Embodiment Construction

[0065] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that these embodiments are merely examples for realizing the present invention, and do not limit the technical scope of the present invention. Common elements in the figures are denoted by the same reference numerals.

[0066] Figure 1A and Figure 1B A structural example of a display device is schematically shown. Figure 1A is a top view of the display device 10, Figure 1B is along Figure 1A A cross-sectional view taken along the line A-A. Such as Figure 1B As shown, the display device 10 includes a display panel 101 and a front panel 103 stacked on the display panel 101 . exist Figure 1A and Figure 1B In an example, the display panel 101 and the front panel 103 have a rectangular shape. These panels can have different shapes. The display panel 101 may be of any type; for example, the display panel 101 may be a liquid crystal...

Abstract

The present invention relates to a display device, comprising: a display panel including a display area displaying a user image and a measurement area; a transparent front panel disposed on the front side of the display panel; an adhesive layer , the adhesive layer is disposed between the display panel and the front panel to avoid the first space and cover the display area, and bond the display panel and the front panel together; and a component in the first space, the component comprising a detector configured to detect a physical characteristic of the measurement region in the first space and a flexible printed circuit on which the detector is mounted, the A flexible printed circuit extends from the first space to an outside of a gap between the display panel and the front panel.

Description

technical field [0001] The invention relates to a display device. Background technique [0002] In recent years, demands for display quality of display devices have increased. For example, in the field of medical monitors, since changes in monitor brightness cause changes in grayscale display characteristics, the importance of diagnostic imaging is critical to the function (calibration) that continuously monitors monitor brightness with an optical sensor and performs feedback control based on it. Generate requirements (see eg WO2013 / 102997A). [0003] On the other hand, display devices having a transparent front panel on the front side of the display module are increasing; the transparent front panel may be an input interface part such as a touch panel, or provided for design purposes or for protecting the surface of the display panel. If there is an air layer between the surface of the display panel of the display module and the front panel, at the interface between the f...
