Abstract: A semiconductor composite layer can include a source electrode and a drain electrode individually comprising both a carrier mobility contributor and an amorphous phase stabilizer. The semiconductor composite layer can further include a semiconductive portion disposed between the source electrode and the drain electrode wherein the semiconductive portion comprises the carrier mobility contributor and the amorphous phase stabilizer, the semiconductivity controller comprising oxygen and an element having an electrode potential that is lower than that of both the carrier mobility contributor and the amorphous phase stabilizer.

Abstract: The present disclosure is drawn to privacy films for electronic displays. In one example, a privacy film for an electronic display can include a louver film. The louver film can include: a plurality of high refractive index slats with a refractive index of about 1.5 to about 3 and having a trapezoidal cross section narrowing toward a viewer side of the louver film; and a plurality of low refractive index slats between the high refractive index slats, having a refractive index less than the refractive index of the high refractive index slats by about 0.1 to about 2. An electrophoretic ink can be optically associated with the low refractive index slats, including opaque particles that are electrically mobile to cause modification of light transmission therethrough. A first and second transparent electrode film can be on a viewer side and a rear side of the electrophoretic ink, respectively.

Abstract: In some examples, a method includes receiving, by a timing controller of a display device, an indication from an embedded controller of a computing device during a computing device startup procedure. In some examples, the method includes determining, by the timing controller, whether to access display image memory or computing device image memory based on the indication. In some examples, the method includes accessing, by the display device, the computing device image memory in response to determining to access the computing device image memory. In some examples, the method includes causing the display device to display an image from the computing device image memory in response to determining to access the computing device image memory.

Abstract: An electronic device comprises circuitry to generate and authenticate a first write protect (WP) signal; a controller to write data to a memory, the controller to generate a second WP signal; and a logic gate coupled to the circuitry and the controller. The logic gate is to receive the first and second WP signals; generate a third WP signal based on the first and second WP signals; and assert the third WP signal to the memory to control a write enable state of the memory.
