The content of the user behavior table includes: the user name and the contrast of the intelligent tablet display screen and the brightness of the intelligent tablet display screen each time the user uses the intelligent tablet display screen; Preprocess the data corresponding to the user behavior table, extract the display preference features of each user, and at the same time, construct a display preference feature dictionary and store the display preference features of each user in the display preference feature dictionary; At the same time, create a user identification field according to the user name; construct a hyperlink between the user identification field and the corresponding display preference feature in the display preference feature dictionary; When performing display control on the intelligent tablet display screen, obtain the target user information of the currently used intelligent tablet, and determine the target user identification field according to the target user information; Input the target user identification field into the display preference feature dictionary, and locate the target display preference feature of the target user according to the hyperlink; Determine the preferred contrast and preferred brightness of the intelligent tablet display screen for the current target user according to the target display preference feature; Correct the contrast and brightness of the intelligent tablet display screen according to the preferred contrast and preferred brightness.

9. The display control method for a smart tablet according to claim 8, characterized in that, Correct the contrast and brightness of the intelligent tablet display screen according to the preferred contrast and preferred brightness, including: Read the target contrast and target brightness output based on the intelligent tablet display control model; Calculate the contrast mean of the preferred contrast and the target contrast. At the same time, calculate the brightness mean of the preferred brightness and the target brightness; Perform a first correction on the target contrast according to the contrast mean. At the same time, perform a second correction on the target brightness based on the brightness mean; Control and adjust the contrast and brightness of the intelligent tablet display screen according to the first correction result and the second correction result.

10. A display control system for a smart tablet, which is used to implement the display control method for a smart tablet according to any one of claims 1-9, characterized in that, Including: An intelligent tablet usage judgment module configured to judge whether the intelligent tablet is in use; An intelligent tablet state switching module configured to switch different display states of the intelligent tablet according to the intelligent tablet usage judgment result; A tablet display data acquisition module configured to acquire real-time data of the intelligent tablet display; A tablet display data processing module configured to process the acquired real-time data of the intelligent tablet display to determine the intelligent tablet display characteristic data; An intelligent tablet display control module configured to perform display control on the intelligent tablet and intelligently adjust the contrast and brightness of the intelligent tablet display screen.
