Description

LCD display information board

technical field

The utility model relates to an information board, in particular to a liquid crystal display information board formed by assembling a liquid crystal panel.

Background technique

Light-emitting diodes (LEDs) have the unique features of high brightness, high reliability, and unlimited size. The most eye-catching application products are giant luminous and dynamically displayed signage. Among the many application fields of LED, LED electronic subtitle machine is one of the most important application fields, and it is mostly used in indoor single-machine and multi-machine connection operation; while large-scale LED billboards are used for outdoor large-scale advertisements, and LED system billboards are used in medical institutions, Factory production lines, air stations, railway and road arrival information, etc., especially the development of intelligent transportation systems, the instant release of information has become an important service content, so LED display equipment has become an important service for airports, railway stations, docks, bus stations, expressways, Traffic places such as urban roads and parking lots are the best protagonists to convey instant information to the public.

The LED display system operates roughly in two ways. One is to pre-edit the content to be displayed on the input device installed with the system program, and then transmit the data to the display module for display through a wired or wireless communication interface; the other It is combined with the management and control center system. Through the operation of the system, the data can be transmitted and received through the wired or wireless communication interface, so that the display module can play in real time. It is usually used in traffic timetables or factory production lines.

However, using LED as the smallest display unit (pixel) has the following disadvantages. For example, the resolution of the LED electronic subtitle machine is poor. The resolution becomes worse, which greatly affects the viewing quality. In order to improve the resolution, a small package LED is usually used as a single light-emitting element, but this relatively causes problems such as an increase in the unit price of the product, an increase in power consumption, and an increase in material consumption.

In addition, due to the light-emitting characteristics of LED itself and cost considerations, most LED system signages are monochrome models, while LED monochrome models can only display red characters/black background, green characters/black background, orange characters/black background, and the color The performance is a bit monotonous; if a color model is used, there are still problems of poor resolution and high price.

And after a long time of use, the brightness of each LED is often attenuated differently, making the display screen bright and uneven. During the dynamic display, the display screen will also be due to the above-mentioned characteristics of LEDs, and the viewer will feel that the luminous patterns and fonts have a wave or floating feeling due to the relationship of visual persistence.

Utility model content

Therefore, the main purpose of this utility model is to achieve the effect of displaying information through the liquid crystal display module, and improve the defects of known LED electronic subtitle machines that are too bright, dazzling, poor resolution, and relatively inflexible in resolution design.

Problems such as waves and floating screen deformation.

Another purpose of the present invention is that the modularization of the liquid crystal display unit of the present invention can be combined into various types of liquid crystal display boards, and the size of the liquid crystal display boards required by users can be combined at low cost and in a variety of ways.

The utility model relates to a liquid crystal display information board, which comprises a control device installed with information board operation software for editing a series of displayed information content and the display mode of the information content in multiple columns; a transmission device converts the edited The information is transmitted in standard communication protocol interface format; at least one liquid crystal display board is used to display the information edited by the control device; and at least one display control device is used to receive and store the data transmitted by the transmission device, and control the liquid crystal display Kanban display action.

Each liquid crystal display board is composed of at least one liquid crystal panel and a display control device. Therefore, the advantages of the utility model are that a plurality of liquid crystal panels can be connected in series to form a required liquid crystal display board. And the number of the liquid crystal display boards in use of the present invention can be single or multiple liquid crystal display boards forming a group to accept the control of a single display control device, or a single display control device to control multiple groups of liquid crystal display Kanban, thereby expanding the range of the liquid crystal display information Kanban, which can be transmitted and displayed.
