1. An operating method for adjusting a brightness level of a touch display device with a touch display panel, comprising:
- detecting a touch motion performed on the touch display panel;
thenadjusting the touch display panel to display images with a reduced first brightness level from a higher previous brightness level based on the touch motion detected;
thendetecting a distance between a user and the touch display panel to evaluate if the distance is greater than or equal to a preset distance; and
thenif the distance is evaluated to be greater than or equal to the preset distance, adjusting a brightness level of the touch display panel to display images with an increased second brightness level from the reduced first brightness level, wherein said increased second brightness level is the same as the higher previous brightness level, andif the distance is evaluated to be less than the preset distance, maintaining the brightness level at the reduced first brightness level and again detecting the distance between the user and the touch display to again evaluate if the distance is greater than or equal to the preset distance.

10. A touch display device with a touch display panel, comprising:
-
a touch motion detector for detecting a touch motion performed on the touch display panel; a distance detector for detecting a distance between a user and the touch display panel; and a processing module, coupled to the touch motion detector and the distance detector, wherein the processing module includes a processor configured to adjust the touch display panel to display images with a reduced first brightness level from a higher previous brightness level based on signals from the touch motion detector, and then determine if the distance is greater than or equal to a preset distance based on distance detected by the distance detector, and if the distance is greater than or equal to the preset distance, adjust a brightness level of the touch display panel to display images with a higher second brightness level from the reduced first brightness level, and if the distance is less than the preset distance, maintain the brightness level of the touch display panel at the reduced first brightness and then again determine if the distance is greater than or equal to the preset distance based on another distance detected by the distance detector; wherein the touch motion detector comprises a pressure sensor or a touch sensor and the distance detecting module comprises a camera, an infrared sensor or an acoustic sensor; and
further comprisinga storage module coupled to the processing module, wherein the storage module is configured to store the reduced first brightness level and the higher second brightness level of the touch display panel before the touch motion. - View Dependent Claims (11, 12, 13, 14, 15, 16)
