The substrate includes: a first substrate; a conductive layer located on the first substrate; a second substrate located on the conductive layer; and a light source groove formed in a portion of the second substrate to permit a portion of the conductive layer to be exposed therethrough. The light source is disposed in the light source groove and is electrically connected to the conductive layer.

Display device

A display device is disclosed. The display device of the present disclosure comprises: a display panel; a frame positioned behind the display panel; a first light source positioned between the display panel and the frame and providing light to the display panel; a second light source adjacent to and spaced apart from the first light source; a substrate on which the first light source and the second light source are mounted and which is positioned in front of the frame; a first light guide plate positioned on the substrate and the first light source; and a second light guide plate positioned on the substrate and the second light source and spaced apart from the first light guide plate.

A memory device includes a memory module and a BIST logic circuit. The BIST logic circuit includes; a pattern generator configured to generate first main data including a first portion, an error correction code (ECC) encoder configured to generate first parity data based on the first main data, and a parity control circuit configured to generate mask data based on the first parity data and the first main data, and generate first substituted parity data based on the mask data and the first parity data, wherein a pattern of the first substituted parity data is the same as a pattern of the first portion of the first main data.

Built-in-self-test logic, memory device with same, and memory module testing method

A security circuit includes a decoder configured to receive input data and output a decoding signal in response to the input data, a first encoder configured to output one of first phenotypes corresponding to any one among integers in N-decimal (N is a natural number of 1 or more) as a first encoding value in response to the decoding signal, a second encoder configured to output one of second phenotypes corresponding to any one among integers in N-decimal as a second encoding value in response to the decoding signal, and a gate module circuit configured to generate output data by performing a logic operation on the first encoding value and the second encoding value.

Security circuit including dual encoder and endecryptor including the security circuit

Approaches presented herein enable displaying a virtual image in a real-world or virtual-world environment. More specifically, a virtual image is transmitted, via a virtual image projection component, through a substantially transparent medium onto a set of pinpoint mirrors in contact with the medium. The virtual image is transmitted, via the set of pinpoint mirrors, through the medium onto a set of optical elements that widens a field of view of the virtual image. A view of the virtual image transposed on a real-world or a virtual reality image is provided, via the set of optical elements, to a user looking through the medium. The light forming the virtual image is perceived by the human eye, but, because each pinpoint mirror of the set is smaller than the pupil of the human eye, none of the set of pinpoint mirrors is perceivable by the human eye due to their size.
