Abstract: Provided are a capacitance detecting circuit, a touch control chip, a touch detection apparatus and an electronic device. The capacitance detecting circuit, by configuring a first input side of an operational amplifier as a preset voltage, and utilizing the same characteristics of voltages at two input sides of the operational amplifier, enables that an output voltage in a touch sensor is configured as a preset voltage by a second input side of the operational amplifier, and by changing a position of a drive of a coding voltage, mutual-capacitance and self-capacitance detection can be realized with the same circuit. After replicating a single-channel current signal output by the operational amplifier into a multi-channel current signal, a current subtracting circuit is used to determine a differential signal of current signals output by two adjacent channels, and the differential signal is converted into a voltage through a charge amplifying circuit.

Abstract: A color filter, a display panel, and a display device are provided. The color filter includes a substrate, a plurality of color resistors, and a color blocking layer. The plurality of color resistors are arranged in a matrix on the substrate. Two adjacent color resistors have an interval in-between. The color blocking layer is placed in the interval. A transparent structure is placed on each of the color resistors. This could reduce the transmission loss of the light and thus raises the incident/outgoing light efficiency.

Abstract: Disclosed is a hooking device of a VR data cable, configured to hang the VR data cable, including a buffer, a hang assembly, and an adjustment assembly. The buffer is hung on a hook of a ceiling. The hang assembly is configured to hang the VR data cable. One end of the adjustment assembly is connected to the buffer, and the other end of the adjustment assembly is connected to the hang assembly, and the adjustment assembly adjusts a hang height of the VR data cable through elastic expansion and contraction.
Abstract: Provided are an LDO, an MCU, a fingerprint module and a terminal device. The LDO includes: a reference voltage generating circuit and a source follower connected to the reference voltage generating circuit. The reference voltage generating circuit is used to generate a reference voltage that changes with temperature to offset a voltage change caused by a voltage between a first terminal and a second terminal of the source follower changing with time, so that an output voltage of the second terminal of the source follower does not change with temperature. The LDO omits an operational amplifier EA and a resistor divider feedback network in the prior art, which not only has a simple circuit structure, but also can achieve ultra-low power consumption.
Abstract: The application relates to the technical field of wiring accessories, in particular to a protective tube. The protective tube includes a tube wall and fluffy warp yarns, wherein the tube wall forms a pipeline for a cable to be threaded therein and includes cross-woven first warp yarns and first weft yarns; the fluffy warp yarns are on an inner surface of the tube wall and are fluffier than the first warp yarns, the fluffy warp yarns are cross-woven with the first weft yarns and form a plurality of intersections with the first weft yarns, and each of the fluffy warp yarns spans a plurality of the first weft yarns between two adjacent intersections. When the protective tube is subjected to external impact, the tube wall with stronger hardness can protect the cable; moreover, the fluffy warp yarn reduce the friction between the protective tube and the cable.
