Product overview

Hongtai can provide LCD, LCM, TFT, BL and other products for you. The following is a brief overview of various products:


LCD (Liquid Crystal Display)

The structure of LCD is to place LCD cells in two parallel ITO glass substrates, and to attach polarizers to the upper and lower substrates. The rotation direction of LCD molecules is controlled by driving IC signals and voltage changes, so as to control the polarized light emission of each pixel point and achieve the display purpose.

The technical specifications of liquid crystal display (LCD) currently available by Xinhongtai Company are as follows:

Process types: TN, HTN, STN, FSTN and the latest VA full-view process;

Polarization mode: full, semi-transparent, reflective, RDF;

Thickness of glass: 1.1 mm, 0.7 mm, 0.55 mm and 0.4 mm not commonly used;

Pin spacing: 2.54 mm, 2.0 mm, 1.8 mm, 1.5 mm, 1.27 mm;

Maximum size: 395 mm X 345 mm;

Minimum spacing: 10 um;

Drive path: 1/320DUTY (duty cycle);

Maximum lattice: 640 x 320;

Voltage range: 2.5V~25V.


LCM (LCD Module)

The LCD module and LCD module refer to the assembly of LCD devices, connectors, control and drive peripheral circuits, PCB circuit boards, backlight, structural components and so on.

The technical specifications of liquid crystal display module (LCM) provided by Xinhongtai Company are as follows:

Process types: COG, TAB, COB (binding), SMT (patch), HEATSEAL (hot-pressed zebra paper);

Working temperature: room temperature 0 ~+50 C, wide temperature-20 ~+70 C, ultra-wide temperature-30 ~+80 C;

Interface types: 3-wire or 4-wire SPI serial port, 8-bit or 16-bit MCU parallel port, I2C, RS232 or RS485, USB interface;

Display mode: black characters on white background, black characters on yellow and green background, black characters on blue background, white characters on blue background, white characters on black background, customized screen printing color, etc.

Provide supporting: backlight, touch screen (digital, resistive, capacitive), various connectors, hardware and plastic shell.


TFT (Thin Film Transistor)

TFT refers to thin film transistors. Each pixel of TFT is controlled by TFT integrated in itself. It is an active pixel. Therefore, not only the speed can be greatly improved, but also the contrast and brightness can be greatly improved. At the same time, the resolution has reached a very high level.

The technical specifications of liquid crystal display module (TFT) provided by Xinhongtai Company are as follows:

Process types: monochrome TFT, color TFT (TN, VA, IPS);

Size specification: 1.14 inches to 12.3 inches;

Resolution: 128x128-1920x1200;

Interface types: 8-bit or 16-bit MCU parallel port,SPI, 24-bit RGB, LVDS, MIPI、VGA_HDMI、RS232_UART interface;

Provide matching: touch screen (resistance type, capacitance type), a variety of driving boards.


BL (BackLight)

Backlight is a kind of light source located behind liquid crystal display (LCD). Its luminous effect will directly affect the visual effect of liquid crystal display module (LCM). LCD does not emit light itself. It displays graphics or characters as a result of its light modulation.

The technical specifications of backlight (BL) provided by Xinhongtai Company are as follows:

Light source type: mainstream LED and EL, CCFL which almost stopped production;

Light source color: white, blue, green, yellow-green, amber and RGB;

Structure type: bottom light, flat side light, bracket side light (patch lamp, binding lamp, socket lamp)
