit 5, and only the vicinity of the center of the original image is displayed in full size in the horizontal direction.

  FIG. 23 is a display screen example when the start position and end position of the original image area 11 are set inside the information display section 5 only in the horizontal direction. In this case, black screens appear on the left and right sides of the information display unit 5, and only the vicinity of the center of the original image is displayed in full size in the vertical direction.

  FIG. 24 is an example of a display screen when the start position and the end position of the original image area 11 are set inside the information display unit 5 in each of the horizontal direction and the vertical direction. In this case, the original image is displayed only in the central portion of the information display unit 5, and a black screen is displayed around the original image.

  As described above, also in the case of this embodiment, the region where the original image is displayed as it is is the operation element 203 that the user can move regardless of the display content of the original image (irrespective of the system control unit), It is determined depending on only the operation positions 205, 207, and 209.

  That is, even during the display of the screen, it is possible to display only the screen area that the user has positively or actively determined, and to switch the other screen areas to the black screen display. In addition, in the case of this embodiment, the position and size of the original image area 11 can be freely set, so that the user's intention can be further reflected in the screen configuration.

  Of course, since the organic EL element is a self-luminous element, it is possible to prevent the drive current from flowing through the organic EL element located in the black screen region, and the power consumption can be greatly reduced. As a result, the time during which the display device 1 can be driven by a battery power source can be lengthened.

Specifically, a mode example in which a push button type movable mechanism is used instead of the operators 203, 205, 207, and 209 that can be slid in both directions will be described.

FIG. 25 shows an example of the external configuration of a display device 301 that operates by receiving drive power from a battery power source. In FIG. 23, parts corresponding to those in FIG.
An information display unit 5 and push buttons 303, 305, 307, and 309 for setting an original image area are arranged on the surface of the housing 3 constituting the display device 301 shown in FIG.

A mechanism unique to the display device 301 shown in FIG. 25 is four push buttons 303, 305, 307, and 309. By pressing these four push buttons 303, 305, 307, and 309, the corresponding position can be moved in a specified direction.
In the case of this form example, as in the case of form example 3, an original image region 11 having an arbitrary size can be set at an arbitrary position on the information display unit 5.

  In the case of FIG. 25, the push button 303 is used to input a start position (upper end position) of the original image area 11 in the vertical direction. In the case of this embodiment, the push button 303 includes two buttons: a button for moving the start position upward in the vertical direction and a button for moving the start position downward in the vertical direction.

  On the other hand, the push button 305 is used to instruct and input the end position (lower end position) of the original image area 11 in the vertical direction. In the case of this embodiment, the push button 305 includes two buttons: a button for moving the end position upward in the vertical direction and a button for moving the end position downward in the vertical direction.

  The push button 307 is used to instruct and input the start position (left end position) of the original image area 11 in the horizontal direction. In the case of this embodiment, the push button 307 includes two buttons, a button for moving the start position to the left in the horizontal direction and a button for moving the start position to the right in the horizontal direction.

  The push button 309 is used to instruct and input the end position (right end position) of the original image area 11 in the horizontal direction. In the case of this embodiment, the push button 309 includes two buttons: a button for moving the end position to the left in the horizontal direction and a button for moving the end position to the right in the horizontal direction.

(D-2) Functional Configuration of Display Device FIG. 26 shows a functional configuration example of devices that constitute the display device 301. In FIG. 26, parts corresponding to those in FIG.

  The display device 301 includes a timing controller 21, a partial area setting user interface (UI) 311, a display area decoder 313, a partial area setting unit 27, an image data selection unit 29, a black data supply unit 31, a gate scan driver 33, a line The driver 35 and the organic EL display panel 37 are sequentially formed.

In other words, except for the partial area setting user interface (UI) 311 and the display area decoder 313, the same ones as in the third embodiment are used.
In the case of this embodiment, the partial area setting user interface (UI) 311 includes push buttons 303, 305, 307, and 309 and an internal mechanism that detects the operation amount (for example, the number of times of pressing and the pressing time).

  The operation amount detection device corresponding to the push buttons 303 and 305 includes a pulse generator that shifts the output phase of the start position pulse and the end position pulse in the operation direction. For example, when the moving direction is the screen upper direction, the start position pulse and the end position pulse are shifted in the direction in which the output phase advances, and when the moving direction is the screen lower direction, the start position pulse and the end position pulse are directions in which the output phase is delayed. Shifted to.

  On the other hand, the operation amount detection device corresponding to the push buttons 307 and 309 includes a pulse generator that shifts the output phase of the start position pulse and the end position pulse in the operation direction. For example, when the movement direction is the left direction of the screen, the start position pulse and the end position pulse are shifted in the direction in which the output phase advances, and when the movement direction is the right direction of the screen, the start position pulse and the end position pulse are directions in which the output phase is delayed. Shifted to.

