Description
図1は、本発明の実施形態に係る発光装置1の構成を示す斜視図である。発光装置1は、例えばヘッドマウントディスプレイにおいて画像を表示するマイクロディスプレイである。
(3n)列に対応する容量41の一方の電極は信号線18(3n)に接続されており、(3n)列に対応する容量41の他方の電極は給電線64に接続される。同様に、(3n−1)列に対応する容量41の一方の電極は信号線18(3n−1)に接続されており、(3n−2)列に対応する容量41の一方の電極は信号線18(3n−2)に接続される。(3n−1)列に対応する容量41の他方の電極、および(3n−2)列に対応する容量41の他方の電極は、給電線64に接続される。給電線64には、固定電位である電位VSSが供給される。ここで、電位VSSは、論理信号である走査信号や制御信号のLレベルに相当するものであってもよい。
n番目のグループにおいて左端列である(3n−2)列に設けられたトランスミッションゲート34は、制御信号Sel(1)がHレベルであるとき(制御信号/Sel(1)がLレベルであるとき)にオン(導通)する。同様に、n番目のグループにおいて中央列である(3n−1)列に設けられたトランスミッションゲート34は、制御信号Sel(2)がHレベルであるとき(制御信号/Sel(2)がLレベルであるとき)にオンし、n番目のグループにおいて右端列である(3n)列に設けられたトランスミッションゲート34は、制御信号Sel(3)がHレベルであるとき、即ち、制御信号/Sel(3)がLレベルであるときにオンする。
以上が本発明の一実施形態の説明であるが、この実施形態に以下の変形を加えてもよい。
(1)前述の実施形態では、データ線14(3n)が設けられる第2配線層L02を、給電線16(3n)および第1配線15(3n)が設けられる第1配線層L01とは別箇に設けた。しかし、図9に示すように、第2配線層L02および第2金属層M02を省略し、第1配線層L01に給電線16(3n)、データ線14(3n)および第1配線15(3n)を設けてもよい。
前述の実施形態に係る発光装置は、各種の電子機器に適用することができ、特に2K2K以上の高精細な画像の表示を要求され、かつ小型であることを要求される電子機器に好適である。以下、本発明に係る電子機器について説明する。
