OK204-25-OR-VPT Application Field and Working Principle

The OK204-25-OR-VPT display module is a character and numeric display module that belongs to the LCD, OLED character and numeric category of display modules. Developed by OKAYA Electric Co., Ltd., the module has a wide range of application fields. It is used in appliances such as radios, televisions, refrigerators, microwaves and other home appliances, as well as in industrial automation and instrumentation, medical devices, and automotive electronics.

In general, the OK204-25-OR-VPT display module features a dot matrix configuration of 5x7. It has a 4 digit readout display with a 20mm height of the characters in the display area. The module has a built-in liquid crystal controller, which takes out the complexity involved in building the display module from scratch. The Liquid Crystal Display (LCD) technologies used in the module is passive matrix addressing technology. It also features a wide operating temperature range of -40OO C to + 75OO C and excellent light stability.

In terms of power requirement, the module operates on wide voltage range of 5VDC to 18VDC and its nominal supply voltage is 12VDC with 15mA current drain. The module has a black character display with a wide operating temperature range of -20OO C to + 70OO C. The contrast of the display can be adjusted with the use of the contrast adjustability.

The OK204-25-OR-VPT module is a reliable display with a high contrast and good readability. The excellent resolution of the display ensures that it can be used in devices with limited space. The display also has a low power consumption and can work with low power supply.

The working principle of the OK204-25-OR-VPT display module involves the use of thin film transistor switching method. This is based on the use of an electrical current to produce a voltage difference between the two sides of the liquid crystal. The voltage difference is responsible for changing the polarization of the light passing through the liquid crystal and thus, changing the light intensity of the display. The voltage difference is produced in the plane between the two sides of the liquid crystal. When there is no voltage, the liquid crystal molecules pass light without any distortion and the display appears clear. When there is a voltage, the molecules undergo an orientation change, distorting the light and causing the display to appear differently.

In the OK204-25-OR-VPT display module, each pixel has its own address, which is used to control the voltage differences between the two sides of the liquid crystal and thus, control the light intensity of the display. In addition to controlling the intensity, the module also provides the functionality of controlling the contrast of the display. The contrast of the display can be controlled by controlling the voltage differences between the two sides of the liquid crystal.

In conclusion, the OK204-25-OR-VPT display module is a reliable character and numeric display module that belongs to the LCD, OLED character and numeric category of display modules. It has a wide range of application fields and features a dot matrix configuration of 5x7. The module also has a built-in liquid crystal controller, a wide operating temperature range and excellent light stability. The working principle of the module is based on the use of an electrical current to produce a voltage difference between the two sides of the liquid crystal, which is responsible for changing the polarization of the light passing through the liquid crystal, thus changing the light intensity of the display.
