摘要: The present disclosure discloses a backlight driving circuit and a display device. The backlight driving circuit includes a power supply chip, light-emitting diodes connected to the power supply chip, and a voltage protection sub-circuit connected to both the light-emitting diodes and the power supply chip. By adding the voltage protection sub-circuit, when a negative terminal voltage of the light-emitting diode is abnormal, the voltage protection sub-circuit will output a feedback signal to the power supply chip to stop the power supply chip from working, thereby improving reliability of the backlight driving circuit.

摘要: The present disclosure relates to a top emitting AMOLED display panel, a manufacturing method thereof, and a display device. The top emitting AMOLED display panel includes a passivation layer and a protective conductive layer. The passivation layer is sandwiched between an interlayer insulating layer and a planarization layer of the top emitting AMOLED display panel; the protective conductive layer covers a metal layer and side walls of openings. The passivation layer covering the metal layer can physically protect and prevent the metal layer from oxidation, and the protective conductive layer coats the metal layer to prevent the metal layer from being etched or oxidized by anode etching solution.

摘要: The present disclosure provides a precursor solution of an indium gallium zinc oxide film and a method of preparing an indium gallium zinc oxide thin film transistor. The precursor solution is provided with an indium salt, a gallium salt, a zinc salt, a stabilizing agent, and a solvent. The stabilizing agent is ethanolamine. Use of ethanolamine helps to promote an oxidation process of the precursor solution, and reduce an oxygen vacancy concentration in the indium gallium zinc oxide film, so as to improve negative bias of a threshold voltage of a channel layer made of the indium gallium zinc oxide film in a thin film transistor.

摘要: A gate driving circuit and a display panel are provided. The gate driving circuit reduces the number of transistors through the inverter in the pull-down maintaining circuit such that the number of the signal output ends connected to the inverter is reduced. In this way, the number of the other transistors in the pull-down maintaining circuit is also reduced. Therefore, the number of the transistors and the number of the signal output ends of the pull-down maintaining circuit are both reduced. This means that the number of the transistors and the number of the signal output ends of the gate driving circuit are both reduced.
