Use and Maintenance lcd module

Use and Maintenance lcd module
1. When using an access lcd module and disconnect the power supply must be (5 ± 0.25V) to the input signal level at the positive.
2. The dot matrix modules are high large ones lcd display a great contrast, viewing angle and temperature, drive voltage relationship.
3. When the specified operating temperature range limit use, displays the response is very slow. In the specified operating temperature range of the upper limit using the entire display surface becomes black, this is not damaged, the recovery temperature range, can return to normal.
4. Firmly press the display section, will produce abnormal display, just turn off the power, re-access can be restored.
5. The liquid crystal display device or module surface fogging, do not power work, because then the electrode from a chemical reaction, producing breakage.
6. Long-term cover for being the site will produce residual images when the sun and bright light.

LCD display

The number of modules LCD display LCD module is the most common, which is assembled from a segment type liquid crystal display device with a dedicated integrated into one functional unit can only display a number of identification numbers and symbols. Segment type lcd modules are mostly used in the portable, pocket-sized devices, as these devices are small, so as not to show part of the design into separate parts.

LCD module classification

LCD module has three types: character LCD module is a module with a Chinese font, font can be displayed in any of the characters; graphic lcd display module are arranged in a desired pattern by dot matrix symbol, of course, also possible to form text characters, letters, etc. as a graphic editor, but it needed to be bigger microcontroller space; field type LCD module LCD screen in a fixed number of characters, such products are generally used for fixed devices, such as telephones, electronic watches, vcd display section.

OLED application

OLED display module technology has a self-luminous display module characteristics, using a very thin coating of organic materials and glass substrates, when a current is passed, these organic materials will be light, and OLED display viewing angle, and can save energy, from 2003 began this display device in the MP3 player has been applied. OLED organic light-emitting material used, the one with dye and pigment material is a small molecule device system, and the other places conjugated polymer is a polymer material, the device system.

Backlight Profile

The so-called backlight is a light source located in a liquid crystal display (LCD) behind the LCD panel to provide a light source, it will directly affect the glow LCD module (LCM) visual effects. LCD itself is not light, it displays graphics or character is its light modulation results. With the continuous development of LCD technology, liquid crystal display applications especially color liquid crystal displays are continuously expanding.
