Device for touch-sending functions, display panel containing the same, and method for operating the same
The present disclosure provides a device for touch-sensing. The device includes a touch surface configured to receive a touch by an object; a measuring portion configured to measure a blood oxygen level of the object; and a control portion configured to calculate a level of pressing force corresponding to the blood oxygen level.
1. A device for touch-sensing functions, comprising:
a touch surface configured to receive a touch by an object;
an optical sensor; and
a control unit configured to:
determine a blood oxygen level of the object based on readings from the optical sensor;
determine one of a plurality of blood oxygen level ranges within which the blood oxygen level of the object falls;
determine one of a plurality of pressing force levels that corresponds to the one of the plurality of blood oxygen level ranges according to a mapping relationship between pressing force levels and blood oxygen level ranges;
determine one of a plurality of commands that corresponds to the one of the plurality of pressing force levels according to a mapping relationship between commands and pressing force levels; and
control the device for touch-sensing functions to take an action in accordance with the one of the plurality of commands.
2. The device according to claim 1 , further including a frame configured to package the control unit.
3. The device according to claim 2 , further including a display panel packaged by the frame.
4. The device according to claim 1 , wherein the optical sensor comprises: a light emitting device configured to emit light of a plurality of colors; and a receiver configured to measure the red light and the infrared light reflected by the object.
5. The device according to claim 4 , wherein the touch surface is substantially transparent to the plurality of colors.
6. The device according to claim 4 , wherein the light emitting device emits red light and infrared light.
7. A method for operating a device for touch-sensing functions, comprising:
receiving a touch motion on a portion of the device for touch-sensing functions by an object;
receiving a reading of light of a plurality of colors reflected by the object;
determining a blood oxygen level of the object based on the readings of a red light and an infrared light reflected by the object;
determining one of a plurality of blood oxygen level ranges within which the blood oxygen level of the object falls;
determining one of a plurality of pressing force levels that corresponds to the one of the plurality of blood oxygen level ranges according to a mapping relationship between pressing force levels and blood oxygen level ranges;
determining one of a plurality of commands that corresponds to the one of the plurality of pressing force levels according to a mapping relationship between commands and pressing force levels; and
controlling the device for touch-sensing functions to take an action in accordance with the one of the plurality of commands.
8. The method according to claim 7 , further comprising:
operating the device for touch-sensing functions by using the readings of the red light and the infrared light reflected by the object.
9. A display device, incorporating the device for touch-sensing functions according to claim 1 .
10. The display device according to claim 9 , wherein the touch surface of the device for touch-sensing functions is a part of a display surface of the display device.
11. The display device according to claim 9 , wherein the touch surface of the device for touch-sensing functions is not a part of a display surface of the display device.
12. The display device according to claim 9 , wherein a display surface of the display device has touch-sensing functions.
