Abstract

The invention discloses a communication architecture of a display panel. By arranging a time delay circuit, the write-in protection signal can delay the opening of the bus switch after flowing throughthe delay circuit until the process of checking codes in the power supply management integrated circuit is finished, the bus switch cannot be opened when the time sequence controller is checked, andthe checked communication content of the memory is prevented from being rewritten.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a communication framework and a display panel of a display panel. Background technique [0002] After the display panel is powered on, in order to prevent the code in the power management integrated circuit from being rewritten during operation, the timing controller usually checks it at regular intervals. But when described timing controller is carrying out verification, if the communication address of verification just matches with the address of the memory that has stored display information (such as screen type information), the content of described memory will be rewritten (such as screen type information). The information is rewritten), so that, for example, the screen type information cannot be correctly identified, so that the screen of the display panel is abnormal. [0003] Therefore, it is necessary to propose a communication architecture of a display panel a...
