Description of the Invention: [Technical Field of the Invention] The present invention relates to a display device having an image detecting function. [Prior Art] A flat panel display of the prior 'scanner body type is well known. When the image is scanned, the device transmits the backlight from the display screen to illuminate the scanned object and reflects "the reflected light generated at this time is sensed by the light receiving elements of the respective pixels. Thereby, the arrangement surface of the components disposed on the top surface of the flat panel display is scanned as an image. An example of such a display has been disclosed in Patent Document 1. Touch panels using this technology are also known. In the case where a certain operation is performed by the touch panel, generally, a so-called multi-touch detection is performed by detecting touches at different positions of the plurality of touch panels. Thereby, the user can perform various operations on the information processing apparatus having the touch panel by using multiple touches. [PRIOR ART DOCUMENT] [Patent Document 1] [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei 6-186585 (published on Jul. 8, 1994). However, in the prior art device, since it is used for the backlight (4) (four) image detection of the screen display, in the state where the display screen is dimmed, it is impossible to ensure the illumination light of sufficient brightness required for detecting the touch point. 142699.doc 201017275 And in order to stabilize the detection accuracy, when black is displayed on the screen, it is necessary to display black which has a certain brightness instead of being completely black, and thus the displayed black will be halo. Further, when detecting the shape of the component in contact with the screen or the pattern printed on the component, if the scanning speed of the image detection is slow, the screen will flash and flash, which causes a problem that is very difficult to view. The present invention has been made in an effort to solve the above problems, and an object thereof is to provide a display device having an image detecting function which can prevent floating black at the time of image detection and prevent flickering of the face when the detection speed is lowered. [Means for Solving the Problem] In order to solve the above-described problems, the display device of the present invention is characterized in that it includes a display panel and a display device that detects an image through a display screen of the display panel, and includes: a visible light irradiation mechanism The visible light is radiated to the outside from the display screen; the invisible light irradiation mechanism radiates invisible light from the display screen to the outside; and the invisible light receiving mechanism is formed in a plurality of pixels constituting the display panel. Each pixel receives the reflected light of the invisible light. According to the above configuration, the display device receives the reflected light of the invisible light (e.g., ultraviolet light or infrared ray) that is transmitted through the display surface of the display panel, thereby detecting the image of the detection target. That is, the image detection is not performed by visible light, and therefore the detection accuracy can be stabilized even if the brightness of the backlight of the visible light is lowered in order to dim the screen. As a result, 142699.doc 201017275 prevents the display image from floating black. Further, even in the case where the detection speed is lowered, since the visible light that is not used for the face display is used for the detection, the blinking of the screen does not occur. As described above, the present display device can prevent blackening at the time of image detection, and can prevent the brightness of the screen from flickering when the detection speed is lowered. The structure of the display device can be variously modified. For example, the visible light irradiation means may be a light-emitting element that is provided on each of the pixels and that emits visible light. Alternatively, the visible light irradiation means may be a visible light transmitting means for illuminating the visible light and a visible light transmitting means for transmitting the visible light irradiated by the backlight. Further, the invisible light irradiation means can be used as a light-emitting element that is provided on each of the pixels and that emits invisible light. Alternatively, the invisible light irradiation means may be a backlight portion that illuminates invisible light and an invisible light transmitting means that transmits invisible light that is irradiated by the backlight portion. [Effect of the Invention] As described above, the display device of the present invention can prevent the blackening at the time of image detection, and can prevent the brightness of the screen from flicking when the detection speed is lowered. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to Figs. 14 to 14 . (Device Configuration) Fig. 2 is a block diagram showing the configuration of the main part of the display device 1 of the present invention. As shown in the figure, the display device W includes a display panel 2, a detection processing unit 4, a display processing unit 6, a detection setting unit 8, an image analysis unit 1 (), a processing execution unit 12, and an input/output unit 14. ° 142699.doc 201017275 The display panel 2 is a panel that displays information such as text and images on the screen, such as a liquid crystal display panel, an organic EL panel, a plasma display, or an FED (field emission display). The detailed internal structure of the display panel 2 will be described later. The display panel 2 has an image detecting function, and in the display device 由, the detection processing unit 4 controls image detection on the screen of the display panel 2. On the other hand, the display processing unit 6 controls the display of information on the screen of the display panel 2. The detection setting unit 8, the image analysis unit 1A, and the processing execution unit 12 will be described later. The detection processing unit 4, the display processing unit 6, the detection setting unit 8, the image decomposing unit 10, and the processing executing unit 12 constitute a specific driver circuit. input Output. The P 14 system contains input and output terminals for displaying information input, output of detection information, and control. FIG. 1 shows the internal structure of the display panel 2. As shown in the figure, the display panel 2 is arranged in a matrix, and includes a plurality of pixels 20, which are basic units of display, and each pixel 20 includes an invisible light emitting unit 22, an invisible light receiving unit 24, and an R light emitting unit 26. G light-emitting portion 28 and B light-emitting portion 30. The invisible light emitting unit 22, for example, a light-emitting element, transmits the invisible light to the outside of the display device through the display panel 2. The invisible light receiving portion 24, such as a photoelectric crystal, receives invisible light incident on the display panel 2. r The light-emitting portion 26 