Display, electronic device having the display, and method of estimating bio-information using the electronic device

An electronic device comprising:

• a display having an array of unit pixels that each respectively include a light source pixel and a detector pixel, and configured to operate in a first mode for displaying an image, a second mode for acquiring an optical signal, and a third mode for displaying the image and acquiring the optical signal;
• and
• a processor configured to:
• determine whether the display is to operate in the first mode, the second mode, or the third mode;
• and
• control the display to operate in the first mode, the second mode, or the third mode;
• wherein the display comprises a converter configured to be selectively activated based on the display operating in the second mode or the third mode, receive an optical signal from detector pixels of the display, and convert the optical signal into a digital signal,
• wherein the converter comprises a plurality of analog-digital converters (ADCs), each connected to one or more detector pixels of the detector pixels of the array of unit pixels, and at least a portion of inputs of the detector pixels of the array of unit pixels are integrated to be connected to a detector driver.

An electronic device, comprising:

• and
• a processor configured to:
• based on receiving a request for estimating bio-information, control the display to operate in the second mode or the third mode to acquire a first optical signal from an object;
• and
• estimate bio-information based on the acquired first optical signal,
• wherein the display comprises:
• a display portion formed of the array of unit pixels;
• a control driver including a light source driver and a data driver which are respectively connected to each light source pixel, and a detector driver which is connected to each detector pixel;
• a controller configured to control the control driver to operate the display portion in the first mode, the second mode, and the third mode;
• and
• a converter configured to be selectively activated by the controller based on the display portion operating in the second mode or the third mode, receive an optical signal from detector pixels of the display portion, and convert the optical signal into a digital signal,
• wherein the converter comprises an analog-digital converter (ADC) connected to outputs of the detector pixels, and at least a portion of inputs of the detector pixels are connected to the detector driver independently of another portion of the inputs of the detector pixels.