  The output phases of the two start position pulses and the two end position pulses corresponding to these four push buttons 303, 305, 307, and 309 correspond to the operation positions of the operators 203, 205, 207, and 209 in the third embodiment (digital Value).

The display area decoder 313 executes processing for converting the output phases of the start position pulse and the two end position pulses into information representing the pixel position on the display panel.
27 and 28 show the mechanism of the conversion process executed by the display area decoder 313. FIG.

  FIG. 27 shows a mechanism used when the phase of the start position pulse and the end position pulse in the vertical direction of the original image area 11 is converted into the pixel position of the display panel. When detecting the pixel position in the vertical direction, the display area decoder 313 specifies the edge position of the original image area 11 based on the count value of the H sync counter at the falling timing of the start position pulse and the end position pulse.

  The H sync counter is a counter that starts counting H sync in synchronization with V sync. In this example, the count value is counted in the range of 0-11. In the case of FIG. 27, the count value corresponding to the start position of the original image area 11 is “3”, and the count value corresponding to the end position of the original image area 11 is “8”.

  FIG. 28 shows a mechanism used when the phase of the start position pulse and the end position pulse in the horizontal direction of the original image area 11 is converted into the pixel position of the display panel. When detecting the pixel position in the horizontal direction, the display area decoder 313 specifies the edge position of the original image area 11 based on the count value of the clock counter at the falling timing of the start position pulse and the end position pulse.

  The clock counter is a counter that starts counting the dot clock in synchronization with the H sync. In this example, the count value is counted in the range of 0-15. In the case of FIG. 28, the count value corresponding to the start position of the original image area 11 is “4”, and the count value corresponding to the end position of the original image area 11 is “9”. With this procedure, information that gives the edge position of the original image area 11 is supplied to the partial area setting unit 27.

(D-3) Change of Display Screen by Push Button Operation FIGS. 29 to 31 show display screen examples of the display device 301 equipped with the display technology described above.
FIG. 29 is a display screen example when the start position and end position of the original image area 11 are set inside the information display section 5 only in the vertical direction. In the figure, the push button to be operated is colored. In this case, black screens appear on the upper and lower sides of the information display unit 5, and only the vicinity of the center of the original image is displayed in full size in the horizontal direction.

  FIG. 30 shows an example of a display screen when the start position and end position of the original image area 11 are set inside the information display section 5 only in the horizontal direction. In the figure, the push button to be operated is colored. In this case, black screens appear on the left and right sides of the information display unit 5, and only the vicinity of the center of the original image is displayed in full size in the vertical direction.

  FIG. 31 is an example of a display screen when the start position and end position of the original image area 11 are set inside the information display section 5 in each of the horizontal direction and the vertical direction. In the figure, the push button to be operated is colored. In this case, the original image is displayed only in the central portion of the information display unit 5, and a black screen is displayed around the original image.

  As described above, also in this embodiment, the area where the original image is displayed as it is is the push button 303, 305 operated by the user regardless of the display content of the original image (irrespective of the system control unit). , 307, and 309.

  That is, even during the display of the screen, it is possible to display only the screen area that the user has positively or actively determined, and to switch the other screen areas to the black screen display. In addition, in the case of this embodiment, the position and size of the original image area 11 can be freely set, so that the user's intention can be further reflected in the screen configuration.

  Of course, since the organic EL element is a self-luminous element, it is possible to prevent the drive current from flowing through the organic EL element located in the black screen region, and the power consumption can be greatly reduced. As a result, the time during which the display device 1 can be driven by a battery power source can be lengthened.

  In the case of this embodiment, the case where the movable mechanism used for setting the original image area 11 is a push button is exemplified, but a dial that can be rotated in both directions may be used. Further, a mechanism for shifting the pulse for giving the edge position only in one prescribed direction may be adopted. In this case, a shift amount that is reset to 0 (zero) when the shift amount reaches a certain amount may be used.

(B) Other embodiment examples (B-1) Other image data examples suitable for output to the power saving area In the above-described embodiment examples, all are set by the user in order to maximize the power consumption reduction effect. The case where a black image is output to an area other than the original image area 11 has been described. That is, the case where the gradation values of R (red) data, G (green) data, and B (blue) data corresponding to each pixel located in the power saving region 13 are all set to 0 (zero) has been described. .

  However, the power saving effect can be realized without necessarily outputting a black screen. That is, a power saving effect can be realized if even an image with low power consumption can be displayed as compared with the case where the original image is displayed as it is. If power saving can be realized, a method for generating an image to be output to the power saving area 13 is arbitrary. In the following, a description will be given of a processing method in which the power consumption is surely smaller than that of the original image while being relatively simple processing.

