JP-A-7-261919

  As shown in FIG. 11, performing menu selection by relatively many key operations has a problem that the operation is complicated and takes time. That is, it is necessary to press the key many times before selecting a desired item, which is troublesome.

  In addition, Patent Document 1 discloses that menu operation is performed using a laser beam emitting unit called a laser pointer. I could not say.

  The present invention has been made in view of such a point, and an object thereof is to make it possible to easily perform a display operation such as a menu screen.

  The present invention is applied to a display device including a light incident detection unit that detects an incident coordinate of light having a predetermined intensity or more on a display surface of a display unit, and a remote control signal receiving unit. Then, the process displayed at the incident coordinate position detected by the light incident detection unit is selected, and the execution of the selected process is determined according to the remote control signal received by the receiving unit.

  Further, the remote control signal receiving unit may be provided in another video device and execute processing in the video device.

  As a result, the remote control device has a laser light output unit and a remote control signal output unit such as an infrared signal so that the menu screen can be operated by operating this remote control device. Become.

  According to the present invention, the remote control device includes a laser light output unit and a remote control signal output unit such as an infrared signal, so that the menu screen can be easily operated by operating the remote control device. It becomes possible.

  In addition, it becomes possible to select the position of the cursor displayed on the screen and to confirm the operation at the selected position as a pointing device.

  Furthermore, it is possible to operate a separate video device connected to the display device.

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a diagram showing a system configuration example of the example of the present embodiment. In this example, it is an example applied to the display device 10 as a television receiver. The display device 10 includes a display panel 20 and can display an image. In the example of FIG. 1, the menu screen 21 is displayed as an example. Further, the display device 10 includes an infrared light receiving unit 11 serving as a remote control signal receiving unit on the side of the display panel 20. Further, the display panel 20 of the present example is configured to detect light input to the display surface.

  With reference to FIG. 2, an internal configuration of the display device 10 will be described. The display device 10 includes a video input unit 16, sends a video signal input to the video input unit 16 to the display processing unit 17, and causes the display processing unit 17 to display a video on the display panel 20. I do. The video input unit 16 may include a tuner and receive a broadcast signal. Display control is performed under the control of the display control unit 15, and auxiliary display control such as a menu screen is also performed under the control of the display control unit 15.

  The infrared signal received by the infrared receiver 11 is converted by the remote control signal code converter 12 into a control code corresponding to the received infrared signal, and the data of the control code is sent to the execution content controller 14. The execution content control unit 14 controls the operation of the display device corresponding to the supplied control code.

  Further, the display device 10 of this example is configured to be able to detect the input of light from the outside to the display surface of the display panel 20. An example of the detection configuration will be described later. When the input of this light is above a certain intensity, the laser light detection unit 23 detects the input of the laser light. When the laser light detection unit 23 performs corresponding detection, the coordinate detection unit 13 determines which coordinate position on the display surface is incident, and sends the data of the determined coordinate position to the execution content control unit 14.

  FIG. 3 shows an example of the principle of performing display and light input detection on the display panel 20. In this example, an EL (electro-luminescence) display panel is used as the display panel 20. An EL display panel emits light when a signal is applied to a light emitting element (EL element), but the EL element itself also has a function as a light receiving element. By setting the light emitting period and the light receiving period in a time-sharing manner, only the display can be performed. In addition, light input can be detected.

  FIG. 3A is a diagram showing a driving configuration of an EL element of one pixel of the EL display panel. At the time of display (during light emission), as shown in FIG. 3A, an ON signal is supplied to the gate 93G of the switching element (TFT transistor) 93 disposed at the intersection of the source line 91 and the gate line 92, and the source A drive signal is passed from 93S to the drain 93D, and a drive signal for the pixel is applied to the counter electrode 95 via the EL element 94.

  Then, as shown in FIG. 3B, at the time of detecting the incidence of light, the EL element 94 is used as a light receiving element, and a signal accumulated by receiving light in the EL element 94 is read from the drain 93D to the source 93S, and the source line Take out from 91 to the outside.

  By performing the display process shown in FIG. 3A and the light receiving process shown in FIG. 3B in a time-sharing manner within one display frame, for example, display and incident light detection can be performed simultaneously. The example in FIG. 3 is an example in which an EL panel is used as a display panel. However, in the case of a liquid crystal display panel, for example, a light receiving element is arranged separately from the elements constituting the display pixel, and display is performed in a time division manner. By performing display by the element and detection of light reception by the light receiving element, it is possible to constitute a display device that can detect the same incident light.

  FIG. 4 is a diagram showing an example of the shape of the remote control device 30 of this example. The remote control device 30 includes a menu screen operation key 31, and includes a laser light emitting unit 33 and an infrared light emitting unit 34 that are signals emitted by the operation of the key 31. Various keys other than the key 31 may be arranged as operation keys. For example, a key for turning on / off the display of the menu screen may be prepared.

  FIG. 5 is a diagram showing an example of the internal configuration of the remote control device 30. When the key 31 is operated (pressed), the control unit 32 outputs laser light from the laser light emitting unit 33 while the key 31 is being pressed, and at the timing when the key 31 is no longer pressed. From the infrared light emitting unit 34, a remote control signal (infrared signal) of a code for confirming operation is output. Further, by operating other keys (not shown), a remote control signal of a code corresponding to each key is output from the infrared light emitting unit 34.

