- SSL LED Prices back than where between $4 and $32 apiece. General Electric was one of the first companies to offer a visible light emitting diode in 1967. The earliest LED’s, light emitting diodes, were produced in the early 1960’s. Long leads also serve as a heat sink to prevent damage to the plastic enclosure. One of the Very First LED displays - built in Cleveland by General Electric at the original Nela Lamp Plant. Nela Park was the first industrial park in the world being home to most of the lighting breakthroughs of the last century. The SSL-140's dies are bonded to a ceramic wafer with gold leads, with an enclosing plastic cover to protect the fragile dies and bond wires. The display's decimal point is a separate small cubical die located in the right side of the display area.
The SSL-140 is a single die device, in that all of the segments are constructed on the same lump of silicon. One of General Electric's most well-known displays, the SSL-140 is an early seven-segment LED in a tiny surface mount package. General Electric - SSL-140 - LED Displays, Solid State Lamp (SSL) 0.175" character spacing allowing as much as 32 characters in 5.6" linear panel space.Įight (8) Characters, 14 segment, Common Cathode, Red.Voltage and current compatibility for interfacing ease with microprocessors and related circuitry.Complete Alpha-numerics plus special characters.Low Power Consumption (As low as 0.5 mA average current or 1.0 mw per segment.) Each character is constructed from a monol ith ie, red GaAsP chip formated into a 14-segment font with a decimal point. The MAN2815 is an eight-character alpha-numeric display which is end-stackable and capable of displaying all alpha and numeric characters plus symbols. General Instruments - MAN2815 - Opto Display. Vintage New Old Stock - 1970s Vintage - Rare Super Cute 7.62mm (0.300 in) High Characters. Same display units as used in the classic SR-60 Programmable Calculator.Īlphanumeric Alpha-Numeric Dot Matrix Display. Uses a standard HUB08 connection, so you can use the PLT-1001 driver boards to control it. Pixels can show as black (that is, completely unlit), or red. The module is based on eight LRT1704R display modules (equivalent the TI元07 display) and two TLC5920 from TI which allows all those LEDs to be controlled with only 7 microcontroller I/O lines. The LDP-080705R is a retro red color 8 digit 5x7 (+ decimal) pixel LED matrix display. IEE has over 70 years of experience building custom military and industrial displays.
