Pantalla matricial luminosa.Matrix luminous screen.
La presente solicitud tiene por objeto una pantalla matricial luminosa para formar gráficos en color y caracteres alfanuméricos, que está incluida en un panel de mensaje, y está formada por teselas de LED para la representación de pictogramas con resolución de 48x48 píxeles o mayor, así como caracteres alfanuméricos con resolución 21x15 por carácter o mayor, que aporta importantes ventajas e innovaciones frente a los distintos tipos de pantallas utilizadas en la actualidad con igual o similar fin.The purpose of this application is to luminous matrix display to form color graphics and alphanumeric characters, which is included in a message panel, and consists of LED tiles for the representation of pictograms with a resolution of 48x48 pixels or greater, as well as alphanumeric characters with 21x15 resolution per character or greater, which brings important advantages and innovations compared to different types of screens currently used with the same or similar end.
En la actualidad y como referencia al estado de la técnica, debe mencionarse en primer lugar que los paneles de mensaje variable existentes en la actualidad están basados principalmente en diseños que permiten resoluciones para la zona gráfica de 32x32 píxeles y de 7x5 en la zona alfanumérica. En la zona de representación gráfica hasta la fecha no se emplean LED de color blanco y por tanto se consiguen ratios de contraste y luminosidad inferiores. El control de la iluminación de un píxel se efectúa por filas y columnas encendiéndose o apagándose todos ellos a la vez, con lo cual la definición de ciertos caracteres alfanuméricos es baja.Currently and as a reference to the state of technique, it should be mentioned first that the panels of currently existing variable message are based mainly in designs that allow resolutions for the area 32x32 pixel and 7x5 graphic in the alphanumeric zone. In the graphic display area to date no LEDs are used white color and therefore you get contrast ratios and lower brightness. The control of the lighting of a pixel it is done by rows and columns turning on or off all them at the same time, thereby defining certain characters Alphanumeric is low.

Cada pantalla matricial está compuesta a partir de la combinación de teselas que incorporan píxeles que permiten la representación:Each matrix screen is composed from of the combination of tiles that incorporate pixels that allow the representation:
a) gráfica en aquellas zonas del panel en la que se desee mostrar elementos gráficos, por ejemplo pictogramas.a) graph in those areas of the panel in which you want to show graphic elements, for example pictograms.
b) alfanumérica en las zonas del panel en las que se desee mostrar también caracteres alfanuméricos.b) alphanumeric in the areas of the panel in the that you want to also display alphanumeric characters.
Cada tesela se divide a su vez en píxeles. Los
píxeles son agrupaciones de diodos de varios colores, que
constituyen un punto de luz. La novedad de las teselas que
conforman la pantalla de la presente invención radica en las
bondades que se obtienen a partir
de:Each tile is divided in turn into pixels. Pixels are groups of diodes of various colors, which constitute a point of light. The novelty of the tiles that make up the screen of the present invention lies in the benefits obtained from
from:
1.- La distribución de las teselas en píxeles, tanto en la zona gráfica como en la zona alfanumérica y la morfología de los píxeles, tanto en la zona gráfica como en la zona alfanumérica, debe entenderse tanto el tipo y número de LED que los componen, como la forma en la que éstos están agrupados. Así, cada tesela matricial presenta una zona en la que cada píxel permite la representación gráfica y alfanumérica, para lo cual está formado por cuatro LED de colores dispuestos en los vértices de un rombo, escoltados por cuatro LED de color ámbar, dispuesto en los vértices de un cuadrado circunscrito en el anterior; y opcionalmente otras zonas en las que cada píxel permite la representación gráfica, a efecto de lo cual está constituido por cuatro LED de colores dispuestos en los vértices de un rombo.1.- The distribution of the tiles in pixels, both in the graphic area and in the alphanumeric zone and the pixel morphology, both in the graphic area and in the area Alphanumeric, you must understand both the type and number of LEDs that they compose them, like the way in which they are grouped. So, each matrix tile has an area in which each pixel it allows the graphical and alphanumeric representation, for which it is formed by four colored LEDs arranged at the vertices of a rhombus, escorted by four amber LEDs, arranged in the vertices of a square circumscribed in the previous one; Y optionally other areas where each pixel allows the graphic representation, for which purpose it is constituted by four colored LEDs arranged at the vertices of a rhombus.
