As described above, the optical sensor unit 6 is provided between the pixel electrodes 19. The display device 1 is configured by the above-described components.

Next, the operation of the display device 1 will be described with reference to FIGS. In these figures, first, the user turns on the power switch (not shown) of the display device 1.
In response, the display unit 5 displays an initial screen. The information receiving unit 8 receives, for example, Internet information via the ISDN line, and the display unit 5 displays the information (FIG. 1).
See).

If the user is interested in the above screen, he / she tries to move to the next related screen. Therefore, the user needs the remote control 2
And press the start button 3. As a result, the remote controller 2 emits, for example, red visible laser light 7 to the display unit 5. Then, the user uses the visible laser light 7 to select a desired area of the display unit 5 (for example, the specific display area 29 and C
(displayed as "lick").

At this time, the visible laser light 7 has not been modulated yet. Then, for example, a point irradiated by the visible laser light 7 is a pixel electrode 19 (B in FIG.
Point). Due to this irradiation, the portion C of the optical sensor unit 6 near the pixel electrode 19 detects the light output value. Then, the optical sensor unit 6 outputs an optical output value (voltage value or current value) to the control unit 9.

However, the control unit 9 is configured to detect only the modulated visible laser light. Therefore, at this time, not only the visible laser light 7 but also the light from the backlight 11 and the outside light (light emitted from the indoor lighting fixture) are incident on the optical sensor unit 6, but the control unit 9 "Modulated laser light has entered" is not recognized (detected).

As described above, when the user visually confirms that the irradiation position of the visible laser light 7 coincides with the specific display area 29, the user presses the click button 4 of the remote controller 2. At this time, the modulation unit of the remote controller 2 emits a digital pulse modulation signal (modulated laser light) of about 50 KHz by a binary signal of Hi (1) and Lo (0).

At this time, the display unit 5 is driven by a normal driving method. That is, in the display section 5, each scanning electrode 17 is scanned from left to right at 50 to 100 Hz, for example. Further, video data is sequentially input to each signal electrode 20. Thus, the display unit 5 is driven by the TFT 21 in the active matrix system.

At this time, assuming that the point B is irradiated with the modulated laser light (see FIG. 3), a voltage is first applied to the first scanning electrode 17a. At this time, the portions D and E of the optical sensor portion 6 located above the scanning electrode 17a do not detect the modulated laser light.

Next, a voltage is applied to the second scanning electrode 17b to cause the display section 5 to perform a normal display. At this time, each output terminal 24a, 24b of each detection electrode 24 is
The light output value is output to the control unit 9. Specifically, the F section of the optical sensor section 6 located above the scanning electrode 17b does not output a light output value. Further, a portion C of the optical sensor portion 6 located on the left side of the point B irradiated by the modulated laser light and above the scanning electrode 17b is modulated by the control portion 9 via the detection electrode 24b. The output light value (voltage value) is output.

As a result, the control section 9 detects that the pixel electrode 19 (point B) in the second row and the second column is irradiated with the modulated laser light. As described above, the control unit controls the second scan electrode 1
Since the light output value was detected via the detection electrode 24 during scanning of 7b, it is recognized that the pixel electrode 19 at the point B is in the second row. At this time, since the control unit has detected the light output value via the second detection electrode 24b, it recognizes that point B is in the second column.

Further, a voltage is applied to the third scan electrode 17c. At this time, the output terminal 24 of each detection electrode 24
a and 24b do not output an optical output value to the control unit 9. In this manner, the fourth and subsequent scanning electrodes 17 are sequentially scanned, and a predetermined display is performed.

In summary, the scanning electrodes 17a, 17b, 17c,...
Scan. Then, the scanning electrodes 17a, 17b, 17
The outputs of the plurality of detection electrodes 24a, 24b,..., 24n,. For example, when scanning the scanning electrode 17m,
The light output value is output to the control unit 9 via the detection electrode 24n. As a result, the control unit 9 recognizes that the pixel electrode 19 (point B) on the n-th row and the m-th column is irradiated with the modulated laser light. As described above, the control unit 9 obtains the irradiation position of the modulated laser light.

Next, the control section 9 obtains the range of the pixel electrode 19 in the specific display area 29 in the display section 5. For example, the coordinates of the corners G1, G2, G3, G4 of the specific display area 29 are obtained. For example, G1 (1600, 600), G2 (1
600, 900), G3 (1800, 600), G4
It is assumed that (1800, 900) is obtained.

Then, the control section 9 determines whether or not the irradiation position B (the n-th row, the m-th column) of the modulated laser light obtained by the measurement is within the specific area 29. For example, the control unit 9
Recognizing that 1600 <n <1800 and 600 <m <900, affirms the above determination.

As a result, the control unit 9 sends the specific display (CLI)
ck). For example, a screen following the screen of the display unit 5 shown in FIG. 1 is displayed.

The above contents will be summarized. The specific display area 29 of the display unit 5 is irradiated with laser light (for example, modulated laser light or the like). Then, the control unit 9 performs a process (for example, displaying a screen of the next page) based on the output (light output value) of the optical sensor unit 6 according to the specific display (Click or the like).

The remote controller 2 emits invisible laser light (for example, infrared light) and outputs to the control unit 9 that the optical sensor unit 6 has detected the light. The control unit 9 may obtain the position coordinates at which the invisible laser light is irradiated, and display the pointer 30 (visible) on the display unit 5 according to the coordinates. This is the end of the description of the display device 1.

