  • Publication number: 20210295764
    Abstract: A display device and a driving protection method thereof are provided. The display device includes a timing controller and a source driver. The timing controller encrypts a verification data to generate a first encryption signal. The source driver coupled to the timing controller receives the first encryption signal. The source driver decrypts the first encryption signal to obtain a first decryption data. The source driver encrypts the first decryption data to generate a second encryption signal. The source driver outputs the second encryption signal to the timing controller. The timing controller decrypts the second encryption signal to obtain a second decryption data. When the timing controller determines that the second decryption data matches the verification data, the timing controller enables the source driver to perform display driving.

  • Patent number: 8884605
    Abstract: A detecting circuit for detecting a feedback voltage of a pixel circuit includes a converting unit, a control chip and a display unit. The converting unit electrically connected to the pixel circuit performs an analog-to-digital operation to convert the feedback voltage into a digital signal. The control chip electrically connected to the converting unit controls the converting unit to perform the analog-to-digital operation and processes the digital signal to generate a display information. The display unit electrically connected to the control chip displays a voltage value of the feedback voltage according to the display information.
