摘要

Various embodiments illustrated herein disclose a method for operating a display screen in an electronic device. The method includes detecting an event on the display screen of the electronic device based on an input received from a plurality of sensors in the display screen. Further, the method includes identifying one or more first areas on the display screen based on the detected event. Furthermore, the method includes altering one or more electric currents supplied to one or more photo transmitters associated with the one or more identified first areas of the display screen, wherein the one or more photo transmitters is configured to generate heat in the one or more identified first areas.

說明書

In some examples, the moisture detection unit 412 of the display screen 110 may be configured to utilize the display screen usage pattern to identify a set of third areas from the one or more third areas which may regularly receive touch input from the operator 108. Because the set of third areas may regularly receive the touch input, the controller 402 may instruct the first photo transceiver interface unit 410 to proactively heat the set of third areas so that moisture does not get accumulated in the set of third areas. The prediction of the set of third areas is further described in conjunction with FIG. 17.

In some example embodiments, the scope of the disclosure is not limited to altering the electric current supplied to the one or more photo transmitters every time the touch input is received on the display screen 110. Additionally or alternatively, the method described in the flowchart 1400 may be performed based on the current temperature of the ambient environment around the display screen 110. Such an implementation is described in conjunction with FIG. 15.

FIG. 15 illustrates a flowchart 1500 of another method for operating the display screen 110 based on detection of the event of reception of the touch input on the display screen 110 while the temperature of the ambient environment satisfies (e.g. is less than) the temperature threshold, according to one or more embodiments described herein.
