近几年来,由于集成电路的大量生产,数字仪表的发展,也随着进入了一个崭新阶段,简化了仪表的内部结构和连接线路;提高了精度等级和其他的使用性能;大大缩小了体积和重量。但是,要达到所有这些发展中的技术要求,对于数字仪表的读数显示方式及其器件,必然也相应地提出新的技术指标,如显示器件的驱动,要求直接使用集成电路,而功率消耗要低,动作要可靠,使用寿命要长,以及体积和重量等都要小。最近发展的荧光数码管、磷光体数码管以及液晶等显示器件,基本上体现了上述的技术要求,因此,可以说这些新型显示器件的出现,对数字仪表的发展,提供了必要的保证。
In recent years, due to the mass production of integrated circuits, the development of digital instruments has also entered a new phase with the simplification of the internal structure and connection lines of the instruments, the improvement of the accuracy class and other operational performances, the significant reduction in volume and weight. However, in order to meet all of these developing technical requirements, digital display readings and their devices inevitably also come up with new technical indicators, such as the display driver, which requires the direct use of integrated circuits and low power consumption , Action should be reliable, longer life, as well as smaller size and weight. The recent development of fluorescent digital tube, phosphor digital tube and LCD and other display devices, basically reflects the above technical requirements, it can be said that the emergence of these new display devices, the development of digital instrumentation to provide the necessary guarantees.
