Problems solved by technology

[0002] At present, the binding and pressing of the LCD panel module can be realized by automatic machine calibration, but there is still a phenomenon that the driving circuit (for example, the source driver) and the gold finger pressing are deviated, which causes the LCD panel module to fail when it is powered on. The drive circuit may be short-circuited and burned
Although the existing solutions are designed to prevent binding and pressing deviation, for example, adding two test points on both sides of the pressing metal finger, in practical applications, it is only possible to test whether the liquid crystal panel module is binding and pressing deviation. Shifting, unable to prevent the drive circuit from short-circuiting and burning

Abstract

The invention relates to a display driving device, a display screen and a short circuit prevention method. The device comprises a display interface and a control panel, wherein the display interface comprises a plurality of display driving devices at fixed positions and a first interface module; the control panel comprises a control module and a second interface module; the control module is electrically connected with the second interface module; and the display driving devices are electrically connected with the first interface module and the second interface module in series to form a series link, so that when any display driving device deviates from the fixed position, the control module controls the series link to be disconnected. According to the display driving device, the display screen and the short circuit prevention method disclosed by the embodiment of the invention, the series link can be controlled to be disconnected when any display driving device deviates from the fixed position, so that the plurality of display driving devices are prevented from being burnt due to short circuit.

Description

technical field [0001] The present disclosure relates to the technical field of circuit protection, in particular to a display driving device, a display screen and a method for preventing short circuit. Background technique [0002] At present, the binding and pressing of the LCD panel module can be realized by automatic machine calibration, but there is still a phenomenon that the driving circuit (for example, the source driver) and the gold finger pressing are deviated, which causes the LCD panel module to fail when it is powered on. The drive circuit may be short-circuited and burned. Although the existing solutions are designed to prevent binding and pressing deviation, for example, adding two test points on both sides of the pressing metal finger, in practical applications, it is only possible to test whether the liquid crystal panel module is binding and pressing deviation. shift, it is impossible to prevent the drive circuit from being short-circuited and burned.
