The PD4436 is a display module with a bright LED dot matrix and cluster from EVERLIGHT ELECTRONICS Co., Ltd. It is an ideal solution for LED display applications needing an easy to interface dot matrix display, especially suited for embedded control applications. It features a wide viewing angle and low power consumption, as well as low cost. The PD4436 is capable of displaying alphanumeric and other symbols in a range of formats.In terms of physical size and shape, the PD4436 has a single piece construction making it easy to assemble onto a PCB. It is available in two variants, one 7.2 wide and 5.6 deep, and the other 5.6 wide and 4.8 deep. The latter is the more compact version, while the former is more visible in bright environments.In terms of technical specifications, the PD4436 consists of 36 clusters of red LEDs arranged in a 7x5 matrix. Each cluster is a single-level (SL) or double-level (DL) display depending on the application. The peak brightness of each cluster is up to 20 mcd/sq. cm and the operating temperature ranges from -20° to +50°C.In terms of interfacing, the PD4436 uses an 8-bit shift register IC to provide a low-level active-level interface for data transfer. The functions of the IC include loading data into the shift register and shifting the data one byte at a time until the desired symbol has been achieved. Data is clocked in at a frequency of 500kHz.Apart from the 8-bit shift register interface, the PD4436 also features a data input with an 8-bit latch IC, enabling users to send binary data directly to the display. This can be used in various applications such as controlling multiple symbols, scrolling, and displaying text and symbols.In terms of applications, the PD4436 can be used in a range of embedded control applications such as instrumentation, medical devices, toy and gaming devices, LED signs, and LCD backlighting. It is also suitable for digital clock displays and decorative applications. The PD4436 is compatible with all types of microcontrollers and digital signal processors (DSPs) including MCU, PLC, Raspberry Pi, Freescale, and STM.To summarize, the PD4436 is an LED dot matrix and cluster from EVERLIGHT ELECTRONICS Co., Ltd., designed for applications involving embedded control and LED display applications that require ease of interface. It features a single-piece construction, a wide viewing angle, low power consumption, low-level active-level interface, and data input with an 8-bit latch IC. It can be used in a range of embedded control applications and is compatible with all types of microcontrollers and digital signal processors.
