Description
Technical field
The present invention relates to the communications fields, are situated between in particular to the determination method, apparatus of angle, storage between a kind of screen
Matter and electronic device.
Background technique
Multi-screen terminal (for example, Dual-band Handy Phone, as depicted in figs. 1 and 2) is carrying out single screen to when multi-screen switching, and being need to
Carry out pattern switching, be illustrated by taking double screen terminal as an example below: double screen terminal can there are three types of mode, specific moulds at present
Formula schematic diagram can be found in Fig. 3, in which:
When the Hall sensor in terminal detects that the folding angles between double screen are 0 °, determine that present terminal is in folding
Folded single screen state；
When the Hall sensor in terminal detects that the folding angles between double screen are greater than 0 ° less than 180 °, determine current
Terminal, which is in, is non-fully unfolded double screen state；
When the folding angles between the Hall sensor detection double screen in terminal are 180 °, determine that present terminal has been in
Full expansion double screen state；
Wherein, the mode that terminal is presently in can pass through the hall sensing in the shaft that is mounted between the double screen of terminal
Device (for example, digital hall sensor) is judged；When terminal factory, producer can be to the folding angles between double screen
It is calibrated for 30 ° and 150 ° of two angles, and using the two angles as 0 ° and 180 ° of activation threshold value.Correspond to
The mode (that is, mode corresponding to the angle detected) of three kinds of number hall (Hall sensor) angles, double screen project has four
Kind display pattern: single A, big A, A | B, A | A；After the angle mode for detecting digital hall, terminal is just allowed to be switched to corresponding
Display pattern.
As shown in Figure 1, only allowing terminal works in single A display pattern when the folding angles between double screen are 0 °；For
(30 °, 150 °] when, allow terminal works in A | A display pattern；For (150 °, 180 °] when, allow terminal works in A | B and big A
Two kinds of display patterns.
It should be noted that digital hall sensor is in use, it is possible that the case where high temperature demagnetization, or
Person, the variation of magnet and digital hall sensor distance caused by being loosened, gently fallen due to shaft, also results in magnetic flux and becomes
Change.
If once 0 ° of magnetic flux is less than the threshold value of 30 ° of producing line calibrations, digital hall sensor " CLOSE=will lead to
0 ° " state can not again trigger, Dual-band Handy Phone can not automatically switch display under single mode A after folding, lead to disabler.
Equally, if once 180 ° of magnetic flux is greater than the threshold value of 150 ° of producing line calibrations, it will lead to digital hall sensor
The state of " OPEN=180 ° " can not again trigger, and Dual-band Handy Phone can not automatically switch big A and A after folding | it is shown under B-mode,
Lead to disabler.
Wherein normal magnetic flux schematic diagram is as shown in figure 4, the magnetic flux data after high temperature demagnetization are as shown in Figure 5.
After digital hall sensor failure, display function is abnormal, and mobile phone must be taken after sale, be passed through after sale by user
Angle with calibration angle (30 ° -150 °) is recalibrated, and calibrating mode can refer to Fig. 6.But by being calibrated after sale
Mode to will lead to user experience low, and maintenance cost is higher.
