Embodiment Construction

[0036] The front panel of the housing of the calculator is a liquid crystal touch display screen as a whole, which is composed of a liquid crystal screen and a touch screen superimposed together. When the calculator is working normally, the display area of ​​the LCD touch screen is as follows: figure 1 As shown in the display, it includes two areas: digital input result display area, operation and mode setting command area.

[0037] In the number input result display area: the upper right corner is the mode prompt area, which is used to prompt the current mode of the calculator: calculator mode or abacus mode; for example figure 1The mode it is in is the abacus mode; the middle and lower part is the number input display area corresponding to the maximum number of digits of the calculator. The outside of the above digital input display area is as follows: figure 1 The circular digital prompt area that evenly displays 0-9 ten-digit numbers is shown, and the interior is a digit...

Abstract

The invention provides a touch screen calculator and a bit-based input and calculation method thereof. The touch screen calculator comprises a calculator main body with a touch screen; the calculator main body is provided with a calibration button; a calculation and mode command setting region and a digital input result display region are arranged on the touch screen of the calculator main body; a calculation command button and a calculator / counting frame mode switching button are arranged in the calculation and mode command setting region; digital input display regions of which the number corresponds to the maximum digit of the calculator, and a mode indication region are arranged in the digital input result display region; and the calculator main body further comprises a detection module, a judgment module and an execution module. By using a touch screen technology, the problems that digital keys and digital display of the calculator are not in the same visual range, and bit-by-bit input of the calculator are solved according to program control; furthermore, intuitive effects of instant dialing, instant calculating and instant obtaining of addition and subtraction of the counting frame are simulated according to inner program control.

Description

technical field [0001] The invention relates to a novel calculator and a realization method, belonging to the application field of electronic technology. The utility model aims at overcoming the disadvantages of the existing abacus and the calculator, exerting the advantages of the abacus and the calculator, and realizing a new calculation tool. Background technique [0002] For many years, the "popular and convenient" computing tools are calculators and abacus. Different types of users have different evaluations and preferences for these two computing tools. This leads to an undeniable fact: calculators and abacus have their own advantages and disadvantages. In the face of this fact, if objectively there is a calculation tool that can fully inherit the advantages of calculators and abacus and eliminate their shortcomings, then this calculation tool will definitely be able to replace calculators and abacus. In this context, many scientific and technical personnel have anal...
