Notebook Use time long screen will be aging, the image is not clear, color inequality. This is the result of the aging of the LED display, which marks the aging of the LCD screen. Here are a few ways to slow down the screen of the laptop to turn yellow and aging: Minimize screen brightness: When working in a notebook computer, you can set the brightness of the screen to 2~3 brightness, to extend the screen life, but also to protect eyesight; You can

The DEMO4,LCD CLK interference I2C,I2C cannot communicate.Press the pin down to remove the CLK from the LCD and return to normal. Process: Direct jumper i²c, no problem. Two rows of pin are not able to communicate together. A row of needle removal, and finally found the LCD CLK line.and I²c side-by line, causing interference. Solution: Add a resistor to the LCD's

At noon on Saturday, I still came to the company and didn't intend to come. Now, let's solve some of the problems left over from the last time, let's sum up the pwm LCD Backlight for Android. The backlight of Android is controlled by PWM wave. Different voltage values are obtained through different duty cycles, so that the brightness of the LCD is different. Specifically, it controls the voltage value. To a

Burning screen before the phenomenon mainly occurred in plasma TV, now some LCD display also has a burning screen phenomenon. Burning screen refers to the permanent display of an image when the LCD display displays a still image for a long time, resulting in permanent imprinting. Correct use of LCD display, even if the performance of a better display is not long

Install Windows Optimizer Master, there is no requirement for selecting a standard or Professional edition. Run the program, switch to the "system detection → video System Information" column, the right pane will display including video card, display, supported display mode, video drive performance and other items, we need to pay attention to the contents of the "monitor". View basic information for the LCD screen Here you can see the

Content Summary:At present, the general color LCD connection methods have so several: MCU mode, RGB mode, SPI mode, VSync mode, Mddi mode. MCU mode: Currently the most commonly used connection mode, is generally 80 system (68 system no longer exists). Data bits are transmitted in 8-bit, 9-bit, 16-bit, and 18-bit. Lines are divided into: cs/,rs (Register selection), rd/,wr/, and then the data line. The advantages are: simple and convenient control, no

I plan to analyze the specific call process from the application call. This is the core of our understanding of the driving framework, rather than simply accepting it. 1. Analysis of driver core fbmem. C (Alps \ kernel \ drivers \ video \ fbmem. c) The following is a part of the source code, including the entry

Author: gooogleman@foxmail.com I slept a lot today, so I started debugging with sate210 with VGA work control board tonight, because I saw that the P clock and parameter standards were not very high, so I thought, the maximum LCD pixel clock of s5pv210 is 166 m, so it fully meets the 1080 p 1920*1080 resolution requirements. So I filled in the parameters according to the standard and modified the related clock PARAMETERS OF THE sate210 wince system, O

After checking the following information on the Internet, some LCD screens are similar to plasma TVs. Unfortunately, my display found this problem yesterday. Fortunately, it is not a permanent injury, and it can be recovered after a period of rest. The solution is to enable the monitor only when necessary. In addition, make sure that your operating system is in power-saving mode and the time is set to 10 ~ After 15 minutes, you can take a break when

Recently I want to upgrade my TV, so I want to buy a 46 (47) TV. I have locked several models on the Internet. Today I went to Suning and Dazhong and Gome to see the actual results, I would like to share with you that everything is my subjective feeling and the feeling of a batch of prototypes I have seen. So only one reference is provided. Source of the test: 1. 720 p MKV format x264 embedded subtitle cartoon aptx Conan. 2. h264 1080 p Deep Blue 3, h264 DTS 1080p ye Wen, 4, rmvb format P movie

I bought it for one day, but I don't feel much about it: 1. it saves a lot of space than CRT. My big table is one meter wide and the original aoc17-inch makes up most of the table width, the LCD now accounts for 1/4 of the table width, freeing up most of the space to put a tablet, there are a lot of messy lines; 2. the screen is mostly used, and the standard resolution is 1280 × 1024. The word is too small, and the display is far away. The resolutio

I bought a beautiful us 5820 LCD TV box a year ago. I checked a lot of related information on the Internet before I bought it. I don't feel very objective. It seems that something is good. I only know it when I use it. After using it, let's talk about my real experiences for the reference of people who are interested in buying it. I am using a 19-inch LCD (youpai va912).
