Summary: | Display apparatuses are disclosed. In one arrangement, a display apparatus comprises a plurality of pixel units. Each pixel unit comprises: an optically switchable element; a heater operable to applyheating to the optically switchable element and thereby change an optical property of the optically switchable element; and a drive unit for driving the heater in response to a drive signal. The driveunit is provided within a first layer. The optically switchable elements and heaters of the plurality of pixel units are separated from the first layer by at least a portion of a second layer. An average thermal conductivity of the second layer is lower than an average thermal conductivity of the first layer.
公开了显示装置。在一种布置中,显示装置包括多个像素单元。每个像素单元包括:光学可切换元件;加热器,可操作用于将热施加至光学可切换元件,从而改变光学可切换元件的光学性质;和驱动单元,用于响应于驱动信号而对加热器进行驱动。驱动单元设置在第一层内。多个像素单元的光学可切换元件和加热器通过第二层的至少一部分与第一层分开。第二层的平均热导率低于第一层的平均热导率。 |
