　　CRT monitor CRT monitors need to be aware of the following issues in their daily use: 1.CRT monitors should be aware of moisture, long-term use should also be regularly energized to disperse the moisture in the monitor. 2. Adjust the brightness and contrast of the display, so that the screen display is not too bright, to avoid the rapid aging of the picture tube. 3.CRT display should be away from the magnetic field, lest the picture tube magnetization, appear jitter, flicker and so on. 4.

At present, the general color LCD connection mode has so many: MCU mode, RGB mode, SPI mode, VSync mode, Mddi mode and so on. ========================================================================================= First, the hardware interface MCU mode: currently the most commonly used connection mode, usually 80 system (68 system no longer exists). Data bits are transmitted in 8-bit, 9-bit, 16-bit, and 18-bit. The connection is divided into: cs/,rs

It has always been known that EFM32 LCD Controller supports simple animation effects without MCU involvement. However, there is no time to summarize this function. Take the time to sum up, so on the basis of tg stk, a detailed description, so that you do not have to forget for a long time. The final effect is as follows: Note: Gecko is not displayed completely because I disconnected PE13. Used to test EM4 GPIO wake-up. The

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 limited viewing angle, slow response speed, and we

LCD computer monitors can not adjust the brightness, or after the adjustment will flicker, with a long time will also blink, but sometimes back to normal. Voltage or surrounding electrical appliances may cause the LCD screen flicker, at the same time the internal contact is bad or high pressure plate problems will cause the above phenomenon. When this happens, the display can be moved elsewhere, and

How to set up a notebook external flat panel monitor? The method steps for setting the details are as follows: The output frequency of the notebook does need to look at the performance of the video card of the notebook, but the more decision of this refresh frequency is the screen itself, the LCD is mainly divided into two kinds of standard 6 hertz, and the other is the Nvidia 3D display which is required by 120 Hertz screen Support, and need to supp

LCD panel is the LCD TV screen, its output, quality and market environment, and many other factors are related to the quality of the LCD display itself, price and market trend, because a liquid crystal display its cost of about 80% are concentrated in the panel. The quality of LCD panel, technology is also related to t

1, what is LCD?(1) LCD (Liquid Crystal Display) is commonly known as liquid crystal. Liquid crystal is a material, liquid crystal This material has a feature: can be driven under the electric signal of the liquid crystal molecules to rotate, the rotation will affect the light transmittance,So we can use the whole LCD panel behind the white Light (called backlight

As long as the digital signal processing circuit, there must be a clock signal. In the LCD panel, the pixel clock is a very important clock signal. The frequency of the pixel clock signal is related to the working mode of the LCD panel, the higher the resolution of the LCD panel, the higher the frequency of the pixel clock signal. Within a row, the number of pixe

In the CRT era, screen flicker is a common fault, usually caused by insufficient refresh frequency of the display card. Many users do not know what the refresh rate is, plus the system default is 60 Hertz, many users often use a lot of years low refresh rate to understand the CRT screen can not flicker. To the liquid crystal display era, environmental protection without radiation, and no flicker and other features become the biggest selling point of liquid crystal display. However, some users

This LCD module is composed of Liquid Crystal Display controller T6963C and its peripheral circuit, Row drive t6a40 group, Column drive t6a39 group, LCD Drive bias c

First, the principle of LCD hardware The display LCD made of liquid crystal can be divided into static drive, simple matrix drive and active matrix Drive 3 according to drive mode. The simple matrix type can be used to differentiate the torsional column type (TN) and the ultra-torsional type (STN), while the active matrix is the mainstream of the thin-film transistor type (TFT).A piece of

1. Hardware requirements for LCD: To make an LCD display of text or images normally, not only the LCD driver, but also the corresponding LCD controller. Generally, the manufacturer makes the LCD driver in the form of cof/COG together with the

The liquid crystal display has radiation, but it is very low. The principle of radiation is that the current generates a magnetic field to generate an electric field and then generate a magnetic field, so that the infinite cycle of its source is the current so as long as there is radiation, but there is no ordinary display LCD display high-voltage coil, so the radiation is very low. LCD Bi Chunping Moni

References Before debugging: 1) debug the LCD backlight. The backlight is mainly divided into the built-in PMIC and the independent dcdc. If the backlight is the built-in PMIC, the general platform vendor has done a good job and can directly call the interface, if the driver is a separate dcdc driver, you need to use gpio to control the dcdc's en end. 2) check whether the analog and I/O power of the LCD are

It is well known that the LCD (liquid Crystal display) LCD screen used by laptops has many advantages, such as "low power, no radiation, no dizziness" compared with the CRT (cathode ray tube) Cathode ray tube display used by most desktops, And to a large extent to protect the user's eyesight. But in the display family, LCD can be counted as a noble miss Jiao, it
