(See Patent Document 2). In such a vehicle information display device, one liquid crystal panel is used as a display panel.
JP 2001-260707 A JP 2004-291731 A

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 used for actual display 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 are formed, and the light emitting area is not effectively used.

  The present invention has been made paying attention to such a conventional problem, and its object is to provide a display panel, a display device, and a display module which are intended to effectively use an area not used for actual display. There is to do.

  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 sensor disposed in at least one of the area other than the actual display area and the non-light emitting area. It is a summary to provide.

  According to this, since at least one sensor is arranged in at least one of the area other than the actual display area and the non-light emitting area, an area that is not used for actual display can be used effectively. 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 gist of this display panel is that an illuminance sensor for detecting the illuminance of external light is disposed in the non-light emitting area as the at least one sensor.
According to this, the illuminance of light actually hitting the display panel can be accurately detected by the illuminance sensor arranged in the non-light emitting area. Thereby, the control etc. which change the brightness of a panel according to external light or the brightness of a vehicle interior can be performed using the signal detected with the illumination intensity sensor.

  The gist of the display panel is that a temperature sensor for detecting the temperature of the panel as the at least one sensor is disposed in a region including a region other than the actual display region and the non-light emitting area.

  According to this, the temperature of the display panel can be accurately detected by the temperature sensor disposed in the area including the area other than the actual display area and the non-light emitting area. Thereby, using the signal detected by the temperature sensor, it is possible to perform control such as changing the color balance of RGB (red, green, blue) or changing the display design according to the panel temperature. For example, when the display panel is an organic EL panel and a meter or the like is displayed on the organic EL panel, when the panel temperature is high, control is performed so that the heat-sensitive organic EL element does not emit light as much as possible. It is possible to control the background color such as the scale and the scale from a heat-sensitive color to a heat-resistant color. By such control, it is possible to suppress the deterioration of the light emission lifetime of the organic EL element that is weak against heat. Here, the heat-sensitive organic EL element means an element whose luminance deterioration is significantly accelerated by applying heat.

  In this display panel, the display panel is an electroluminescence panel in which an electroluminescence element is provided in each pixel as the electro-optic element, and a luminance detection that detects a light emission luminance of the electroluminescence element as the at least one sensor. The gist is that the sensor is arranged in a region other than the actual display region.

  According to this, since the light emission luminance of the electroluminescence element can be detected by the luminance detection sensor arranged in a region other than the actual display region, what is the light emission luminance of the electroluminescence element after being used for a certain period of time? Can know. In addition, since the luminance detection sensor is arranged in an area other than the actual display area in the light emitting area, it detects the luminance of the light actually emitted by the electroluminescence elements of the pixels in the area other than the actual display area. Can be monitored. For this reason, unlike the conventional electroluminescence panel, it is not necessary to provide a dummy pixel for detecting the light emission luminance of the electroluminescence element. Incidentally, since the conventional electroluminescence panel cannot detect the light emission luminance of the pixels in the light emitting area, a dummy pixel is provided outside the active area, and the light emission luminance of the dummy pixel is monitored.

  In the display device using the display panel according to the present invention, the display device includes a panel cover attached to the panel surface of the display panel and having an opening provided in a portion corresponding to the actual display area. Are provided with an external light introducing hole for introducing external light into an area including the area other than the actual display area and the non-light emitting area on the panel surface, and the illuminance sensor is provided on the panel surface. The gist is that the external light is disposed at a position where the external light is introduced from the external light introduction hole and is accommodated in the external light introduction hole.

  According to this, it is possible to realize a display device that effectively uses an area other than the actual display area that is not used for actual display in the light emitting area. Moreover, an illuminance sensor can be arrange | positioned using a part of panel cover attached to the panel surface of a display panel.

  In the display device using the display panel according to the present invention, the temperature sensor includes a panel cover attached to a panel surface of the display panel and having an opening provided in a portion corresponding to the actual display region. Is arranged in an area including the area other than the actual display area on the panel surface and the non-light emitting area, and is accommodated in a temperature sensor accommodating recess provided in the panel cover. .

  According to this, it is possible to realize a display device that effectively uses an area other than the actual display area that is not used for actual display in the light emitting area. Moreover, a temperature sensor can be arrange | positioned using a part of panel cover attached to the panel surface of a display panel.

  In the display device using the display panel, the display device according to the present invention includes a panel cover attached to a panel surface of the display panel and provided with an opening in a portion corresponding to the actual display region, and the luminance detection The sensor is located at a position for receiving light emitted by the electroluminescence element of a pixel in a region other than the actual display region among the plurality of pixels, and is provided in a luminance detection sensor housing recess provided in the panel cover. The gist is that it is contained.

In addition, the luminance detection sensor can be arranged by using a part of the panel cover attached to the panel surface of the display panel.

The gist of the display module 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.
