How to identify the original color TV
As living standards improve, everyone on the brand and quality appliances are increasingly critical, while imports of household electrical appliances will naturally be more popular. But in the purchase process, consumers are buying is difficult to clearly identify whether imported appliances is original .TFT LCD
Displays By following highlights we will be better able to distinguish whether you purchase home appliances original products .
First , look on the box is printed with the trademark or brand , its upper right corner or small fonts printed on the bottom right corner of the word , and only after the registration of the company recognized the quality of products , the right to use this package , while the cottage or counterfeit there will not be such a logo. Meanwhile, in the electrical back cover will usually be clearly identified producing countries ( such as Japan MadeinJAPAN) or production areas ( such as Hong Kong manufacturing MadeinHongKong), through which identity can be distinguished in the local manufacturing or in the overseas subsidiaries. Some appliances not marked origin, can be checked by using the manual ,COG LCD Module if the instructions printed on the printing Home location can be determined that the product is assembled in the production .
Second, cottage or counterfeit often use to add, delete , change the way of foreign brands to imitate , and even that is a complete theft trademarks to cheat . At the time of purchase , the consumer must pay attention to the product packaging or instructions on the label which company produced , in order to confirm whether the company's products.

Chargers and common mode noise
Capacitive touch screen devices is a major problem is that the charger emits high-frequency noise intensity touch performance will decline. Some mobile devices plugged into the charger only provide limited touch capabilities, or connect the charger does not apply when the device can not use the charger display information, in order to cope with high noise charger issue. The best solution to say it is not perfect.graphic lcd
display module A quick look online forums and message boards related information, we can find a touchscreen device by charger noise problem is widespread and has made some consumers feel a headache.
Just as a standard USB charging interface rapid promotion in mobile devices, which also spawned a large number of low-cost aftermarket option market charger. Many chargers are more concerned about cost issues, without attention to performance, these chargers using inexpensive components, or the lack of common-mode noise can help reduce specific components.
The power and ground supply voltage with respect to ground voltage fluctuation, but between maintaining the same pressure, it will form a common mode noise. Such fluctuations only in the ground-coupled fingers touch screen that can affect the performance of the touch screen. Finger pressed with the same electric potential, mobile power and ground relative to its volatility will lead to noise injected by a finger touch screen. The amount of charge injected depends on the peak-to-peak voltage of noise.
In addition, the amount of the charge transport is also affected by two factors significantly affect: the fingers and the contact area between the touch screen and the touch screen overlay thickness of the lens.
The higher the capacitance, means injection of the touch screen, the greater the noise. In this case, the capacitance of a parallel plate is formed on one side by the finger contact area, the other side of the reception by the touch screen sensor electrode. First, TFT Display Module with the finger in contact with the touch screen area increases, the capacitance also increases accordingly proportional. However, since the receiving electrode from extremely narrow row or column form, the actual function of the diameter of the fingers.
