A watch dial having an organic light-emitting diode display. The display includes an anode, a structured layer of coloured resin, which is preferably photosensitive, in contact with the anode. The display further includes an organic layer stack in contact with the anode and with the structured coloured resin layer. At least one of the organic layers is a light-emitting layer. The display also includes a cathode in contact with the organic layer stack. Also, a watch including the dial and a method for manufacturing the dial.

A digital display device including, from top to bottom, a first red filter, a transflective liquid crystal display cell, a second red filter and an emissive display cell, the transflective liquid crystal display cell displaying information using at least one first seven-segment digit and the emissive display cell providing a plurality of juxtaposed light points which are arranged so as to provide a display formed by at least one second seven-segment digit.

An electronic display may include an active area having a first pixel formed in the active area, where the first pixel emits light in response to image data. The electronic display may also include a controller to transmit the image data to the first pixel. The first pixel may include an organic light-emitting diode that emits the light in response to the image data, memory to digitally store the image data received from the controller, and driver circuitry to receive the image data from the memory. The driver circuitry may cause the organic light-emitting diode to emit the light in response to the image data.

A display device and a terminal device are disclosed. The display device includes a main body and a cover body rotatably connected to the main body, the main body includes a first display screen on a side, close to the cover body, of the main body, the cover body is provided with an accommodating cavity penetrating through the cover body in a direction perpendicular to the first display screen, the cover body includes a second display screen in the accommodating cavity, the second display screen is stacked on the first display screen in the direction perpendicular to the first display screen, and the second display screen is a transparent display screen.

An electronic device such as a wristwatch device or other device may have a display. The display may be used to continuously display information such as watch face information. A watch face image on the display may contain watch face elements such as watch face hands, watch face indices, and complications. To reduce burn-in risk for watch face elements, control circuitry in the electronic device may impose burn-in constraints on attributes of the watch face elements such as peak luminance constraints, dwell time constraints, color constraints, constraints on the shape of each element, and constraints on element style. These constraints may help avoid situations in which static elements such as watch face indices create more burn-in than dynamic elements such as watch face hands.

A display module and system applications including a display module are described. The display module may include a display substrate including a front surface, a back surface, and a display area on the front surface. A plurality of interconnects extend through the display substrate from the front surface to the back surface. An array of light emitting diodes (LEDs) are in the display area and electrically connected with the plurality of interconnects, and one or more driver circuits are on the back surface of the display substrate. Exemplary system applications include wearable, rollable, and foldable displays.
