Abstract

The present application provides a display device, a chamfering resistance circuit and an implementation method thereof. The chamfering resistance circuit comprises a first area disposed in a fan-outarea of the display device, the first area comprises M1 cascaded first resistors, an input end of a first resistor is an input end of the first area, the input end of the first area is connected to adischarge signal, the output ends of the I1th to the M1th first resistors are jointly connected to form an output end of the first area, and the output end of the first area is grounded, wherein I1 isnot smaller than 1 and not greater than M1, and M1 and I1 are integers. In the present application, according to a resistance value required for chamfering gate voltage, a chamfering resistance circuit composed of a plurality of resistor strings in series and parallel is disposed in the fan-out area of a printed circuit board of the display device to realize a gate voltage chamfering function, sothat batch control of all resistors can be realized, and component cost and packing cost of setting resistors on the printed circuit board can be saved.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a display device, a chamfering resistance circuit and a realization method thereof. Background technique [0002] With the continuous development of science and technology, various display devices emerge in an endless stream, bringing great convenience to people's production and life. For example, TFT-LCD (thin film transistor-liquid crystal display, thin film transistor-liquid crystal display) is one of the current main types of display devices and is widely used in various display products. TFF-LCD mainly transmits the three primary color compression signals, control signals and power signals to the TCON (Timing Controller, Timing Controller) chip set on the PCB (Printed Circuit Board) through its system main board. The S-COF (Source-Chip on Film, source driver chip) and G-COF (Gate-Chip onFilm, gate driver chip) set on the PCB are processed and output t...
