In an embodiment of the invention, a mode automatic switching display is provided for detecting whether a shelter is approached by a proximity sensor disposed on the housing. a proximity sensor, such as an optical proximity sensor, having a transmitter and At the receiving end, when there is a shield in front of the display to block the optical signal emitted by the transmitting end, the receiving end can receive the reflected optical signal, thereby achieving the purpose of detecting the shielding. In addition, when the proximity sensor detects that there is a shelter at a close distance and the distance is within a predetermined threshold, the display mode of the display is automatically switched. For example, when the medical staff diagnoses the X-ray film, without manually pressing the button and operating the OSD menu, the display can be automatically switched to the special display mode (such as the background light box mode) by simply placing the X-ray film close to the display and obscuring the proximity sensor. ), for medical personnel to diagnose X-rays using the background light source provided by the display at hand, thus eliminating the need for a traditional X-ray light box. After the medical staff has diagnosed the X-ray, simply remove the X-ray from the display and away from the proximity sensor, the display will automatically switch to the normal display mode (such as data display mode) for the general staff to use the display. Display pictures, text, images, and more.

The proximity sensor may also be a capacitive proximity sensor. When the capacitance sensing signal is detected to be greater than a predetermined capacitance threshold, indicating that the shielding is close to the display, the display can automatically switch to a special display mode (eg, background). Lightbox mode). In addition, the proximity sensor may also use an image proximity sensor or other type of sensor to detect the distance of the shield, which is not limited by the present invention.

The embodiments are described in detail below, and the embodiments are only intended to be illustrative and not intended to limit the scope of the invention.

Referring to FIGS. 1 and 2, respectively, a schematic diagram of a display 100 for automatically switching modes according to an embodiment of the present invention is shown, wherein the display 100 of FIG. 1 is an upright display, and the display 100 of FIG. 2 is a horizontal display. User can The posture of the display 100 is adjusted according to the use requirements. For medical or advertising purposes, the display 100 is often placed in an upright display for use as an X-ray light box or an advertising light box.

The display 100 includes a housing 110, a display panel 115, a adjuster 118, and a plurality of proximity sensors 120. The housing 110 has a display window 111, and the display panel 115 is disposed in the display window 111. In addition, the housing 110 may also have a frame 112, but not limited thereto, the frame 112 may surround the display window 111. When the frame 112 is mounted around the display panel 115, the proximity sensors 120 may be disposed on the frame 112. However, when the display panel 115 is not provided with the frame 112 (for example, no frame or The proximity sensor 120 can be disposed on the side of the display panel 115 in an external manner, which is equivalent to being disposed on the frame 112 of the display 100. The present invention does not limit this. In addition, the adjuster 118 is, for example, an electronic adjuster 118 that is connected to the display panel 115 for switching the display mode of the display panel 115. The adjuster 118 can be disposed on the frame 112 or directly disposed on the display panel 115. The adjuster 118 can adjust different parameters of the display panel 115, such as brightness values, color temperature, contrast, and color saturation, to present different display modes.

In addition, the proximity sensors 120 are configured to detect whether a mask 10 (eg, a translucent X-ray film) is adjacent to the proximity sensors 120 and determine between the shield 10 and the proximity sensors 120. Whether the distance is less than a threshold for the adjuster 118 to switch the display panel 115 to a corresponding display mode. Referring to Figures 1 and 2, the number of proximity sensors 120 is, for example, three or three. Up, but not limited to this. When the proximity sensor 120 determines that the distance between the shield 10 and the proximity sensors 120 is less than a threshold, the adjuster 118 switches the display panel 115 to a special display mode (eg, the background light box mode). When the proximity sensors 120 do not detect that a shield 10 is adjacent to the proximity sensors 120, the adjuster 118 switches the display panel 115 to a normal display mode (eg, a data display mode).

The above distance threshold can be set to less than 0.5 mm, or the user can customize a preferred distance threshold. For example, the user can finely adjust according to the light transmittance of the shielding 10 or the detection range of the proximity sensor 120, or directly correct the distance threshold according to the physical object to meet the specification.

In an embodiment, the data display mode has, for example, a first brightness value, and the backlight box mode has, for example, a second brightness value. In order to meet the actual use requirements, the second brightness value is preferably greater than or equal to 300 nits and greater than the first brightness value to cause the backlight box mode to have a higher brightness value. That is to say, in the background light box mode, the adjuster 118 can adjust the brightness value of the display panel 115 to meet the requirements of the conventional X-ray light box brightness of 300 nits.

Referring to FIGS. 1 and 2, the housing 112 includes a first frame S1, a second frame S2, a third frame S3, and a fourth frame S4. The first frame S1 is opposite to the third frame S3, and the second frame is opposite. S2 is opposite to the fourth frame S4. The proximity sensors 120 are respectively disposed on the first frame S1, the second frame S2, and the third frame S3. When at least two of the proximity sensors 120 are simultaneously shielded by the shielding 10 and the shielding 10 is shielded by at least two The distance between the proximity sensors 120 is predetermined When within the critical value, the adjuster 118 switches to the background light box mode to increase the brightness value or color temperature value of the display panel 115. In addition, another proximity sensor (not shown) is disposed on the fourth frame S4.

Next, please refer to FIG. 3 and FIG. 4 , which are schematic diagrams showing that the proximity sensors 120 are respectively disposed on the first frame S1 and the second frame S2 , or are respectively disposed on the first frame S1 and the third frame S3 . The invention does not limit that only one proximity sensor 120 can be disposed for each frame, and two proximity sensors 120 can also be disposed. Taking the quadrilateral frame as an example, the first frame S1 and the third frame S3 are longer, and the second frame S2 and the fourth frame S4 are shorter, and the plurality of proximity sensors 120 can be disposed on the longer frame, but the present invention Not limited to this.

In an embodiment, at least two of the proximity sensors 120 are respectively disposed on one of the first frame S1 and the third frame S3 and one of the second frame S2 and the fourth frame S4. In another embodiment, at least two of the proximity sensors 120 are respectively disposed on the first frame S1 and the third frame S3, or respectively disposed on the second frame S2 and the fourth frame S4. In another embodiment, at least three of the proximity sensors 120 are respectively disposed on at least three of the first frame S1, the second frame S2, the third frame S3, and the fourth frame S4.

The present invention does not limit which two of the proximity sensors 120 are simultaneously shielded by the shield 10, as long as two or more proximity sensors 120 are simultaneously shielded. For example, the two proximity sensors 120 respectively located at the first frame S1 and the second frame S2 are simultaneously shielded, or the two proximity sensors 120 respectively located at the first frame S1 and the third frame S3 are simultaneously shielded, or Located in the second border S2 and the two proximity sensors 120 of the third frame S3 are simultaneously shielded, or the two proximity sensors 120 respectively located at the second frame S2 and the fourth frame S4 are simultaneously shielded. As long as any two proximity sensors 120 on any two of the four bezels are simultaneously obscured, it is not limited that all of the proximity sensors 120 are shielded to initiate automatic mode switching.

In an embodiment, when the posture of the display 100 is changed, the adjuster 118 may first determine the posture of the current screen as an upright display by a g-sensor or a gyroscope (see FIG. 1).
