A method for fault detection is adapted for a vehicle display fault detection system. The vehicle display fault detection system includes a vehicle system and a display system. The method for fault detection includes following steps: detecting whether a first state of the display system is abnormal or not; when the first state is abnormal, the display system is configured to generate a fault detection signal; classifying to generate a control signal according to the fault detection signal; and adjusting the first state of the display system to a second state.

Method for fault detection and vehicle display fault detection system

A display apparatus and a driving method of a display panel thereof are disclosed. The display apparatus includes the display panel and a common voltage setting circuit. The display panel has a plurality of pixels and a plurality of common electrode lines and receives a plurality of pixel voltages. Each of the pixels is coupled to the corresponding common electrode line and receives the corresponding pixel voltage. The common voltage setting circuit is coupled to the common electrode lines. A common voltage having a normal voltage level is supplied to the common electrode lines during a first frame period. The common voltage having a complementary high voltage level or a complementary low voltage level is supplied to the common electrode lines during a second frame period. Each of the pixels receives the same pixel voltage during the first frame period and the second frame period.

Display apparatus and driving method of display panel thereof

A method and a detection circuit for selecting a touch detection time are provided. The method for selecting a touch detection time includes the following steps: detecting a noise signal of a touch panel in a first display frame period; determining whether signal strength of the noise signal in a first time segment in the first display frame period is greater than a first noise threshold; and when the signal strength of the noise signal in the first time segment in the first display frame period is less than the first noise threshold, performing touch control in a second time segment in a second display frame period corresponding to the first time segment.

Method and detect circuit for selecting touch detection time

A power management method and a power management device for a display are disclosed, including: comparing contents in an original frame image with contents in a previous image to generate a plurality of successive second periods with first stages and second stages, shortening a plurality of time intervals in the first pulse timing distribution and outputting the first pulse timing distribution for displaying a first sub-frame image on the display during the first stage of one of the plurality of successive second periods, and shortening a plurality of time intervals in the second pulse timing distribution and outputting the second pulse timing distribution for displaying a second sub-frame image on the display during the first stage of the other one of the plurality of successive second periods; and turning off the driving circuit of the display in the second stages.

Power management method and power management device

A scaling-up control method and a scaling-up control apparatus are used in a display device. The display device includes a scaler for converting an original image signal into an output image signal by performing a linear interpolation. Moreover, by utilizing a global locking mechanism and a local locking mechanism to perform the linear interpolation to determine the actual position of the interpolated pixel, the position error of the pixel position is largely reduced. Since the difference between the calculated pixel value and the ideal pixel value is reduced, the imaging quality of the output image signal is enhanced.
