Abstract

An apparatus and method for sensing a rotary switch handling direction of a monitor is disclosed, in which a simple configuration can be obtained and accuracy in sensing a handling direction can be enhanced. The apparatus for sensing a rotary switch handling direction of a monitor includes a rotary switch for outputting voltage levels varied correspondingly depending on a user's handling direction, and a microcomputer for storing the voltage levels output from the rotary switch and comparing the voltage levels with a previously stored voltage change/handling direction table to determine a handling direction of the rotary switch. Since the handling direction is sensed by the voltage level difference for respective contacts, it is possible to exactly sense the handling direction and to relatively obtain a simple configuration.

5293〇 V. Description of the invention G) Description of the invention Field of the invention The present invention relates to a method and a device for controlling the direction of a monitor and a special knob.一种 In a type of surveillance Background of the Invention Natural questions, such as: The screen is larger, so the monitor monitor adjustment device cannot adjust the screen display normally. To solve the problem, the user can show the current market, as shown in Figure 1. Rotary turntable 24 heart 2 6 Development, and nowadays, it is more and more common to display a balance monitor and focus on the above problems. When we show different errors, adjust the screen display. For such problems, the knob on the market can be selected by turning the knob, as shown in the conventional knob. Rotating the turntable 24 and the central axis, the fixed turntable 2 2 includes a plurality of = the requirements for the quality of the monitor's daytime surface also have many problems in adjustment and calibration, such as poor and chromaticity errors, and the monitor is serious. ° Zhou Bu Changzhi to overcome the above problems. A switch for dimming the screen belongs to this calibration mode. Using this type of switch makes it difficult for the user to accurately control the switch. A rotary switch appears on the screen to select the screen adjustment mode. Figure off.

V. Description of the invention (2) Separate distribution On the circumference centered on the common axis 26. The rotary dial 24 includes two switches SWA and SWB. SWA and SWB are fixed on the rotary dial 24 and are located on the same circumference at a specific angular interval. Figure 2 shows the circuit configuration of the conventional rotary switch. As shown in FIG. 2, the circuit of the conventional rotary switch includes two switches swA and SWB, a resistor R1, a capacitor C, and a switch SWU. Among them, the switches SWA and SWB both have one end connected to the resistor R2, and connected to a 5 volt power supply terminal through the resistor R2, and the other ends of the two switches are grounded.

The following describes a conventional method for sensing a steering direction of a rotary switch. Assuming that a user rotates the rotary dial 24 in a preset direction, the switches SWA and SWB will contact the conductive sheet on the fixed dial 22. As shown in Figure 3, at this time, the pulse generator will generate output pulses PA and ", and are output by SWA and SWB respectively. At this time, because the relative positions of SWA and SWB are fixed (see Figure 2), when rotating When the turntable 24 rotates, the output pulse pA is generated first, and then the output pulse PB QPA and the time difference between PB are expressed as 12. The actual time difference varies depending on the speed at which the user rotates the turntable 24. Suppose there is a use today The direction in which the user rotates the rotary dial 24 as described above

529301 V. Description of the invention (3) In the opposite direction, the output pulse pB is generated and the time difference between the output pulse PB and PA will precede the output pulse PA. 24 speeds vary. Therefore, by ^ rotating the turntable with the user ": sensing the phase difference of the user turning the rotary ::: = ㈣, there are many problems with Baizhifang's button. One is the connection of the knob switch operator.
