qvga lcd module made in china

Monochrome lcd panel is low cost LCD screen, monochrome lcd display is the mainstream in custom lcd screen because its custom tooling fee is very cheap.Monochrome LCD display included standard graphic monochrome lcd display, character lcd module, monochrome segment lcd display, monochrome tft lcd module and custom lcd screen.The monochrome lcd screen structures have COG LCD (chip on lcd glass), COB (chip on board), COF (chip on film).

An seven segment lcd display is like the below picture, it can display numbers from 0 to 9 and several letters such as C, A, b E, L, and F by control some segments "on" and "off". it is the cheapest lcd display panel.

The segment lcd also could be in Icon lcd display, that is the display content are the custom segments based on customer"s application.each segment means one icon, we could design the icon on our application.

The familiar Characters lcd modules have 16x1, 16x2, 16x4 characters, 20x1, 20x2, 20x4 characters, and 40x2, 40x4 etc, characters lcd display module. An 16x2 lcd display means 16 characters x 2 lines character on the lcd. normally, one characters is made by 5x8 pixels, we could display numbers 1~9, and A~Z letters and most of characters on the 5x8 pixels per characters.

The standard graphic lcd resolution have 96x64、96x96、122x32、128x64、128x128、160x128、160x160、192x64、240x64、240x128、320x240 etc.we could display all the characters and image in the graphic lcd display. of course, the higher resolution lcd, the display effect of image would be better.

(What is lcd resolution: )Lcd resolution means how many pixels of lcd screen,128x64 lcd resolution means 128 column x 64 row pixels on the lcd screen, we also call it 128x64 lcd display. monochrome lcd resolution could be 320x240 (QVGA) or 480x240 maximum, tft lcd resolution could be VGA (640X480) or HD (1366x768, FHD(1920x1080) or 4k2k lcd resolution.

Yes, if you only need the low quantity monochrome lcd display for your project, you could choose Maclight standard monochrome lcd, Maclight have wide range standard Characters lcd and Graphic lcd module, including COB type and COG type for your choosing. please find the standard monochrome list in the end of article, welcome to contact Maclight at [email protected]

The tooling fee of monochrome lcd panel would be around 300~500 USD, if only the simple segment lcd panel, such as TN display mode, then tooling fee would be cheaper, but if the custom lcd screen is monochrome graphic lcd panel, such as STN display panel, the tooling fee would be little higher than TN lcd panel. because the tooling mask for stn lcd would be higher than TN lcd panel. but it is only the tooling fee for monochrome lcd panel.

If for custom monochrome lcd module that with IC chip on glass, we call it COG LCD module, the tooling fee would be more higher, because if for custom TN or STN lcd display panel, the tooling mask can be made by PI film, while for custom monochrome COG LCD module, the custom COG LCD tooling mask would be used the metal mask, the tooling fee would be more higher to around 1500~2000 USD.

Besides the custom lcds panel, for some custom lcd mode that in transmissive lcd or transflective lcd display mode, because lcd panel is passive display, instead of oled display, lcd panel can not emit light by itself, it have to use the backlight, the backlight tooling fee would be upper than 1000 USD or more, the more complicating structure on the backlight, the tooling fee would be higher. for saving the cost of tooling fee on lcd backlight, the simple structure would be cheaper.

The MOQ of custom lcd display for monochrome lcd is calculated based on the mother-glass of LCD panel, some person may ask, what is mother-glass of lcd panel? is it the mother of lcd panel? no, no,no..., it is just a joke, the mother-glass of lcd is the primary glass of lcd, we also call it ITO glass, because it have an ITO layer on the glass. the lcd panels are array on the mother glass in manufacturing lcd panel, and cutting it one by one after lcd cell production finished. the main mother glass sizes if 14"x16", as in lcd manufacturing, for stable running in the full-auto machine line, it is at least 50 set of 14"x16" for an production running, that is the smaller sizes of lcd, the bigger MOQ of lcd quantity is necessary.

1. Confirm the sizes what you would like to custom making? the custom mono lcd displays would be mainly less than 10", the custom sizes is up to the mother glass of lcd panels that is less than 14"x16". the custom mono lcd can be custom made the random sizes below 10".

If you would not like to custom lcd display, you could choose the standard lcd from the following list, it is no MOQ requirement for the standard lcd.

Monochrome lcd display have TN, STN LCD, monochrome tft lcd types. the monochrome lcd could be with or without backlight. even for monochrome lcd display, it have difference LCD colors for choosing, such as yellow-green mode, blue mode, gray mode, black-white mode, negative display mode and positive display available. the backlight color could be white, green, orange, yellow-green colors.

OLED has a lot of advantages like simple structure, ultrathin, self-luminescence, high brightness, short response time, wide viewing angle, low operation voltage and so on, which is widely applied in cell phone, PDA, DC, on board display and military field. This paper represents a real-time video display system on OLED based on the detailed analysis of OLED panel electrical characteristics and various gray scale scanning principles of the OLED scan and drive circuit. FPGA is the core control device in the whole system, the DVI decoded signal is processed and real-time displayed on the OLED. 240×RGB (H)×320 (V) QVGA, 256 gray scale is implemented and frame frequency is 60Hz~100Hz. The power drive has 7 outputs, which is adjustable to fit the external environment. Among them, sub-field scanning working mode is adopted in the design, gray scale is selectable.
