Sensor-embedded display panel and electronic device

A sensor-embedded display panel, comprising:

• a display area configured to display a color and a non-display area excluding the display area and configured to not display any color,
• wherein the display area includes
• a first subpixel configured to display a first color and including a first light emitting element,
• a second subpixel configured to display a second color and including a second light emitting element, and
• a third subpixel configured to display a third color and including a third light emitting element,
• wherein the non-display area includes a light absorption sensor that is between at least two of the first subpixel, the second subpixel, or the third subpixel,
• wherein the first, second, and third light emitting elements include respective first, second, and third light emitting layers configured to emit light of an emission spectrum corresponding to the first, second, and third colors, respectively,
• wherein the light absorption sensor comprises a light absorbing layer comprising a p-type semiconductor and an n-type semiconductor forming a pn junction, and configured to absorb light reflected by a recognition target and convert the reflected light into an electrical signal,
• wherein respective sublimation temperatures of organic materials included in the first, second, and third light emitting layers and the n-type semiconductor are each less than or equal to about 390° C., respectively, wherein each sublimation temperature of each given organic material and the n-type semiconductor is a temperature at which a weight reduction of 10% relative to an initial weight of the given organic material and the n-type semiconductor occurs during thermogravimetric analysis under an ambient pressure of about 10 Pa or less, and
• wherein a difference in respective sublimation temperatures between the organic materials included in the first, second, and third light emitting layers and the n-type semiconductor is about 0° C. to about 150° C.
