The proposed LCD sketch and instructions sent to at least three suppliers

1. Consider what needs alphanumeric LCD useful information and customization required in combination with a custom icon is displayed on the custom LCD.
2. Learn LCD need to work environment. Operating voltage and temperature will greatly affect the LCD contrast, and may limit the LCD type can be used.
3. Determine the number of Character LCD Modules segments required to achieve the necessary display on the LCD, and the reference matrix LCD PIC microcontroller to select the appropriate LCDPIC microcontroller.
4. Generate customized LCD sketch / mechanical drawings and written instructions and understand LCD pinout.(Due to the wiring section and the wiring electrode of the common electrode is not a limitation of this plane, and therefore, is preferably accomplished by the display manufacturer pin arrangement.)5. The proposed I2C Lcd Display LCD sketch and instructions sent to at least three suppliers, obtain written quotations to determine pricing, scheduling and quality matters. The total NRE cost, price and installation costs into account. Allow at least two weeks time for the completion of formal mechanical drawings and pin assignments, as well as the revised drawings.6. Request Delivery initial prototype LCD components to ensure proper development of LCD and correct functioning of the target application.Usually set aside four to six weeks time. For final approval mechanical drawings and pin assignments. After the delivery of the initial prototype LCD approval.7.Upon receipt of a prototype LCD, first confirm its function, and then make the final approval and began producing LCD.

the light transmitted through the LCD screen in our eyes

OLED display module simple point that is screen, backlit panels, PCB board, iron box. Power terminal, instruments and other display components is oled display module, its status is equivalent to the CRT tube. OLED display module is divided into screen and backlight lcd graphic display components. The two parts are assembled together, but when the work is independent. Principle OLED display module is the backlight unit issued uniform surface light, the light transmitted through the LCD screen in our eyes. Role OLEDdisplay module panel is light in pixels of the I2C Lcd Display processing to display an image. OLED display module manufacturing selected control IC, filter and directed film accessories. Contrast is very important, arguably a more important indicator than the highlights of selected LCD, when you know your customers to buy the LCD is used for entertainment watching DVDs, you can emphasize the contrast is more important than no dead pixels, we look at when streaming, the general brightness sources for little, but to see chiaroscuro character scenes, gray hair texture changes to black, to rely on the level of contrast to visualize the.

LCD module simple point that is screen and backlight components. LCD TV display unit is a liquid crystal module, its status is equivalent to the CRT tube. The other part includes a power supply circuit, a signal processing circuit, etc., and of course the housing or something. The main screen is divided into modules and backlight components. The two parts are assembled together, but when the work is independent of (i.e., the circuit is not relevant). Principle of LCD backlight unit is uniform surface emitted light, the light transmitted through the LCD screen of our eyes. The screen in pixels is the role of these light processing to display an image. When the liquid crystal panel manufacturing selected control IC, filters and accessories directed film, the contrast with the panel about the relative CRT monitors easily reach 500: 1 contrast ratio even higher in terms. Only high-end LCD monitors in order to achieve this such an extent. LCD is a substance that is between the solid and liquid itself is not light, and requires the use of an additional light source to the job. Therefore, the relationship between the number of lamp LCD monitor brightness. The first LCD monitor only down two lamp, to the present, universal minimum is four lights, high-end six lights. Four lamp design placed into three forms: one is the four sides each have a lamp, but the drawback is in the middle there will be shadows, the solution is on the way from the lower level of the four lamps arranged, the last one is placed in the form of a "U" is in fact a disguised produced two lights two lamps.

This phenomenon is usually the problem of the PCB

To troubleshoot, first of all have a certain understanding of the module, so that repair from the module in order to play a multiplier effect.
<1> troubleshooting prerequisites:
① assembled to master certain lcd module skills, mastered certain skills in troubleshooting, can be handy, reduce assembly problems.
② To constitute modules have a certain understanding. A module, in order to have good electrical display, shell, screen, zebra, PCB board must be designed, qualified raw materials in order to receive good results. Such as: zebra compression ratio enough, resulting in lack of planning, this situation is repeated assembly, reliability display lcd 16x2 does not work, then we should change the zebra.
③ To the assembled modules to the principles of the modules have some understanding of the problem so that after assembly of the module will be targeted. Such as: When on a PCB, chip pin control panel two SEG electrodes, once discovered missing two SEG symmetry appears on the module, it can be concluded that the problem of the PCB
Semi-deep half-light, do not walk, program exceptions, less of a screen or a few screen when not in tune, there are shadows, etc. This phenomenon is usually the problem of the PCB, you need to remove the PCB test PCB board. Reassembly with a good PCB board.
