The above picture is the backlight driver circuit diagram of a display screen (AUO M190ETN01.0 ,19") I designed before. This article is going to take this as an example to explain how to design an LED backlight driver circuit and the related principles behind it. 1. Basic principle analysis Large-size display screens are currently mainly LCDs. The LCD itself does not emit light. If you want t...

With the improvement of the silicone product industry, many customized silicone gift processing will use the appearance pattern technology, some products choose mold printing patterns, while others choose pad printing processing or heat transfer printing. For soft silicone rubber products, what are the differences between thermal transfer and water transfer? Overview The appearance proce...

What is Qi protocol? Qi protocol is a wireless charging standard introduced by WPC. It is similar to the QC of Qualcomm. The QC protocol of Qualcomm tells the charger what Protocol I need by applying a certain voltage after listening to the data angle in the data line on the mobile 電話. The same is true for Qi protocol. When your mobile 電話 is put on, the transmitter and receiver of the charge...

Overview The principle of wireless charging is to conduct energy from the wireless charging device to the charging terminal device through near-field induction, and the terminal device converts the received energy into electrical energy and stores it in the battery of the device. The principle of energy conduction is inductive coupling, which can ensure that there is no exposed conductive interfac...

Servo motors are micro motors used as actuators in automatic control devices. Their function is to convert electrical signals into angular displacement or angular velocity of the shaft. Servo motor, also known as executive motor, is used as an actuator in an automatic control system. It converts the received electrical signal into angular displacement or angular velocity output on the motor shaft....

Radio controlled timepieces, also known as wireless control timepieces, are a new generation of high-tech products following quartz electronic clocks. The wooden alarm clock radios is a quartz electronic clock with a functional structure of receiving radio carrier signal, data processing, and automatic correction. In this way, it can receive the standard time signal sent by the ground transmitting...

Spraying has always been the most common surface treatment method for plastic housings of consumer electronics. In addition to creating the color and brightness that plastic dyeing is difficult to show, it can also provide higher hardness and abrasion resistance on the shell. In the beginning, when the shell progressed from plastic dyeing to spray painting, in order to get rid of looking cheapness...

The introduction of RGB The RGB color mode is a color standard in the industry. It obtains various colors by changing the three color channels of red (R), green (G), and blue (B) and superimposing them with each other. And RGB is the color representing the three channels of red, green, and blue. This standard includes almost all the colors that human vision can perceive, and it is one of the most ...

Humidity refers to relative humidity. Every time people gets the number from the weather forecast, the percentage to the relative humidity is a measure of air humidity. The lower this number is, the drier the air is, and the low to a certain extent, people will feel uncomfortable. Generally speaking, relative humidity can be understood as the amount of moisture in the air. In summer, the household...