Next, a display device 31 according to the second embodiment of the present invention will be described with reference to FIGS. 5 is a side view of the display device 31, FIG. 6 is a structural diagram of a remote controller 32 used for the display device 31, FIG. 7 is a front view of the display device 31, and FIG.

In these figures, the remote controller 32 has a light emitting section 33, a beam splitter 34, a first lens 35 and the like. The light emitting unit 33 emits, for example, a visible laser beam. The visible laser beam passes through a beam splitter 34, is collected by a first lens 35, and is emitted as a first laser beam 36 (see FIG. 6).

Further, the remote controller 32 has a reflection plate 37, a fulcrum 38, a driving device 39, a second lens 40 and the like. The reflecting plate 37 is arranged in an oblique state near the beam splitter 34. The lower end of the reflector 37 is a fulcrum 38
And the vicinity of the upper end of the reflection plate 37 is fixed to a drive device (for example, a cylinder or the like) 39.

With the above configuration of the remote controller 32, when the user moves the operation lever 42 to the right, for example, the tip of the driving device 39 linked to the operation lever 42 moves upward (see FIGS. 5 and 6). . In this way, the reflector 37
Is steep. Then, the laser light emitted from the light emitting section 33 travels rightward by the beam splitter 34, is reflected by the reflection plate 37, is collected by the second lens 40, and is emitted as the second laser light 41.

At this time, as described above, since the inclination angle of the reflection plate 37 is steep, the angle H sandwiched between the first laser light 36 and the second laser light 41 is small.

When the user moves the operation lever 42 to the left, for example, the tip of the driving device 39 moves downward. In this way, the slope of the reflection plate 37 becomes gentle. At this time, the third laser light 43 emitted from the light emitting unit 33 and passing through the beam splitter 34 and the first lens 35
And the angle I sandwiched between the beam splitter 34 and the fourth laser beam 44 passing through the second lens 40 is large.

As described above, the remote controller 32 controls at least two laser beams (36, 41, 43,
4) so that the emission angles (for example, angles H and I) of each laser beam can be changed.

In the display section 5a, for example, the specific display area 4
5 and 46 are displayed three-dimensionally, and the one with the smaller depth is the first
As the specific display area 45, the one with the larger depth is displayed as the second specific display area 46.

When the user pushes the operation lever 42 rightward, the first laser light 36 and the second laser light 41 having a small emission angle H between the laser lights are obtained. At this time, the laser beams 36 and 41 coincide with the first specific display area (corresponding to 45 in FIG. 5 and the point J1J2 in FIG. 7).

Further, when the user pushes the operation lever 42 to the left, the third emission angle I between the laser beams is increased.
A laser beam 43 and a fourth laser beam 44 are obtained. At this time, the laser beams 43 and 44 coincide with the second specific display region (corresponding to 46 in FIG. 5 and points K1 and K2 in FIG. 7).
In this way, by changing the emission angles of the laser beams, it is possible to correspond to the specific display areas provided on the display unit and having different depth lengths.

Further, in FIG. 8, the display section 5a is, for example,
The operation knob 47 and the like are displayed. The third laser beam 43 emitted from the remote controller 32 irradiates the upper end of the operation knob 47,
The fourth laser beam 44 emitted from the remote controller 32 irradiates the lower end of the operation knob 47.

When the user rotates the remote control 32, the operation knob 47 is rotated, and the control unit 9 performs processing according to the rotation of the operation knob 47 (for example, by rotating the operation knob 47, a special menu display is performed). Etc.) can be performed.

Finally, the display device 48 according to the third embodiment of the present invention will be described with reference to the perspective view of FIG. In FIG. 9, a remote controller 49 includes a modulating unit, a laser light emitting unit, a light emitting diode light emitting unit, a control unit, a battery unit (all not shown), a start button 3, a click button 4, and the like. Have been.

The display section 5b has, for example, a specific display area 50 displayed at an appropriate position on the screen, and an infrared receiving section 51 and the like provided outside the screen. The infrared receiving unit 51 includes, for example, a light receiving element and is disposed on the display unit 5b.

The laser light emitting section emits, for example, visible laser light, and the light emitting diode light emitting section emits, for example, infrared light. As described above, the infrared light emitted from the light emitting diode light emitting portion has a wider emission range (less directivity) than the visible laser light.

Next, the operation of the display device 48 will be described with reference to FIG. In FIG. 9, the user has a remote control 49,
Press start button 3. Then, the remote controller 49 emits visible laser light to the display unit 5b. Next, the user searches for (points to) a desired area (for example, the specific display area 50) of the display unit 5c with the visible laser light 52.

As described above, when the user visually confirms that the irradiation position of the visible laser beam 52 matches the specific display area 50, the user presses the click button 4 of the remote controller 2. At this time,
The remote controller 49 emits the modulated infrared light 53 to the display unit 5b by the light emitting diode light emitting unit and the modulation unit provided on the remote controller 49.

Since the modulated infrared light 53 has a wider emission range than the visible laser light, the infrared light 53 irradiates the infrared receiver 51 provided on the display unit 5b. As a result, the control unit 9 performs a process (for example, key input for starting the display of the display unit 5b) by turning on the infrared receiving unit 51. As described above, since the emission range of the infrared ray 53 is relatively wide, key input or the like can be performed even when the pointer (infrared ray receiving section 51) is outside the screen.

The above contents are summarized. The remote controller 49 emits light having a wider emission range than the laser light 52 (for example, infrared light 53).
Is emitted. The light (for example, infrared rays 53) is emitted at least when the position is determined after a point (such as at the time of a click operation).
