Digital tube has: low energy consumption, low loss, low pressure, long life, aging resistance, sunscreen, moisture-proof, fireproof, high (low) temperature, low requirements for the external environment, easy maintenance, high precision, fast weighing, accurate and reliable, simple operation. Digital display is adopted
Digital tube has the following features: low energy consumption, low loss, low voltage, long service life, aging resistance, sunscreen, moisture-proof, fireproof, high (low) temperature resistance, low requirements for the external environment, easy maintenance, high precision, fast weighing, accurate and reliable, simple operation.
Digital display uses BCD code to display numbers and codes.
it is easy to program, Less resources are used.

.
LED display is also a kind of liquid crystal display.
LED replaces the traditional liquid crystal backlight module.
high brightness.
and can achieve stable brightness and color performance within the life span.
wider color gamut.
achieve more brilliant colors.
it is easy to control.
because of the use of solid-state light-emitting devices.
it has strong adaptability to the environment, Therefore, LED has the advantages of wide temperature range, low voltage and impact resistance.
moreover, LED light source does not produce any radiation.
low electromagnetic radiation and mercury free are green light sources.
.
to sum up, LED LCD TV has the advantages of power saving, environmental protection, low cost and low cost The advantages of color are more realistic.
.
.
the important aspects of type comparison are: structure and product volume.
radiation and electromagnetic interference, screen flatness and resolution, and display effect (the brightness of traditional CRT display is better than that of liquid crystal display, the visual angle is also much better, and the display speed is almost the same) {LCD overcomes the shortcomings of CRT, such as huge volume, power consumption and flicker, But at the same time, it also brings some problems, such as high cost, not wide viewing angle and color display is not ideal.
CRT display can choose a series of resolutions.
and can be adjusted according to the requirements of the screen, but the LCD screen only contains a fixed number of liquid crystal units, and can only use one resolution display (each unit is a pixel) in the full screen
12864.
dot matrix liquid crystal display module (LCD) is widely used in single-chip microcomputer control system.
it can display more and more intuitive information than digital tube and Segment LCD.
12864 LCD belongs to dot matrix graphics LCD module.
it can not only display characters, but also display Chinese characters and graphics. The display area is large, the display of numbers and Chinese characters is easy to realize, and the program requirements are not very high, It is easy to operate.
lattice LCD module is highly integrated.
generally, it has built-in control chip, row driver chip and column driver chip.
