DISPLAY DEVICE AND BLOOD PRESSURE MEASUREMENT METHOD USING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17989543 titled 'DISPLAY DEVICE AND BLOOD PRESSURE MEASUREMENT METHOD USING THE SAME
Simplified Explanation
The patent application describes a method for measuring blood pressure using a display device.
- The method involves using a display panel with different types of sub-pixels, a pressure sensor, and a photo-sensor.
- The first step is to generate a pulse wave signal based on the light emitted by the first sub-pixels and sensed by the photo-sensor.
- Similarly, a second pulse wave signal is generated based on the light emitted by the second sub-pixels and sensed by the photo-sensor.
- The next step is to generate a third pulse wave signal by removing noise from the second pulse wave signal using the first pulse wave signal, the second pulse wave signal, and the maximum value of the first pulse wave signal.
- Finally, blood pressure information is calculated based on the third pulse wave signal and the pressure measurement value from the pressure sensor, and this information is displayed on the display panel.
Original Abstract Submitted
A blood pressure measurement method using a display device including: a display panel including first sub-pixels and second sub-pixels; a pressure sensor to sense a pressure applied from the outside; and a photo-sensor to sense light, includes: generating a first pulse wave signal according to light emitted by the first sub-pixels and sensed by the photo-sensor; generating a second pulse wave signal according to light emitted by the second sub-pixels and sensed by the photo-sensor; generating a third pulse wave signal by removing noise from the second pulse wave signal based on the first pulse wave signal, the second pulse wave signal, and a maximum value of the first pulse wave signal; and calculating blood pressure information based on the third pulse wave signal and a pressure measurement value sensed by the pressure sensor. The blood pressure information is displayed on the display panel.
