Description
Technical field
The present invention relates to a kind of liquid-crystal display information board, the formed information board of particularly a kind of display panels system.
Background technology
Light emitting diode (LED) has the unrestricted unique function of high brightness, high-reliability and size, and the most eye-catching application product is exactly huge brilliance and the dynamic billboard that shows.In addition, in numerous applications of LED, LED electronics film titler is one of most important applications field wherein, and it is more common in indoor unit, multimachine on line operation; And the large LED billboard is used for the outdoor large advertisement, LED system billboard is used for medical institutes, plant produced line, airport, the iron highway information etc. of arriving at a station, the particularly development of intelligent traffic system, the real-time release of information becomes important service content, so the LED display device becomes real-time information is passed in traffic places such as airport, railway station, harbour, bus stop, highway, urban road, parking lot for the public best leading role.
This LED display system function mode roughly has two kinds, one for be equipped with edit in advance on the input equipment of system program desire content displayed after, data are reached the display module displays with wired or wireless communication interface; Another then is to combine with the management and control centring system, by the running of system, can so that the display module is done real-time play, be generally used for transit schedules or factory and produce on the living pipe of line with data with wired or wireless communication interface transmission and reception data.
But as showing minimum unit (pixel), have following shortcoming, the resolution rate variance of LED electronics film titler with light emitting diode (LED), when closely watching, can obviously see many LED light-emitting component, make the resolution variation of literal or picture, quality is watched in influence.In order to improve resolution, can change into usually and adopt little encapsulated LED, but cause problems such as production unit cost raising, power consumption, material consumption increase relatively as single light-emitting component.
In addition, because the characteristics of luminescence of LED itself and cost, LED system billboard mostly is monochromatic machine, and the monochromatic machine of LED only can present The Scarlet Letter/black matrix, green word/black matrix, orange word/black matrix, dislikes dull in the performance of color slightly; If adopt colored machine, then still have and differentiate rate variance and problem of ultra-high price.
And after long-time the use, regular meeting is because the attenuation amplitude difference of every LEDs brightness makes display frame bright uneven.When dynamically showing, display frame also can be because of the above-mentioned characteristic of LED, and the beholder can be because the relation of persistence of vision thinks that luminous pattern and font have wave or floating sensation.
Summary of the invention
Fundamental purpose of the present invention is, reaches the effect of display message by the liquid crystal display module, and traditional LED electronics film titler is too bright, dazzling, resolution is relatively poor, resolution designs inelastic defective thereby improve.
Of the present invention time a purpose is, the present invention can effectively reduce the power consumption of existing LED electronics film titler, color dullness, with because each LEDs brightness decay amplitude is different, cause the display frame brightness disproportionation, display frame has problems such as wave, floating picture distortion when dynamically showing.
Another object of the present invention is to, liquid crystal display modularity of the present invention, the liquid crystal display billboard of the various attitude of one-tenth capable of being combined can the low-cost and required liquid crystal display billboard of the diversified ground person of being used in combination.
The present invention is a kind of liquid-crystal display information board, and it comprises: a master control system is equipped with the information board function software, in order to edit a succession of, the information content of multiple row to display and the display mode of the information content.One transport interface sends out the information behind the editor with standard communications protocol interface formats.
The information of at least one liquid crystal display billboard in order to show that this master control system is edited.Reach at least one control system reception and store the data that this transport interface spreads out of, and control the display action of this liquid crystal display billboard.Wherein each liquid crystal display billboard is made up of at least one display panels and drive circuit board, a plurality of display panels serial connections can be formed the sample attitude of required liquid crystal display billboard by tandem link.And the number of this liquid crystal display billboard in the use, can be that single or a plurality of liquid crystal display billboard form the common control of accepting single control system of a group, or control the liquid crystal display billboard of multigroup group respectively by single control system, enlarge this liquid-crystal display information board by this and can transmit and the regional extent that shows.
