HDLS-1414中文资料Four Character Smart Alphanumeric Displays数据手册Broadcom规格书

描述 Description

These are 3.7 mm (0.145 inch) four character 5 x 7 dot matrix displays driven by an on-board CMOS IC. These displays are pin for pin compatible with the HPDL-1414. The IC stores and decodes 7-bit ASCII data and displays it in an easy to read 5 x 7 font. Multiplexing and LED drive circuitry is also included in the display, and fast setup and hold times allow it to interface easily with common microprocessors. The address and data inputs can be directly connected to microprocessor address and data buses. The HDLS-1414 offers a larger character set than the HPDL-1414. Lower case letters and special symbols are now offered, made possible by the 5 x 7 dot matrix character layout. The difference between the sunlight viewable HDLS-1414 and the low power HDLU-1414 lies in the brightness level. The sunlight viewable version is internally set to provide high intensity characters. The low power version uses the same bright LED technology, but reduces the current through each LED to a much lower level, and maintains an intensity comparable to the HDLO-1414.

简介

HDLS-1414属于光电器件的显示器模块-LED点阵群集。由制造生产的HDLS-1414显示器模块 - LED 点阵和群集显示器模块 - LED 点阵和群集装置是使用布局成矩阵形式的发光二极管来提供可视图形的器件。它们通常以网格状排列，发光二极管的正或负端子连接在一起作为公共电路节点。这些装置具有各种尺寸和颜色，并且可以接受各种接口，包括 I2C、8 位并行、串行和 ASCII 输入。
