  • FIG. 2A shows an [0028] LC screen 1 or panel or cell in the form of a substantially rectangular plate with a thickness and a back light unit 2 in the form of a substantially rectangular plate with accessories at both sides, as they are left flat and extend straight, as principal components of an LCD according to an embodiment of the invention. The back light unit 2 is composed of a single sheet 3 of a flexible resin assisted for light emission with a pair of light sources 5 extending along both sides thereof and protected with a pair of reflection covers 6. Rays of light transmitted from the light sources 5 are emitted from the sheet 3. A light emitting side of the resin sheet 3 faces a light receiving back side 1 a of the LC screen 1.
  • FIG. 2B shows the [0029] LC screen 1, as it is curved to provide a rearwardly arcuate display surface, and the back light unit 2, as it is curved along the back side 1 a of the LC screen 1 substantially parallel to the arcuate display surface. The display surface of the LC screen 1 may be curved forwards, as well as rearwards, to be a wholly or partially quadratic or higher-degree surface, such as a cylindrical surface about a vertical, oblique or horizontal axis, a parabolic or highperbolic surface, or a spherical or spheroidal surface, alone or in combination, as well as in other embodiments of the invention.
  • FIG. 3 is an exploded view of a meter apparatus M for vehicles including an LCD according to an embodiment of the invention. The meter apparatus M comprises a rearwardly curved front or [0030] observation glass assembly 14, a rearwardly curved reverse assembly 13 as a supporting distance frame disposed behind the observation glass assembly 14, the LCD including a rearwardly curved LC screen 1 as a meter board disposed behind the reverse assembly 13 and a rearwardly curved back light unit 2 with a pair of rubber shielded flexible conductor combination members 18 at both sides, an LCD holder 16 as a straight support frame disposed behind the back light unit 12, a flat printed circuit board 19 disposed behind the LCD holder 16, and a shaped meter casing member 12 substantially horizontally extending behind the circuit board 19.
  • The [0031] LC screen 1 displays, on its front face, at a left side thereof e.g. a signal indicator 1 b, an alarm indicator 1 c and a speedometer 14 a, and at a right side thereof e.g. a temperature gauge 1 d, a fuel gauge 1 e and a tachometer 14 b. A driver naturally looks the left side, and a navigator naturally looks the right side, as the LC screen 1 is symmetrically curved with respect to an imaginary central vertical plane.
  • The [0032] back light unit 2 comprises a rearwardly curved sheet 3 of a flexible transmitted-light emitting resin, and a pair of left and right lighting devices each including a sheet-edge illuminating light source 5 connected via a cord to a power supply (not shown).
  • The [0033] LCD holder 16 is constituted as an LCD supporting connector assembly including an insulating rigid connector housing member formed with: a rearwardly curved central front face 16 a for a back side of the curved light emitting sheet 3 to rest thereon; a pair of upper and lower straight side portions 16 b for holding and supporting upper and lower edges of the curved light emitting sheet 3; and a pair of left and right connector housing portions 16 c cooperating at their inner sides with the front face 16 a and respective inner sides of the upper and lower side portions 16 b to define an arcuate accommodation space for accommodating therein the curved light emitting sheet 3. The accommodation space may accommodate therein the LC screen 1, as well. Each connector housing portion 16 c is formed with a vertically extending front slot 17 to fit on a rear connector portion 18 a of the conductor combination member 18. Pin connectors (not shown) are provided through the connector housing 16 c for electrical connection between control circuits on the printed circuit board 19 and the rear connector portion 18 a of the conductor combination member 18, which member 18 has a front connector portion 18 b adapted for electrical connection to signal lines in the LC screen 1, and LC control signals are conducted from the printed circuit board 19 via the pin connectors and the conductor combination member 18 to the signal lines in the LC screen 1.
  • The [0034] back light unit 2 may comprise a rearwardly curved rectangular sheet of a flexible body of an electroluminescent substance, such as a curved electroluminecent panel or cell, and a drive circuit for application of a sufficient voltage for excitation of the substance to produce and emit a necessary density of light flux.
  • It will be seen that an LCD according to another embodiment of the invention may comprise an entirety of the meter apparatus M. [0035]
  • FIG. 4 shows a flexible [0036] back light unit 2 according to an embodiment of the invention, as it is left flat for comprehension. This back light unit is identical to or may substitute for a respective back light unit in the embodiments described. The back light unit 2 comprises a rectangular single sheet 3 of a flexible transmitted-light emitting resin body, and a pair of left and right lighting devices each composed of a sheet-edge illuminating straight light source 5 and a back reflector 6 semi-circular or parabolic in section about the straight light source.

The particles 4 have a refractive index different from that of the synthetic resin. The single sheet 3 is adapted for a brightness control or light density smoothing, a light scattering distribution, and a light transmission for emission, as illustrated by arrows.
  • As illustrated by two-dot chain lines in FIG. 4, the lighting devices may be replaced by a matrix of LED's applied over a back side of the flexible [0037] light emitting sheet 3 in a plane conforming manner.
  • While preferred embodiments of the present invention have been described using specific terms, such description is for illustrative purposes, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims. [0038]
