Abstract: A pixel structure for a display device is provided. The pixel structure utilizes light entering from the ambient environment of the display as a light source. The pixel structure comprises a first substrate, a light obstructing layer, an active element and an adjustable light shielding layer. The light obstructing layer is disposed on the first substrate and has a transparent area and an opaque area. The active element is disposed on the opaque area of the light obstructing layer and has a first state and a second state. The adjustable light shielding layer is disposed on the light obstructing layer and the active element. When the active element is in the first state, the adjustable light shielding layer is adapted to cover the transparent area to shield the light from emitting out from the first substrate. When the active element is in the second state, the adjustable light shielding layer is driven to uncover the transparent area so that the light is adapted to emit out from the transparent area and the first substrate.

Abstract translation: 提供了一种用于显示装置的像素结构。 像素结构使用从显示器的周围环境进入的光作为光源。 像素结构包括第一基板，遮光层，有源元件和可调节遮光层。 遮光层设置在第一基板上，具有透明区域和不透明区域。 有源元件设置在遮光层的不透明区域上，具有第一状态和第二状态。 可调节遮光层设置在遮光层和有源元件上。 当有源元件处于第一状态时，可调节遮光层适于覆盖透明区域以遮蔽光从第一基板发出。 当有源元件处于第二状态时，可调节遮光层被驱动以露出透明区域，使得光适于从透明区域和第一基板发出。
