How to fix the incomplete display on the calculator screen

It may be that the cable connecting the calculator chip and the display (also called the zebra strip) is loose. This fault is very common and difficult to repair; it may also be that the calculator chip is loose. The chip of the device is broken and needs to be replaced.

It is unlikely that the battery is dead, because the symptoms of a dead battery calculator are dim and unclear fonts, errors in the calculator, and data loss. The display is also unlikely to be broken. Special cases cannot be ruled out. The incomplete numbers are just a symptom, there are many real reasons.

I abandoned n calculators because the numbers on the calculator screen were not fully displayed. Try changing the battery. If it doesn't work, change it to a calculator

A calculator is an electronic machine invented by modern people that can perform numerical calculations.

Modern electronic calculator is a handheld electronic machine that can perform mathematical operations. It has an integrated circuit chip, but its structure is much simpler than that of a computer. It can be said to be the first generation of electronic computer (computer), and The function is also weak, but it is more convenient and cheap. It can be widely used in business transactions and is one of the necessary office supplies.

In addition to displaying calculation results, there are often overflow indications, error indications, etc. The calculator uses an AC converter or battery as its power source, and the battery can be recharged with an AC converter or solar converter. In order to save power, calculators use large-scale integrated circuits made with CMOS technology.

Calculator generally consists of arithmetic unit, controller, memory, keyboard, display, power supply and some optional peripherals and electronic accessories, through manual or machine equipment.

The arithmetic unit and controller of the low-end calculator implement simple serial operations by digital logic circuits, and its random access memory has only one or two units for accumulation storage.

High-end calculators use microprocessors and read-only memories to implement various complex calculation programs, and have more random storage units to store input programs and data.

The keyboard is the input component of the calculator, generally using contact type or sensor type.

To reduce the size of the calculator, one button often has multiple functions. The display is the output component of the calculator, including a light-emitting diode display or a liquid crystal display.

In addition to displaying calculation results, there are often overflow indications, error indications, etc. The calculator uses an AC converter or battery as its power source, and the battery can be recharged with an AC converter or solar converter.

In order to save power, calculators use large-scale integrated circuits made by CMOS technology (see complementary metal-oxide-semiconductor integrated circuits), and are equipped with automatic power-off circuits inside when not operating. Optional peripherals for calculators include microprinters, cassette tape drives, and magnetic card machines.
