How to verify the last step of TFT?

It's because I didn't have the link in my hand at the time.,You can try again by following the steps below.。

3. Click on iTunes Stores, find a free app on the left border, and click to enter;

4. Click "Free App" in the interface - click "Create New Account" - click "Continue" - check "I have read and agree to the above terms and conditions", and then click "Continue";

5. Enter your email address, password, password Q&A, birthday (age greater than 18 years old) and other information, and click "Continue";

6. Payment card options (visa, master, express and none) will appear at the top of the interface, if you don't want to buy the payment program, select "none", then complete the following information (address**, etc.), and click "continue" when you are done

7. Apple will send a confirmation letter to your mailbox, and you can click on the ** link in the mailbox to activate.

First write css, write a class in the case of an error, name it such as onerror, and then use if else in jquery to judge each event, return true when it succeeds, write a current error message errormsg whenever it enters an error, and then $ the current focus. $''+errormsg+'

This is to append a span prompt label after the unsuccessful part, and finally return false. In the final verification, all these events are committed, and if true, they are not committed.

The size of the viewing angle, tilt the phone left and right and then visually inspect, if the discoloration is severe, it is TFT, and if the discoloration is light, it is the IPS screen.

If there is no problem with the program, it means that there is a problem with the wiring, and the first contact is not good.

TFT-LCD stands for thin-film transistor liquid crystal display. Its full name in English: thin film transistor-liquid crystal is different from the simple matrix of passive TN-LCD and STN-LCD, it is provided with a thin film transistor (TFT) on each pixel of the liquid crystal display, which can effectively overcome the crosstalk when it is not gated, so that the static characteristics of the display LCD screen are independent of the number of scanning lines, so the image quality is greatly improved.

TFT-LCD is also known as true color liquid crystal display.

1. Two sizes of screens are optional.

2,320 240 resolution.

3, 16-bit true color display.

4. Comes with touch screen, which can be used as control input.

5. Universal interface, in addition to Alientek MiniSTM32 development board, the LCD module can also be used on excellent special, STMSKY, Red Bull and other development boards.

In this section, we take the Alientek TFTLD module as an example, the module uses DST2001PH TFTLCD of Xianshang Optoelectronics, the controller of DST2001PH is ILI9320, and the TFTLCD screen of 260,000 colors is used, the resolution is 320 240, and the 16-bit 80 parallel port is used.

SLCD and TFT are put together, and SLCD is obviously much more gorgeous.

The appearance is unrecognizable and cannot be verified. The power-on can be compared to the power consumption, and the display with LED backlight consumes less power.

Yes, turn on the display and you will know whether it is an LED backlight or a fluorescent tube backlight.

The LED screen is thin and has no tubes. The LCD screen is slightly thicker and has a light tube.

It mainly depends on whether there are lights, some are LCD, and what is not is LED

Try a different computer. I used to be like this, and I was able to register on a different computer and succeed immediately.

As long as you take a picture of the smallest ** and the largest **, multiply their length and width, for example, the smallest **size of my mobile phone is 240*320, this is the screen size, the largest** is 1600*1200, this means that the mobile phone is 2 million pixels.