is, for example, a light-emitting element that emits red light. The G light-emitting portion "for example, a light-emitting element that emits green light. The B light-emitting portion 3, for example, a light-emitting element" is emitted. On the display panel 2, the invisible light-emitting portion 22 and the invisible light-receiving portion are used - in the prior The display device is disposed at a place where a shadow mask is formed. The display panel 2 142699.doc -6-201017275 realizes a display function using visible light by the R light-emitting portion 26, the G light-emitting portion 28, and the light-emitting portion 3A. That is, the display panel 2 has a configuration in which the invisible light emitting portion 22 and the invisible light receiving portion 24 are provided in addition to the light emitting portions 26 to 30 of the three primary colors. The invisible light refers to light of a wavelength other than visible light, specifically, infrared light, Far infrared ray, ultraviolet ray, etc. In the display panel 2 'invisible light is irradiated by the invisible light emitting portion 22. If a member that reflects invisible light is disposed on the screen of the display panel 2, the invisible light is reflected back by the member. Into the display panel 2. The reflected invisible light reaches the invisible light receiving portion 24, and the brightness of the reflected invisible light is detected by the invisible light receiving portion 24. The display panel 2 is not visible. Since the light-receiving portion 24 is formed in a quadratic planar shape, the image of the invisible light-receiving portion 24 is processed to transmit an image through the top surface of the display panel 2. As described above, the display device 1 is disposed behind the display panel 2. The image is detected by the invisible light on the surface. Therefore, even if the brightness of the visible light is low, the detection can be performed steadily. Thus, the floating black generated in the prior art can be avoided. Moreover, even in the case where the detection speed is lowered, due to the detection The invisible light that is not displayed on the face is used, so that the screen does not flicker. (Detection setting process) The display device 1 detects the incident pixel by the invisible light detecting unit disposed in each pixel 20. According to the detection result, the touch position of the face of the display panel 2 is determined, and the image of the touch position is detected. If there is a certain degree of brightness around the panel 2, the display surface is displayed. 142699.doc 201017275 The touched position on board 2 will be darker than the position that is not touched. On the other hand, if there is more than a certain degree around the display panel 2 The invisible light reflected by the object to be irradiated from the invisible light emitting portion 22 is incident on the touch panel 2, so that the touched portion on the display panel 2 is less than the touched surface. The position is brighter. Considering the above situation, the display device 1 sets the detection method of the touch position of the display panel 2 according to the brightness value of the entire screen of the display panel 2. FIG. 3 shows that the touch position on the display device 1 is determined. First, the detection processing unit 4 detects the brightness of each pixel constituting the display panel 2 (step S1). Next, the detection processing unit 4 calculates the entire screen based on the detected brightness of each pixel. Brightness (step S2). At this time, for example, the total value of the respective luminances, the average value, and the like are set as the brightness of the entire surface. Further, the detection setting unit 8 determines whether or not the overall brightness of the screen exceeds a predetermined standard value (step S3). When the result of the determination in step S3 is "false" (N〇), the detection setting unit 8 sets the pixel whose brightness is darker than the screen brightness as the touch point (step S4). On the other hand, when the result of the determination in step S3 is "YES" (YES), the detection setting unit 8 sets the pixel whose brightness is brighter than the screen brightness as the touch point (step S5). According to the setting processing described above, the display device can correctly detect the touch position of the display panel 2 regardless of the surrounding redundancy. Further, the display device 1 does not collectively provide a detection method for the entire screen of the display panel 2, and may divide the entire screen into a plurality of areas, and set a detection method for each of the areas. In this case, the brightness of each area of the invisible light detected by the pixels included in the area such as 142699.doc 201017275 is calculated for each area. Then, the calculated luminance and the reference luminance are compared, and the detection method of the region is set based on the comparison result. Further, by applying a certain bias voltage according to the detected brightness, the detection sensitivity is adjusted, and the accuracy of the detection can be improved. Alternatively, the invisible light emitting portion 22 is used to change the illumination brightness of the invisible light to be irradiated, and the detection reference is changed, and the detection resistance with respect to the surrounding light can also be improved. (Application example of the user interface) The user who has indicated that the device 1 is not in use touches the display panel 2 with a special pen, which is created by reflecting the material of the invisible light by the pen tip. At this time, the display device 1 detects the touch position by performing the above-described detection processing. Further, by detecting a change in the touch position, processing can be performed based on the detection result. Therefore, the user can operate the display device 1 using a dedicated pen. The user is not limited to the use of the dedicated pen described above, and the display device can be operated by other types of operating devices. An example of this is shown in Figure 4. Fig. 4 is a view showing a display device in a state in which the dial-shaped operation device 1〇1 and the card-shaped operation device 1〇2 are placed on the top surface. On the screen of the display panel 2, the operating device 1 〇 1 and the operating device 〇 2 are arranged. The user operates by moving the H-pieces according to the surface condition of the surface portion of the device. Further, a multi-user interface can be realized by attaching a material that reflects invisible light to a fingertip glove or the like. Furthermore, it is also possible to adopt a method of including an invisible light reflection image printed on a card or the like including a barcode (including two-dimensional) or a hidden image technique, and can be passed through a fox or the like in which the image is embedded. Set the communication line to access websites or e-books. More specifically, a plurality of dial-shaped operating devices 101 may be placed on the screen of the display panel 2 for operation, or a plurality of card-shaped operating devices 102 may be placed on the screen for operation.
