, in order to support 6-digit color display, 22 unencoded interfaces have signal lines before the shielding and/or multiple Ground Wires necessary to ensure signal integrity and anti-electromagnetic interference are added.Signal Encoding can simplify difficult and practical interfaces. At the same time, because of the encoding, manufacturers are prompted to select an encoding scheme, and the interface is more complicated. Several companies and organiz

To display the logo, of course, the first thing we need to do is to modify and improve the LCD driver. I will not go into details about the driver modification. I will search for it online, but I recommend it.Tekkaman ninjaIt is certainly okay to refer to his blog.

Q: What is LCD?The original text of the LCD display is liquid crystal display, which consists of the first letter of each word. The Chinese name is "LCD flat display" or "LCD
When you buy an LCD monitor, you should know that debugging them is completely different from the previous debugging of CRT monitors. If you do not know this matter, then hurry to follow me, step by step, the LCD to the best state it! Although these techniques are mainly for LCD, but some of them will also help the CRT, so still using CRT monitor friends, do not
STM32 practical application (I) -- 1602 Bluetooth Clock 1 LCD Display Test, 20171602Preface
After studying for so long from 51 to ikef4, I finally got a clue. Now I have learned the basic usage of GPIO, interrupt, timer, and watchdog, so I want to see if I can do something, I just want to review my recent knowledge. Last semester, I designed a single-chip microcomputer course with a clock that can be used f
With the popularity of LCD prices, many friends began to abandon CRT and choose LCD display. Compared with traditional CRT monitors, LCD monitors offer a slightly higher price, but have many advantages: no radiation, small size, low power consumption, beautiful appearance, etc, although there are problems such as limit
Analog Interface
The analog signal input to the TFT-LCD display device to show itself is a very ridiculous thing. The computer is running data, including image information, which is converted to analog signals on the display card, then transmitted to the monitor via the connector, and then displayed as a digital signal on the monitor, which is completely superfl
What is an LED? The LEDs are the initials of the light-emitting diode Lightemittingdiode. LED applications can be divided into two categories: one is led single tube applications, including backlight led, infra-red LED, and so on, the other is led display, at present, China in the production of LED basic materials and the international still have a certain gap, but in terms of LED display, China's desig

Transferred from: http://blog.csdn.net/changliang7731/article/details/53074616In the previous chapter, we briefly introduced some basic principles of LCD. And, of course, more esoteric, like gamma,dither,hue,satuation. OSD and so on.We know we are using framebuffer to achieve the display.Video memory: framebuffer. A portion of the RAM is drawn from the Ddram for video memory use.The operation of the LCD is
directly on the LCD OSD menu on the "Auto" button (some LCD is through the combination of keys to achieve the Auto button), the role is to let the LCD automatically adjust to make the text display more sharp. Of course, this is only useful for analog signals (VGA), if the user is using a DVI signal line, then its role
LCD LCD Monitor:LCD (Liquid Crystal Display), which is constructed in two parallel glass of liquid crystals (liquid crystal), behind the glass, to CCFL cold light tube (similar fluorescent lamp) as backlight. The liquid crystal imaging principle can be simply understood as, the external application of voltage so that the rod-shaped liquid crystal molecules change
