A remote controller is provided. The remote controller includes a transmitter; a microphone configured to receive an audio signal output from an audio output apparatus; a communicator comprising communication circuitry configured to perform communication with a display apparatus connected to the audio output apparatus and to transmit the audio signal received through the microphone to the display apparatus; and a processor configured to control the transmitter to transmit to the audio output apparatus a signal for controlling a power of the audio output apparatus based on information indicating whether there is a test tone in an audio signal received by the microphone and received from the display apparatus.

There is provided a display apparatus including a holding member disposed between a peripheral part of an optical sheet and a peripheral part of a diffusion plate. The holding member has a first end portion contacting the peripheral part of a rear surface of the optical sheet and a second end portion contacting the peripheral part of the first surface of the diffusion plate. The holding member has a first holding projection for holding the diffusion plate. The first holding projection protrudes from the second end portion along the first surface of the diffusion plate.

A display device including at least one speaker; a moveable display configured to be moved from a first position to a second position, wherein the display has a first spatial physical relationship with the at least one speaker at the first position and has a second spatial physical relationship with the at least one speaker at the second position; and a processor configured to control the at least one speaker and the display. In addition, the processor is configured to output audio from the at least one speaker, when the display is in the first position, and when receiving an information signal indicating the display has been moved to the second position from the first position, change the output of the audio from the at least one speaker based on the second spatial physical relationship.

A support member for a wearable device includes first and second contact portions coming into contact with a temporal region of a head, a frame portion interposed along a frontal region of the head between the first and second contact portions, and first and second connection portions respectively connecting the first and second contact portions and the frame portion to each other. In a top view, in the first connection portion, a first extension portion extending from the first contact portion and a first frame extension portion are branched ahead of an ear from the frame portion, and in the second connection portion, a second extension portion extending from the second contact portion and a second frame extension portion are branched ahead of the other ear from the frame portion. At least one of the first and second frame extension portions includes a support portion supporting a wearable device.

An electronic device such as a set top box is provided having a vertical chassis wall having an aperture; a horizontal circuit board that extends toward the vertical chassis wall; F-connector connected to the horizontal circuit board, either under or over the board, and extending out of the a vertical chassis wall through the aperture; and inner shield, which can generally be used to contain/shield the RF circuit components mounted on the PCB, on the interior side of the vertical chassis wall and connected to the F-connector on or under the horizontal circuit board, wherein the inner shield comprises a series of vertical peripheral walls that surround components (either under or over the board); and a shield cover that covers the inner shield, the shield cover comprises a top portion that runs along or extends horizontally and side portions that extend from the periphery of the top portion and downward to overlap a part of the shield wall. The side portions contact the exterior side of the shield walls or are substantially close to the exterior side to ensure no gap therebetween or such a minimal spacing to ensure direct path for electromagnetic interference.

An adhesive-free frameless display device comprises a backplane, an optical element secured to a surface of the backplane, a display panel secured to a side of the optical element away from the backplane, and a fixing assembly. The fixing assembly comprises a middle frame, a combining member removably secured to the middle frame, and a fixing member removably secured to the middle frame. The fixing member fixes the backplane, the display panel, and the combining member together. An electronic device using the frameless display device is also provided.

A display apparatus includes a frame, an image display apparatus attached to the frame, and a distortion correction apparatus. The image display apparatus includes an image forming apparatus and an optical system configured to guide an image from the image forming apparatus to a pupil of an observer. When it is assumed that a direction, which corresponds to a first direction of the image, of the image forming apparatus is an X-direction and a direction, which corresponds to a second direction of the image which direction is different from the first direction, of the image forming apparatus is a Y-direction, the image forming apparatus is curved in the X-direction and/or in the Y-direction. The distortion correction apparatus corrects an input image signal to correct a distortion of an image to be observed.

A head-mounted display includes a casing having a first wall and a second wall opposing to each other in a first direction, an image light generator arranged inside the casing and configured to emit image light in a second direction perpendicular to the first direction, and a reflective member having a reflective surface being parallel to the first direction. The reflective surface is configured to reflect the image light emitted from the image light generator to one side in a third direction which intersects with both the first direction and the second direction. The first wall has a protruding portion formed to extend over both sides, in the second direction, of the reflective surface. A surface area of a portion of the second wall overlapping the reflective member is smaller than a surface area of a portion of the first wall overlapping the reflective member in the first direction.

A vehicle instrument device includes: a display device accommodated in the vehicle instrument device; a display control circuit board which controls an operation of the display device and which is attached to a rear surface of the display device; and an instrument control circuit board which controls display except for the display device and which is formed as a separate member from the display control circuit. The display device, which is integrated with the display control circuit board to serve as a display unit, is accommodated in the vehicle instrument device together with the instrument control circuit board.
