More Information
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 apply heating 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 drive unit 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.
