Abstract
Abstract An information board apparatus has a display mechanism unit formed by arranging multiplicity of multicolor light-emitting members in a grid pattern, each of the members being constituted by a plurality of light-emitting diodes housed in a lamp case which has a heat-dissipating bore formed in its side plate portion at which the respective lead portions of the diodes are located.The display mechanism unit is attached to the front frame of the body of the apparatus. When this apparatus is employed for displaying for example, road traffic information, the apparatus strongly attracts attention and permits the displayed information to be clearly seen.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
An information display apparatus which comprises a display unit which is made of a number of multicolored light emitting devices arrayed in the checkerboard pattern, a control unit which selects one or more display patterns from different display patterns stored in semiconductor storage devices and sends out the control signal concerning unit which lights the multicolored light emitting groups in response to the selected display pattern or patterns, adjust their brightness, and flicker them unit which lights the multicolored light emitting device groups in response to the selected display pattern or patterns, adjusts its or their brightness, flickers the light of the light emitting devices, and changes the lighting color of the light emitting device groups as required.
Claim 2
Dependent Claim
