China 3.0 inch lcd display 240*400 MCU ST7793 Manufacturers, Suppliers, Factory

Usually, touchable LCD screens are capacitive screens, and the positioning method of the touch screen is through the electric field. Therefore, when static electricity and discharge occur, the LCD touch screen will have a "drift" screen effect, that is, the click position is offset from the actual response position.

In addition, when designing the touch screen circuit principle, the grounding of the FPC cable can be increased, or the touch screen cable can be covered with double-sided black electromagnetic film, which can also reduce the electromagnetic interference problem of the touch screen in practical applications. Shenzhen Hongjia Technology has been professionally developing and producing 1.14-inch to 10.1-inch displays and supporting touch screens for 12 years. It has a R&D team of more than 20 people who are familiar with solving common problems in the industry and can reduce troubles for customers.

Backlighting is used in small, light, flat-panel liquid crystal displays (LCDs) and other electronic devices that require backlighting, including handheld devices as small as the palm of your hand, and large-screen TVs. The goals of backlight design include low power consumption, ultra-thin, high brightness, uniform brightness, large area, and control of different width and narrow viewing angles. To achieve these challenging design goals with controlled cost and rapid implementation, computer-aided optical design tools must be used for design. This article introduces the characteristics of LightTools optical design and analysis software from ORA Company in the United States, which can be used to develop the most advanced backlight design applications today.

Our company has developed a 4.3-inch vertical screen and has been mass-produced. The display supports MCU interface 8BIT and 16BIT. The screen driver IC has video memory, which can realize the flip display of the screen.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

The 2.0-inch 1U chassis TFT screen produced by Shenzhen Hongjia Technology Co., Ltd. has an outer size of 34.76mm*47.86mm, which can be perfectly installed in a 1U chassis. It has a resolution of 240*320, 4 high-brightness lights, IPS full viewing angle, supports SPI and MCU interfaces, and can be displayed horizontally. Customers are welcome to email for consultation.
