Abstract: A color filter substrate and an organic light-emitting display panel are disclosed. The color filter substrate is rectangular and has an upper side, a lower side, a left side, and a right side, wherein, the lower side corresponds to a driving chip of the organic light-emitting display panel. The color filter substrate includes a light-shielding layer defined with a plurality of light-transmitting holes arranged in an array, and from the upper side to the lower side, openings of the light-transmitting holes are gradually smaller. The present disclosure allows an aperture ratio of the light-shielding layer to be gradually reduced from the upper side that is away from the driving chip to the lower side that corresponds to the driving chip. Therefore, an area of the organic light-emitting display panel having uneven chroma and brightness can be compensated, thereby improving uniformity of the chroma and brightness.

Abstract: A gate driving circuit and a display panel are disclosed. A pull-up control module and a pull-down module of each stage gate driving unit are connected to a first node. A thin film transistor in the pull-up control module and/or pull-down module that is connected to the first node is an oxide thin film transistor, such that a leakage current of the first node is reduced due to the advantage of the small off-state leakage current of the oxide thin film transistor. Therefore, the voltage level of the first node can remain stable during a pull-up stage and a touch suspension stage.

Abstract: A display panel and a gate driving circuit are provided. The gate driving circuit utilizes the pull-down control module to periodically pull up and pull down the voltage level of the second node. The voltage level of the second node is periodically a high voltage level. This effectively reduces the time duration when the second node corresponds to the high voltage level. After the TFTs electrically connected to the second node are forward biased, the TFTs could have sufficient recovery time. This solution effectively improves the bias condition of the TFTs in the pull-down control module and thus makes the circuit more stable and raises the reliability of the circuit.
