This is a lot of customers in the choice of monochrome screen is more unable to find the direction, how to choose the right monochrome screen is a question for many people, because there are many types of monochrome screen, cog, cob, etc., and when to use TN when to use stn, etc., the following will give you an introduction.

According to the display content to choose monochrome screen

1. Clear Product Positioning

First of all, customers should be clear about their product positioning, is to go in the high-end market or low-end market, if it is the low-end market, we can basically lock the TN and HTN two modes of selection, these two modes are in the monochrome screen price is the lowest, cost-effective, the only drawback is that the perspective range is relatively narrow. On the contrary, if the product is in the high-end market, then we have to choose in the FSTN and VA, the biggest advantage of these two is the wide range of view, basically close to the full-view contrast high, their only drawback is the high price.

2. Determine The Display Content

① Our display content is basically fixed display content, can change the part of the number of changes, and the icon and text part of the only two options to show and not show.

② display content for letters and numbers, then we need to display the number of letters or numbers per line to select the corresponding character dot matrix LCD module, such as the commonly used 1602, the display is 16 letters or numbers per line, a total of 2 lines, the same commonly used and 0802, 2002, 2004, etc. LCD module

③ display content for editable patterns, Chinese characters, letters, numbers, etc., and can achieve the function of turning the page, this kind of need we say the graphics dot matrix module, the number of commonly used dot matrix 12864 that is 128 columns * 64 lines, the same reason there are 19264, 240128, 24064, etc., the larger the number of dot matrix display more content, the same size dot matrix more display content more delicate

According to the product display effect to choose monochrome screen

LCD screen simply speaking, there are only two kinds of display effects: positive display & negative display.

① The difference between positive and negative display

Positive display fonts are dark, and negative display fonts are transparent (that is, the color of the backlight), and the product base color positive display base color for the color of the backlight, while the negative display base color has a blue background and a black background of two. Here we take the white backlight as an example to see the final display effect of different modes of LCD screen.

TN and HTN positive display FSTN positive display are white background black, the biggest difference between these three is the view range, TN is the narrowest view range, HTN slightly wider, while FSTN view range is the widest.

② HTN and STN negative display, both white characters on a blue background, the same difference between them HTN perspective is narrower, while STN perspective is wider.

③ TN negative display and VA, both white on black, because the TN negative display perspective range is too narrow, the final effect of the bottom color is not black, reddish, high-end products are not recommended. VA products are currently the highest contrast in the monochrome screen (white on black), the widest range of view negative display products. Mostly used for home appliances, energy storage power, smart home and so on.

④ STN positive display products, the display effect for the yellow and green background black (blue and black), and STN positive display gray film display effect: white background blue characters. Relatively niche. The above effects are white backlight display effect, different backlight display effect only need to replace the above white part of the color can be. In addition, the negative display products, display pen section can add silk screen in order to achieve a variety of color display effect, more used in VA products
