Embodiment Construction

[0036] Please refer to Figure 2A , Figure 2A A schematic diagram of an electronic device 200 according to an embodiment of the present invention is shown. The electronic device 200 includes a processing unit 210 , a touch controller 220 , a memory 250 , a display driver 231 and a panel 232 configured in the display module 230 . Wherein, the panel 232 integrates a plurality of touch detection units for detecting touch actions and a display panel for displaying images. In order not to interfere with the displayed image, the touch detection unit can be formed by using a transparent conductive film made of light-transmittable Indium Tin Oxide (ITO). Wherein, the panel 232 includes a plurality of touch units and a plurality of display units.

[0037] The processing unit 210 is coupled to the touch controller 220 and the display driver 232 . The processing unit 210 sets the scan frequency TCF and the display frequency DSF respectively, and transmits the set scan frequency TCF ...

Abstract

An electrical apparatus having a panel is disclosed. The electrical apparatus includes a processor, a touch controller and a display driver. The processor unit sets one of a scan frequency and a display frequency to be a setting frequency, and generates the other of the scan frequency and the display frequency based on the setting frequency. The touch controller makes the panel detects a touch based on the scan frequency, and the display driver makes the panel display images based on the display frequency. The touch controller detects a noise detected value from the electrical apparatus. The touch controller or the processor unit adjusts the setting frequency based on the noise detected value, and adjusts the touch scan frequency or the display frequency which is not the setting frequency based on the setting frequency.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a method for setting and dynamically switching the working frequency of the electronic device. Background technique [0002] With the development of electronic technology, it is the main trend of modern consumer information products to provide touch function on the display panel so that users can directly control graphics and / or text by touch. In order to reduce the space occupied by electronic products, designers propose a panel that integrates a display panel and a touch panel into a panel that also has a touch display function. [0003] This known integrated electronic device will change the frequency used for touch detection when the noise generated by it is too large, so as to reduce the original operating frequency used for touch detection On the noise that electronic devices may generate. However, due to such an integrated electronic device, the available frequency for...
