Abstract

The invention discloses a panel driving circuit and a display panel, and the panel driving circuit comprises a control panel and a plurality of driving modules. The control panel is provided with a plurality of first connectors and a plurality of first anti-oblique-insertion protection circuits, and each first anti-oblique-insertion protection circuit is connected with the first connector at the corresponding position or arranged on the first connector at the corresponding position; each driving module comprises a driving circuit board and a plurality of driving chips, the driving circuit board is connected with the plurality of driving chips, each driving circuit board is provided with a second connector and a second anti-oblique-insertion protection circuit, each first connector is connected with the second connector at the corresponding position through a cable, each second anti-oblique-insertion protection circuit is connected with the second connector at the corresponding position or is arranged on the second connector at the corresponding position; and the first anti-oblique-insertion protection circuit and the second anti-oblique-insertion protection circuit are used for protecting the driving chip when the cable is obliquely inserted. According to the invention, irreversible damage to the display due to poor wire plugging can be avoided.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a panel driving circuit and a display device. Background technique [0002] In current liquid crystal display (Liquid Crystal Display, LCD) products, two circuit boards, the control board Cboard and the screen horizontal direction scanning driving board Xboard, are connected through a flexible flat cable (FFC). [0003] see figure 1 , figure 1 It is a structural schematic diagram of a panel driving circuit in the related art. During production, the FFC wire is connected to the connectors (Connector) of the scanning driver board Xboard and the control board Cboard in the horizontal direction of the screen. , COF) chip ((Integrated Circuit, IC) burns out. [0004] see figure 2 , figure 2 It is a structural schematic diagram of an internal power supply circuit of a chip-on-chip thin film chip in the related art. When there is an oblique insertion, the...
