By the way, since the conventional vehicle information display apparatus as described in Patent Document 2 has a configuration in which a plurality of displays are made in one liquid crystal panel, there are the following problems.
When the display device is mounted on an instrument panel of a vehicle and a meter such as a speedometer is displayed as an image, an actual display area (meter or the like is displayed in the light emitting area of the liquid crystal panel). A circular display portion) and an area other than the actual display area that is not used for image display are formed, and an area other than the actual display area is not effectively used.

  The present invention has been made paying attention to such conventional problems, and its purpose is to enable effective use of an area not used for image display (unused part), and to improve versatility. It is an object of the present invention to provide a display panel, a display device, and a moving body display module that enable display with high luminance.

The display panel according to the present invention includes a light emitting area in which a plurality of pixels are arranged in a matrix and a non-light emitting area in which the pixels are not arranged, and displays an image by driving an electro-optical element of each pixel. The light emitting area includes an actual display area used for image display and an area other than the actual display area, and at least one light emission disposed in at least one of the area other than the actual display area and the non-light emitting area. The gist is to provide a body.

  According to this, since at least one light emitter is disposed in at least one of the non-light emitting area and the non-real light emitting area in the light emitting area, the area not used for image display (unused portion of the display panel) By effectively using the light emitter, it is possible to display a blinker, to turn on a lamp for notifying various warnings, and to display an indicator by the light emitter. For example, when it is mounted on a vehicle such as an automobile, various lamps can be turned on or blinked, or a display informing that the seat belt is not worn can be displayed by the light emitter. Further, since the light emitters may be arranged in an area not used for image display on the display panel, it is easy to change the display design, for example, the position and number of light emitters (for example, lamps), the display mode by the light emitters, and the like. A display panel with high versatility can be obtained. In addition, since a light emitter corresponding to the required luminance can be selected, it is possible to respond to a display request with high luminance. Therefore, an area not used for image display can be used effectively, and versatility can be improved and display with high luminance can be realized.

  Here, the “electro-optical element” means an element whose optical characteristics are changed by an electric action, and includes, for example, a liquid crystal, an organic EL element which is an electroluminescence element, and the like. The “non-light emitting area” is an area called a frame outside the light emitting area.

  The gist of the display panel is that the at least one sensor is a light emitting diode. According to this, various displays different from the actual display area, lighting of the lamp, and the like can be performed by effectively using the area other than the actual display area in the light emitting area or the non-light emitting area. For example, when a display panel is mounted on an instrument panel of a vehicle such as an automobile and a speedometer, a tachometer, or the like is displayed in an actual display area, an area other than the actual display area that is not used for image display is formed in the light emitting area. Therefore, various display units can be arranged by effectively using an area other than the actual display area.

  In addition, the light emitting diodes can blink the left and right direction indicating sections for blinker display, turn on or blink lamps that notify various warnings, and display various indicators. Further, in an active matrix drive type display panel in which the electro-optic elements of a plurality of pixels are driven in the same way by a common power source, it is difficult to control the peak luminance only at a certain part in the light emitting area. For this reason, when displaying the direction indicator and various indicators for the blinker display in addition to the image such as the speedometer in the light emitting area of the display panel, the display other than the image such as the speedometer has a limited brightness. Can only be displayed in a range. On the other hand, according to the present invention, since the light emitting diode that emits light with a necessary luminance need only be arranged in a region other than the actual display region of the display panel or in a non-light emitting area, display with high luminance is required. It is possible to easily cope with display of an indicator or the like, and to realize a highly versatile display panel.

  The gist of the display panel is that the at least one light emitter is an area color panel. According to this, it is possible to display a fixed display notifying various warnings, for example, a fixed image notifying that the seat belt is not worn, by the area color panel. This area color panel only needs to be arranged in an unused display area of the display panel, and it is not necessary to make it on the same substrate as the display panel. Therefore, a highly versatile display panel can also be realized in this respect.

The gist of the display panel is that the area color panel is an electroluminescence panel. Accordingly, a fixed display for notifying various warnings, for example, a fixed image for notifying that the seat belt is not worn, can be displayed by the area color panel constituted by the electroluminescence panel.

  In this display panel, the gist of the display panel is an electroluminescence panel in which an electroluminescence element is provided in each pixel as the electro-optic element. According to this, it is possible to effectively use an area other than the actual display area in the light emitting area that is not used for image display, and to realize an electroluminescence panel that is highly versatile and capable of displaying with high luminance. Can do.

  The display device according to the present invention is a display device using the display panel, and includes a panel cover attached to the panel surface of the display panel and provided with a first opening in a portion corresponding to the actual display area, In the panel cover, at least one second opening that guides light from the light emitting diode to the outside provided in a region including the region other than the actual display region and the non-light emitting area on the panel surface. The gist is that the light emitting diode is accommodated in the second opening.

  According to this, it is possible to effectively use a region that is not used for image display, and it is possible to realize a display device that is highly versatile and capable of displaying with high luminance. In addition, the light emitting diodes can blink the left and right direction indicating sections for blinker display, turn on or blink lamps that notify various warnings, and display various indicators. In addition, it is possible to easily cope with display of an indicator or the like that is required to display with high luminance, and it is possible to realize a highly versatile display device. Moreover, a light emitting diode can be arrange | positioned using a part of panel cover attached to the panel surface of a display panel.

  The display device according to the present invention is a display device using the display panel, and includes a panel cover attached to the panel surface of the display panel and provided with a first opening in a portion corresponding to the actual display area, The panel cover has at least one third opening that guides light from the area color panel provided in an area including an area other than the actual display area and the non-light emitting area on the panel surface. A gist is that the area color panel is accommodated in the third opening.

  According to this, it is possible to effectively use a region that is not used for image display, and it is possible to realize a display device that is highly versatile and capable of displaying with high luminance. The area color panel can display a fixed display for notifying various warnings, for example, a fixed image for notifying that the seat belt is not worn. In addition, a highly versatile display device can be realized. Moreover, an area color panel can be arrange | positioned using a part of panel cover attached to the panel surface of a display panel.

  The gist of the display module of the moving body according to the present invention is that a plurality of the display panels are arranged side by side and different images are displayed on the plurality of display panels. According to this, in a display module of a moving body that displays different images on a plurality of display panels, it is possible to effectively use an area other than the actual display area among the light emitting areas of each display panel.