2.- La electrónica de control desarrollada para controlar la tensión a los LED para la emisión de luz, permiten en este caso controlar la tensión de forma individual a cada LED dentro de cada píxel. Con ello y con la disposición en cada punto alfanumérico de cuatro LED de color ámbar, se logra suavizar las fuentes de los, caracteres alfanuméricos al permitir, por ejemplo, encender únicamente tres y dejar el del vértice exterior de un carácter determinado apagado se consigue perfilarlo con mayor suavidad y definición.2.- The control electronics developed for Control the voltage to the LEDs for light emission, allow in this case control the voltage individually to each LED within each pixel With this and with the provision at each point alphanumeric of four amber LEDs, it is possible to soften the sources of the alphanumeric characters by allowing, for example, turn on only three and leave the outside vertex of a character determined off you can profile it with greater softness and definition.
3.- La incorporación de diodos blancos en cada píxel, de forma que no este color no se obtiene por encendido de los otros tres LED con los colores básicos (verde, azul y rojo), sino con el encendido únicamente de este de color blanco. Con ello se evita el brillo mayor en los puntos blancos y, como quiera que con el tiempo los colores no se degradan por igual, se evita que el color blanco vaya transformándose con el tiempo en rojizo como es habitual en otras pantallas convencionales con únicamente tres diodos de color por pixel, puesto que el verde se degrada más rápidamente que el rojo.3.- The incorporation of white diodes in each pixel, so that this color is not obtained by turning on the other three LEDs with the basic colors (green, blue and red), but with the ignition only of this white. With that the higher brightness in white dots is avoided and, however over time the colors do not degrade equally, it prevents the white color eventually becomes reddish as it is usual in other conventional screens with only three color diodes per pixel, since green degrades more Quickly than red.
4.- La separación entre dos píxeles consecutivos, tanto en una misma fila como en la misma columna, coincide con la distancia existente entre los LED de color ámbar que conforman cada píxel alfanumérico dispuesto en los vértices de un cuadrado, de forma tal que la representación de es más nítida y cuando se trata de un trazo lineal se aprecia una mayor continuidad.4.- The separation between two pixels consecutive, both in the same row and in the same column, matches the distance between amber LEDs that make up each alphanumeric pixel arranged at the vertices of a square, so that the representation of is sharper and when it comes to a linear stroke you can see a greater continuity.
Para complementar la descripción que se está realizando y con objeto de facilitar la comprensión de las características de la invención, se acompaña a la presente memoria descriptiva un juego de dibujos en los que, con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:
La figura 1 muestra una tesela en la que se puede apreciar la distribución en píxeles.Figure 1 shows a tile in which You can appreciate the distribution in pixels.
Las figuras 2 y 3 muestra respectivamente la morfología de los píxeles de la zona gráfica-alfanumérica y gráfica.Figures 2 and 3 show respectively the pixel morphology of the area graphic-alphanumeric and graphic.
Como se puede observar en las figuras referenciadas la pantalla matricial luminosa, formadora de imágenes en color, que está compuesta a partir de la combinación de varias teselas adosadas convenientemente en filas y columnas, cada una de las cuales está formada por una pluralidad de píxeles dispuesto así mismo en filas y columnas, que pueden ser de dos tipos:As can be seen in the figures referenced the luminous matrix screen, image maker in color, which is composed from the combination of several tiles attached conveniently in rows and columns, each of which is formed by a plurality of pixels arranged like this same in rows and columns, which can be of two types:
a) Píxeles para representación de gráficos únicamente, que se emplean en la zona del panel en la que se desee mostrar elementos gráficos; ya) Pixels for graphic representation only, which are used in the area of the panel where you want show graphic elements; Y
b) Píxeles que permiten la representación de caracteres gráficos y alfanuméricos, que se emplean en la zona del panel en la que se desee mostrar caracteres alfanuméricos.b) Pixels that allow the representation of graphic and alphanumeric characters, which are used in the area of panel in which you want to display alphanumeric characters.
