Abstract
Description
多くのスマートフォンは、光学近接センサを用いてディスプレイをいつオンまたはオフにすべきかを判断する。これは典型的に、たとえばスマートフォンがユーザのポケットに入っているときにバッテリ電力を節約するため、または電話がかかってきたときに不要なスクリーン上の表示ボタンを選択しないようにするためである。これは、タブレットおよびラップトップコンピュータといったディスプレイを有する他のコンピュータデバイスの、当該デバイスが閉じられたまたはそうでなければ覆われたときにディスプレイをオフにすることが望ましい場合も同様であり得る。光学近接感知は典型的に、近赤外(NIR)光を放出し、反射された任意の光エネルギを測定することに依存する。一定のしきい値を超える反射は、ディスプレイが覆われている可能性が高いことを示す。
本発明の第1の局面によれば、ディスプレイを有するコンピュータデバイスの光学近接センサを動作させる方法が提供され、上記光学近接センサは上記ディスプレイの下方にまたはそうでなければ上記ディスプレイに隣接して位置している。上記方法は、ディスプレイドライバから垂直同期信号を得ることと、上記光学近接センサの光エミッタの周期的な照射を上記垂直同期信号に同期させることとを備える。
上記光学近接センサは、赤外光学近接センサ、たとえば近赤外光学近接センサであってもよい。
上記光学近接センサは、赤外光学近接センサ、たとえば近赤外光学近接センサであってもよい。
OLEDディスプレイのようなディスプレイの下方にNIR近接センサを用いることによって引き起こされる問題については上述した。以下に論じるソリューションは、表示画素の動作状態に対して最適化された時点でのみ近接センサを照射することによって歪みを低減することができるという認識から生じている。
