Abstract: A display apparatus includes: a display unit for displaying images, a backlight unit disposed behind the display unit for illuminating the display unit, an inverter unit for electrically controlling the backlight unit, a controller unit for controlling the inverter unit and the display unit, and a power supply unit having an exothermic heat distribution for supplying electricity to the inverter unit and the controller unit. The inverter unit and controller unit are disposed behind the backlight unit. The power supply unit is disposed on a side of the display unit, backlight unit, inverter unit and controller unit. The display unit, backlight unit, inverter unit, controller unit and power supply unit are disposed in a common housing. The inverter unit and said controller unit are arranged behind the backlight unit. An insulating member is further disposed between the power supply unit and the display unit at a position corresponding to a region of relatively large exothermic heat of the power supply unit so that the insulating member is disposed at a diagonal position with respect to the inverter unit. The display apparatus may be supported by a support structure including vertically tilting and laterally turning mechanisms.

Abstract: A liquid crystal apparatus includes: a liquid crystal panel (101), an illumination means (109) for illuminating the liquid crystal panel, a supporting means (104,107) for supporting the liquid crystal panel and a housing (108) for housing the above members. The liquid crystal panel and the supporting means are arranged so as to define an almost closed space (124) functioning as an air damper to suppress deformation caused by an externally applied force owing to elasticity of air within the almost closed space. The supporting means includes a unit-supporting portion (107) for supporting the illumination means, the unit-supporting portion being provided with a cutout (122) at a part thereof for promoting discharge of heat evolved from the illumination means, and, the illumination means is supported by the unit-supporting portion so as to stop up the cutout of the unit-supporting portion, thus retaining the almost closed space. The liquid crystal apparatus is further provided with means (125) for enhancing discharge of heat evolved by the illumination means out of the apparatus from a side opposite to the liquid crystal panel of the illumination means.

Abstract: A support structure (3) for supporting a display apparatus (2) which can be tilted vertically upwards or downwards from a predetermined position, is disclosed. This support structure has a tilting mechanism (10) providing a differential torque reaction to an applied tilting force to accommodate a difference in the applied torques required when tilting upwards against the weight of the display apparatus (2) and when tilting downwards assisted by the weight of the display apparatus (2), respectively. In the preferred arrangement, the differential torque reaction is provided by a fixed helical spring (13) and a horizontal axis member (12) at each end (10r,10l) of a support arm (8) provided for supporting the display apparatus (2) on the support structure (3).

Abstract: A liquid crystal display apparatus is constituted by: a housing; a liquid crystal panel comprising a liquid crystal disposed between a pair of substrates each provided with electrodes, the liquid crystal panel being affixed to the housing; and a backlight for illuminating the liquid crystal panel, detachably affixed to the housing. A light-transmissive plate, such as a diffusion plate, allowing transmission of light from the backlight is further disposed between the liquid crystal panel and the backlight so as to define an almost closed first space in cooperation with the liquid crystal panel, whereby the first space retaina its almost closed state even when the backlight is detached from the housing.

Abstract: PROBLEM TO BE SOLVED: To enable each part of a front panel to be operated readily and visibly, regardless of the direction of lengthwise/breadthwise installation in electronic equipment, which can be installed in lengthwise direction where one direction (e.g., longitudinal direction) of a front face of an electronic equipment body is vertical and in a breadthwise direction where it is horizontal, and is provided with a front panel having an operation means, a display means, etc., in the front face. SOLUTION: Units 14, 15, 16 constituting a front panel are fixed detachably to a front face 2d of a body 2 of electronic equipment 1. They can be fixed in a direction parallel to the direction, where a lengthwise direction of each unit is at right angles to the longitudinal direction of a front face 2d by inserting a connector 7b and a boss 12 at the back face of each unit to a connector hole 2e and a boss insertion hole 11 of the front face 2d or inserting them to a connector hole 2e' or a boss insertion hole 11'.
