  • Patent number: 12060939
    Abstract: A control apparatus for a vehicle that is provided with an electric parking device for causing a parking pawl to be meshed with a parking gear so as to lock rotation of a wheel of the vehicle. When a parking range is selected, a parking control is executed for moving the parking pawl to a parking position in which the parking pawl is meshed with the parking gear. When the parking control is to be executed, it is determined whether or not the electric parking device is in a ratcheting state in which the parking pawl is repelled by the parking gear without the parking pawl being meshed with the parking gear. When it is determined that the electric parking device is in the ratcheting state, the parking control is stopped to move the parking pawl to a non-parking position.

    Abstract: A display device having high light-extraction efficiency is provided. A low-power display device is provided. In a red or green pixel included in the display device, a light-emitting element, an optically functional layer, and a wavelength-conversion layer are stacked in this order. The light-emitting element emits blue light, the optically functional layer transmits the blue light and reflects red and green light, and the wavelength-conversion layer converts the blue light into red or green light. The blue light emitted by the light-emitting element passes through the optically functional layer and enters the wavelength-conversion layer, and red or green light is emitted to the outside. The red or green light emitted from the wavelength-conversion layer to the optically functional layer side is reflected by the optically functional layer and emitted to the outside, which improves light-extraction efficiency.

  • Publication number: 20230420614
    Abstract: A high-resolution, high-definition, or large display apparatus is provided. A metal mask is placed over an EL layer and film deposition is performed with the metal mask, whereby an island-shaped counter electrode is formed. Then, the EL layer is processed using the counter electrode as a hard mask. Alternatively, after an EL layer and a counter electrode are formed over an entire surface, processing using a metal mask is performed. An insulating layer that electrically insulates adjacent pixel electrodes from each other is positioned between adjacent light-emitting devices. A resist mask is formed over the insulating layer. A plurality of EL layers and a plurality of counter electrodes overlapping each other over the insulating layer are partly removed using the resist mask, whereby part of the insulating layer is exposed. Thus, the adjacent light-emitting devices are electrically insulated from each other over the insulating layer.
