Digital display LED nixie tube

Abstract

The invention aims to solve the problem of how to reduce misreading caused by connection when an LED nixie tube shaped like a Chinese character 'ri' displays a figure 1, and meanwhile, the displayed figure 1 is attractive. A digital display LED nixie tube is an LED nixie tube shaped like a Chinese character 'ri' and is characterized in that the upper edge of the Chinese character 'ri' is transversely divided into a left segment and a right segment which are respectively called as an upper left segment and an upper right segment for short, and only the upper right segment and the right side ofthe Chinese character 'ri' are vertically lightened when the digital display LED nixie tube displays the figure 1. The beneficial effects are that the upper right segment enables the distinction degree of the figure 1 and other figures to be higher, and misreading caused by connection of the figure 1 and the right figure is avoided; besides, the upper right segment enables the figure 1 to visuallyshift leftwards integrally, so that the left space is effectively utilized, and the unattractive appearance of the figure 1 which is too close to the side is relieved to a certain extent; meanwhile,' / ' enables the displayed figure 1 to be similar to a common thick figure, a small hook is arranged on the figure 1, the figure 1 is thickened when the LED nixie tube is used for displaying, and the thickened figure1 is very attractive.

Description

technical field [0001] The invention relates to the technical field of information display, in particular to a digital display LED digital tube. Background technique [0002] LED digital tube is composed of multiple light-emitting diodes packaged together to form a fixed-shaped device. The lead wires have been connected internally. It only needs to lead out their pen segments and common electrodes, and control the brightness of each segment on the digital tube through single-chip microcomputer programming. Show different numbers. Nixie tubes are a carrier for displaying digital information. Compared with dot matrix screens, nixie tubes are more cost-effective and reliable. LED digital tubes are widely used in LCD screens for displays such as electronic watches, calculators, and digital multimeters. At present, the "day"-shaped LED digital tube usually composed of seven segments is used the most (that is, the seven-segment "8"-shaped LED digital tube is usually called, and ...

Problems solved by technology

[0003] However, there are two important problems. First, when the number 1 is displayed, usually the right side of the word "日" is lit vertically, and sometimes it is closely connected with the number on the right side to cause misreading, for example figure 2 As shown, the number 13 is close together, and it is easy to read as 8 in the case of a long distance or poor eyesight; secondly, when the number 1 is displayed, it is relatively close to the side, and at the same time, there is a large area on the left of 1, which is not beautiful and generous.