  FIG. 6 is a flowchart showing an example of a signal output state when the key 31 of the remote control device 30 is operated. First, the control unit 32 determines whether or not the key 31 has been pressed (step S11), and when determining that the key 31 has been pressed, starts the output of laser light from the laser light emitting unit 33 (step S12). When the pressed state continues, the laser beam is continuously output. And the control part 32 judges whether it was no longer in the pressed state (step S13). If it is determined that the button is no longer pressed, the infrared light emitting unit 34 outputs a remote control signal (infrared signal) of a confirmation operation code (step S14).

  Next, an operation example in the display device 10 that receives (receives) a signal transmitted from the remote control device 30 will be described with reference to a flowchart of FIG. First, the execution content control unit 14 determines whether or not the current state is a menu screen display mode (step S21). Here, when it is determined that the display mode is the menu screen display mode, it is determined whether or not laser light is received from the output of the coordinate detection unit 13 (step S22). The coordinate position where the laser beam is received is determined (step S23). Thereafter, it is determined whether or not the remote control signal of the fixed code is received (step S24). If the corresponding code is received, the display item in the menu screen displayed at the coordinate position determined in step S23. And the display item is executed (step S25).

  Thereafter, it is determined whether or not there is an operation for ending the menu display (step S26). If there is no operation to end the menu display, the process returns to step S22 to determine whether or not there is a next light reception of the laser beam. If it is determined in step S22 that no laser beam is received, or if it is determined in step S24 that no confirmed code is received, the process proceeds to step S26.

  In this way, the operation of the menu screen can be performed very easily by performing the operation on the menu screen based on the detection of the received light of the laser beam and the detection (reception) of the remote control signal. In other words, the user presses the key 31 of the remote control device 30 to emit laser light, and the irradiation position 22 on the screen of the laser light is the item to be selected on the menu screen 21 as shown in FIG. To be. In this state, pressing the key 31 is stopped to stop the emission of the laser beam, and at the same time a remote control signal for confirmation is output, and the corresponding display item is selected by receiving (receiving) the signal. Menu operation will be performed. Therefore, the operation of the menu screen can be improved by performing a very simple operation by simply pressing one key and aligning the position of light to be irradiated.

  In the examples of FIGS. 4 and 5, the laser light is turned on / off and the confirmation remote control signal is output only by operating one key 31. Alternatively, only the laser light may be turned on / off, and the confirmation remote control signal may be output by another key operation.

  In the example described so far, the present invention is applied to the operation of the menu screen, but may be applied to other operations related to display. For example, when a cursor is displayed on the screen, an instruction for the display position of the cursor and an operation for confirming the position indicated by the cursor may be performed by the same process.

  FIG. 8 is a diagram showing an example of this case. A cursor display 29 is displayed on the display panel of the display device 10 '. The display position of the cursor display 29 is configured to be performed at the laser light irradiation position 22. At the same time, the confirmation operation is performed with a remote control signal. The remote control device 30 may be the same as the example in FIG.

  FIG. 9 is a flowchart showing an example of operation control in that case. First, the execution content control unit 14 determines whether there is laser light reception from the output of the coordinate detection unit 13 (step S31). If there is laser light reception, the coordinate position where the laser light is received is determined. Determination is made (step S32), and the cursor display position is moved to the determined position (step S33). Thereafter, it is determined whether or not the remote control signal of the fixed code is received (step S34). If the corresponding code is received, a process corresponding to the click of the display button at the cursor display position is executed. (Step S35), the process returns to Step S32. If it is determined in step S34 that no remote control signal is received, the process returns to step S32.

  In this way, the cursor display can be moved and clicked based on the detection of the reception of the laser beam and the detection (reception) of the remote control signal, thereby improving the operability of the operation by the cursor display. Can do.

  Next, a second embodiment of the present invention will be described with reference to FIG. In the case of this example, a video recording / reproducing device 40 which is a separate video device is connected to the display device 10 by a cable 42.

  When the video recording / reproducing apparatus 40 is operated, the video signal of the menu screen generated in the video recording / reproducing apparatus 40 is sent to the display apparatus 10 via the cable 43 and displayed on the display apparatus 10. When receiving the laser beam, the display device 10 of this example sends the data of the coordinate position of the laser beam irradiation point 22 and the confirmed information by infrared rays received at 11 to the video recording / reproducing device 40 via the cable 42. As a configuration. Note that the cable 42 and the cable 43 may be realized by the same cable.

  Then, in the video recording / reproducing apparatus 40, when the coordinate position data is supplied from the display apparatus 10 while the video signal of the menu screen is being output, the menu is based on the supplied coordinate position data. When an item on the screen is selected, and the infrared signal light receiving unit 41 subsequently receives (receives) the remote control signal of the confirmation code, the selection of the item is confirmed. Other configurations and processes are the same as those in the first embodiment described above.

  With the configuration shown in FIG. 10, even a video device different from the display device can be operated by a laser beam and a remote control signal, and operability is improved.

  In each of the embodiments described so far, the infrared signal is used as the remote control signal. However, the remote control signal may be transmitted using another wireless signal (radio wave signal).