(A) Processing example 1
Here, a method of generating image data in which the emission luminance value of the original image data is uniformly reduced and outputting the generated image data in place of the original image in the power saving area 13 will be described.

  FIG. 32 shows a functional configuration example of a display device equipped with this type of replacement image data generation unit. FIG. 32 is a functional configuration example in the case where the technology is applied to the display device 201 described in the third embodiment.

  32 includes a timing controller 21, a partial area setting user interface (UI) 211, a display area decoder 213, a partial area setting unit 27, an image data selection unit 29, a luminance reduction unit 401, a gate scan driver. 33, a line sequential driver 35 and an organic EL display panel 37.

  The luminance reduction unit 401 is a processing device that receives the original image data from the timing controller 21 and generates image data in which the luminance value is uniformly reduced.

  The luminance reduction unit 401 includes a data format conversion unit that converts image data in RGB format into a format of luminance data and color difference data, a luminance data conversion unit that reduces luminance data values at a predetermined ratio, and a conversion This can be realized by a data format conversion unit that converts luminance data and color difference data later to image data in RGB format.

Of course, a conversion table storing the input / output relationship corresponding to the same function can also be used.
In the case of this embodiment, the luminance other than the original image area 11 is lowered. That is, the image quality other than the attention area designated by the user can be reduced.
FIG. 33 shows an example of a display screen corresponding to the difference in luminance reduction rate.

  When this processing example is adopted, it is possible to display a screen on which the information on the original image in the image quality degradation region can be confirmed to some extent in addition to the power saving effect corresponding to the luminance reduction ratio. In addition, it is possible to reduce a sense of incongruity felt by the user as compared with a case where a black screen is output.

(B) Processing example 2
Here, a method will be described in which image data obtained by monochromaticizing original image data is generated, and the generated image data is output in place of the original image in the power saving area 13.

FIG. 34 shows a functional configuration example of a display device equipped with this type of replacement image data generation unit. Note that FIG. 34 is a modification of Processing Example 1.
34 includes a timing controller 21, a partial area setting user interface (UI) 211, a display area decoder 213, a partial area setting unit 27, an image data selection unit 29, a color reduction unit 501, and a gate scan driver. 33, a line sequential driver 35 and an organic EL display panel 37.

  The color reduction unit 501 receives original image data from the timing controller 21, outputs only image data of predetermined color components, and replaces the image data of the other two color components with black data (0 data). It is a processing device. By this conversion process, the number of organic EL elements that emit light is surely reduced to 1/3. Therefore, not only the light emission luminance is lowered, but also an effect of reducing power consumption is expected.

  Even in the case of adopting this processing example, although the image quality of the image displayed in the power saving area 13 is degraded, a screen on which the information of the original image can be confirmed to some extent can be displayed. Here, the case where only the image data for one color is left has been described, but a method of leaving only the image data for two colors (that is, excluding the image data for one color) may be applied.

(C) Processing example 3
Here, a method of outputting replacement image data generated so as to be always smaller than the average picture level of the original image data corresponding to the power saving area 13 in place of the original image in the power saving area 13 will be described.

  FIG. 35 shows a functional configuration example of a display device equipped with this type of replacement image data generation unit. FIG. 35 is also a functional configuration example in the case where the technology is applied to the display device 201 described in the third embodiment.

The APL calculation unit 601 is a processing device that calculates an average picture level of original image data corresponding to a region other than the set partial region.

  The APL calculation unit 601 is realized by a data conversion unit that converts image data in RGB format into a data format of luminance data and color difference data, and an arithmetic unit that calculates an average value of luminance data corresponding to the power saving region 13. can do.

The replacement image data generation unit 603 is a processing device that generates replacement image data having an average picture level smaller than the calculated average picture level.
The replacement image data generation unit 603 is realized by a processing circuit that generates image data in the RGB format based on a picture level smaller than the calculated picture level.

  Alternatively, the replacement image data generation unit 603 uses a processing circuit that generates an image in which a part of the original image data in a range corresponding to the partial area is replaced with a black level image so as to be equal to or less than the calculated average picture level. Realize.

  In the case of the above-described example, the power saving area 13 displays a gray image with a single brightness on the entire screen or an image quality obtained by replacing a part of the original image with a black screen. In addition, when the replacement image data is generated using another processing method, an image whose image quality is greatly deteriorated with respect to the original image is displayed. In any case, the power saving effect can be realized for the entire screen.

(B-2) Battery Driven Device In the above-described embodiment, the display device has been described as an example of the battery drive device.
