摘要： Disclosed herein are an apparatus and a method for driving an e-paper panel. The e-paper panel driving apparatus includes a DC/DC converter that converts and outputs DC voltage to be input into a preset voltage and supplies the output voltage as a driving voltage of an e-paper panel; a sensing module that senses load conditions of the e-paper panel; and a control module that varies the driving frequency of the DC/DC converter according to the load conditions of the e-paper panel sensed by the sensing module. According to the present invention, the driving clock of the DC/DC converter that supplies the driving voltage to the e-paper panel is varied in consideration of the load conditions of the e-paper panel, thereby making it possible to prevent an image quality of the e-paper panel from being degraded due to unstable power supply, while simultaneously minimizing unnecessary power consumption of the e-paper panel driving apparatus.

摘要： The present general inventive concept relates to a method of compensating tilt using a two-axis geomagnetic sensor and an acceleration sensor and an apparatus. Using the principle where a geomagnetic field value measured in a state where one axis of the two-axis geomagnetic sensor is set up vertically is identical to a Z-axis geomagnetic field value, the Z-axis geomagnetic field value can be evaluated by using two axes of the two-axis geomagnetic sensor. Accordingly, an azimuth angle can be easily calculated, so that the azimuth angle changed by tilt can be compensated. Therefore, there is an effect that a constant azimuth can be always output even though tilt occurs. In addition, when a module of the two-axis geomagnetic sensor and the acceleration sensor is used in a mobile equipment, the two-axis geomagnetic sensor can automatically measure geomagnetic field values of three axes by a simple motion where a user vertically sets up or rotates up and down the mobile equipment. Therefore, there is an effect that a constant azimuth angle can be always output by compensating the azimuth angle changed by tilt.
摘要翻译：本发明总体构思涉及使用两轴地磁传感器和加速度传感器以及装置来补偿倾斜的方法。使用在两轴地磁传感器的一个轴垂直设置的状态下测量的地磁场值与Z轴地磁场值相同的原理，Z轴地磁场值可以通过使用两个双轴地磁传感器的轴。因此，可以容易地计算方位角，从而可以补偿由倾斜变化的方位角。因此，存在即使发生倾斜也能够始终输出恒定方位角的效果。另外，当在移动设备中使用双轴地磁传感器和加速度传感器的模块时，双轴地磁传感器可以通过简单的运动自动测量三轴的地磁场值，用户垂直设置或在移动设备上上下旋转。因此，通过补偿由倾斜变化的方位角，可以总是输出恒定方位角的效果。

摘要： An automatic calibration method for use in an electronic compass. Using the automatic calibration method, the electronic compass automatically calculates and corrects offset and scale values of a geomagnetic signal by detecting one rotation of a geomagnetic axis during a predetermined period of time. The electronic compass calculates an azimuth angle upon receiving geomagnetic data from the geomagnetic sensor, and finds maximum and minimum values of sensor signals of individual axes of the geomagnetic sensor using the received geomagnetic data such that it can correct or calibrate deviation of the azimuth angle. When a time consumed for calibration is the same or shorter than a maximum calibration effective time, the electronic compass determines whether a current state of the detected entry signal indicates a predetermined steady-state flow. If the current state indicates the steady-state flow, at the same time a signal indicative of one rotation of the geomagnetic sensor is received, and the time consumed for calibration is longer than a predetermined minimum calibration effective time, the electronic compass calculates offset and scale values using the maximum and minimum values and stores the calculated offset and scale values.