Cada pixel está formado por agrupaciones de diodos emisores de luz LED de varios colores, controlados por un microprocesador.Each pixel consists of clusters of multi-colored LED light emitting diodes, controlled by a microprocessor.
En la zona gráfica y alfanumérica cada pixel (3) está formado por cuatro LED de colores dispuestos en los vértices de un rombo, escoltados por cuatro LED de color ámbar (C), dispuesto en los vértices de un cuadrado circunscrito en el anterior (ver figura 2).In the graphic and alphanumeric zone each pixel (3) It consists of four colored LEDs arranged at the vertices of a rhombus, escorted by four amber LEDs (C), arranged in the vertices of a square circumscribed in the previous (see figure 2).
En la zona únicamente gráfica cada pixel (2) está formado por cuatro LED de colores dispuestos en los vértices de un rombo (ver figura 3).In the only graphic area each pixel (2) It consists of four colored LEDs arranged at the vertices of a rhombus (see figure 3).
Los cuatro LED que permiten la representación gráfica, en ambas zonas de la tesela, se montan en los vértices de un rombo y son de color verde (G), azul (B), rojo (R) y blanco (W), encendiéndose en cada caso uno o varios LED para conseguir la tonalidad y el color deseados.The four LEDs that allow representation graphic, in both areas of the tile, are mounted on the vertices of a rhombus and are green (G), blue (B), red (R) and white (W), lighting in each case one or several LEDs to get the desired hue and color.
Como se puede apreciar en la figura 1 el lado del cuadrado que forman los cuatro LED de color ámbar (C) que concurren en cada pixel (3) que permite la representación alfanumérica coincide con la separación entre dos píxeles (3) consecutivos en la misma fila o columna, de forma que existe una continuidad lineal en cualquier dirección sin que se puedan distinguir puntos concretos en el trazo que forma un carácter u otro símbolo alfanumérico.As can be seen in figure 1 the side of the square formed by the four amber LEDs (C) that concur in each pixel (3) that allows the representation Alphanumeric matches the separation between two pixels (3) consecutive in the same row or column, so there is a linear continuity in any direction without being able to distinguish specific points in the stroke that forms a character or Another alphanumeric symbol.
Se ha previsto que el control de los LED que concurren en cada pixel se efectúe de forma individual lo que permite, no sólo una correcta formación de color en la zona gráfica, sino también una mejor definición de los caracteres alfanuméricos, puesto que en cada pixel pueden encenderse únicamente los LED necesarios para perfilarlo perfectamente al dividir cada punto o píxel en otros cuatro y éstos as su vez estar situados a igual distancia entre sí y con respecto al pixel anexo en cada fila o columna, particularmente cuando se trata de representar fuentes particulares o caracteres que no sean del alfabeto latino o con números arábicos.It is planned that the control of the LEDs that concur in each pixel is done individually what allows, not only a correct formation of color in the area graphic, but also a better definition of the characters alphanumeric, since in each pixel they can be lit only the LEDs needed to perfectly profile it at divide each point or pixel into another four and these as well be located at equal distances from each other and with respect to the annexed pixel in each row or column, particularly when it comes to representing particular fonts or characters other than the Latin alphabet or With Arabic numbers.
Una vez descrita suficientemente la naturaleza de la invención, así como un ejemplo de realización preferente, se hace constar a los efectos oportunos que los materiales, forma, tamaño y disposición de los elementos descritos podrán ser modificados, siempre y cuando ello no suponga una alteración de las características esenciales de la invención que se reivindican a continuación.Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not involve an alteration of the essential features of the invention claimed in continuation.
