摘要： An electrically operated, signal magnitude display device of a non-mechanical, compact type suitable to substitute for a panel meter, with the capability of converting an input digital electrical signal into a visual analog display wherein the magnitude of the input signal is to be represented by an appropriate indication of position within the field of the display. The device comprises a display section having a plurality of electrically activatable luminous elements, such as luminous diodes, arranged in a one-dimensional array so that the elements may be independently activated to luminesce and thereby serve to visually define an incrementally variable position within the array. An electrical circuit, interconnecting with the luminescent element terminals through respective intersecting common groups of terminals in a matrix circuit, responds to the input signal and selects the specific luminous element positioned in the array to correspond to the magnitude of the input signal. In a practical example, the electrical circuit receives, e.g., two digits of a binary coded decimal input signal and converts them to two decimal signals gating two intersecting groups of ten terminals in the matrix circuit to form an activation circuit through the one luminescent element whose terminals appear in the two groups.
