A switchable backlight for a switchable privacy display apparatus comprises a collimated waveguide, first and second light sources and an optical turning film comprising elongate prismatic elements with facet orientations that pupillate the output of the waveguide in two orthogonal directions for each of first and second light sources. High luminance uniformity is achieved for a head-on user in privacy and public viewing modes and high uniformity of security factor is achieved for off-axis snoopers, with increased speed of privacy switch-on in privacy mode.

Discussed is a liquid crystal display device that can include a backlight unit, a switching unit disposed on an upper side of the backlight unit and including a first twisted nematic (TN) switching cell configured to change light transmittance for a first direction between a first mode and a second mode and a second twisted nematic (TN) switching cell disposed on an upper side of the first TN switching cell, and an image display layer disposed on an upper side of the switching unit. According to embodiments of the present disclosure, by providing a liquid crystal display device having a triple cell structure including two TN switching cells and one image cell, a light output for a first direction can be effectively blocked in a second mode in which partial viewing angle blocking is needed.

An operation device includes a housing arranged on a center cluster located diagonally in front of a driver seat and a passenger seat of a vehicle, a left-side operation unit and a right-side operation unit arranged on a right side and a left side, respectively, of a front surface of the housing to receive an operation, a left-side operation detection unit and a right-side operation detection unit to detect an operation performed on the left-side operation unit and the right-side operation unit, respectively, a substrate on which the left-side and right-side operation detection units are arranged, and an output unit that outputs a sound in response to a received operation and is arranged on the substrate so as to be located between the left-side operation detection unit and the right-side operation detection unit at a position to equalize distances from the driver seat and the passenger seat.

A maintenance system can be used with a self-driving vehicle. The maintenance system can include a vehicle management system configured to autonomously drive the vehicle to a destination chosen by a rider. The maintenance system can include a smoke detection system configured to detect smoke inside a cabin of the vehicle.

A processing method for a processing apparatus, the processing method causing a computer of the processing apparatus to execute steps comprising: detecting a position and a state of a passenger inside a vehicle on the basis of information indicating a state of space including seats of the vehicle, the information obtained from a sensor provided inside the vehicle, notifying an operator of the vehicle of the detected position and state of the passenger, and transmitting, upon detecting an operation, which is performed by the operator of the vehicle, for controlling a device near the detected position of the passenger, a control command corresponding to the operation to the device.

A device for controlling an interior lighting system of a vehicle to produce ambient lighting and/or reading lighting involves the interior lighting system having an array of a plurality of light sources. The device includes a control unit, by means of which the light sources of the array can be individually controlled in order to produce the ambient lighting and/or the reading lighting, and an input unit that can be connected to the control unit. The input unit has a touch-sensitive screen for inputting a current set of control information for the control unit. The control unit controls the light sources on the basis of the current set of control information. Furthermore, the input unit, on the basis of the current set of control information, displays associated ambient lighting and/or reading lighting for an illuminable region in the vehicle interior on the screen.

A method for setting a multi remote control in a vehicle includes: a communicator configured to perform wireless communication with a plurality of mobile communication terminals in the vehicle, a storage configured to store information related to the plurality of mobile communication terminals and remote control function setting information of a device in the vehicle, and a controller configured to distinguish between a mobile communication terminal located in a front seat and a mobile communication terminal located in a rear seat based on short-range communication connection strength of each of a plurality of mobile communication terminals inside the vehicle, the controller distributing each of a front seat remote control function and a rear seat remote control function to the distinguished front seat or rear seat mobile communication terminal.

Provided is an audio-video-navigation (AVN) monitor drive unit for a vehicle, which is configured to tilt an AVN monitor coupled to a crash pad in a direction toward a passenger seat. The AVN monitor drive unit includes a monitor assembly, a hinge bracket slidably positioned at a rear of the monitor assembly, and a tilting portion configured to connect the monitor assembly and the hinge bracket to each other and tilt the monitor assembly from the hinge bracket.

A seat having features of evaluating a physical state of a seated occupant, in which motivation to use the features is enhanced, is provided. A physical state sharable seat is proposed which includes: a seat body; a sensor (8) configured to acquire a measurement value specific to a physical state of an occupant seated on the seat body; and a controller (100) connected to the sensor and thereby allowed to acquire the measurement value from the sensor, and configured to be capable of communicating with other equipment. The controller (100) includes: an evaluation unit (121) configured to compute an evaluation value on the physical state, based on the measurement value; an evaluation value presentation unit (122) configured to present the evaluation value at a terminal to be used by the occupant; a shared data acquisition unit (161) configured to acquire an other-occupant evaluation value that is an evaluation value on a physical state of another person, acquired either by the evaluation unit or from another physical state sharable seat; and a shared data presentation unit (162) configured to present the other-occupant evaluation value at the terminal to be used by the occupant.
