DETAILED DESCRIPTION

[0021] Detailed description of the present invention will be further described below with reference to the accompanying drawings. It should be stated that the purpose of illustration of these implementations is to facilitate understanding the present invention and not to limit the invention. Additionally, involved technical features in each implementations of present invention described below can be combined as long as they do not conflict with each other.

[0022] As shown in FIGS. 1-3, a multi-layer display device for animation of the present disclosure comprises: a light guiding plate 1, a controller 2 and a light source 3, wherein a teletext 4 is provided on the light guiding plate 1, a display panel assembly 5 is formed by several light guiding plates 1 having different teletexts 4 in the form of lamination, the light source 3, which can be independently controlled, is provided on at least one side edge of each light guiding plate 1, light emitted from the light source 3 is irradiated into the light guiding plate 1 through the side edge, the light source 3 is electrically connected to the controller 2. An integral display panel assembly 5 is formed by several light guiding plates 1 having different teletexts in the form of lamination, and the teletext on the multi-layer light guiding plate 1 can be configured as a static frame teletext 4 which presents dynamic action from inside to outside or from outside to inside. Individual light source 3 provided on side edge of each light guiding plate 1 irradiate onto the corresponding light guiding plate, as the teletext with rough surface 4, like uneven spot, is provided on light guiding plate 1. When light transmit past the spot position of the teletext, straight-line path of light is interfered to create reflex phenomenon such as refraction, diffuse reflection and etc. In the view of visual effect, it seems that the teletext is illuminated and presented to users. The teletext 4 can be concave spot, and also can be convex spot. Light source 3 irradiates the teletext 4 to refract light, or reflect light into eyes in operation. For example, teletexts on each light guiding plates are designed as a series of images constituting dynamic actions such as continuous burning fire, running person and etc. When every individual light source irradiates the teletext on light guiding plates, the teletext could only display illuminated teletext portion immediately. Controller 2 controls switch on-off of each individual light source. Several light sources 3 are sequentially turned on and off according to the signal of the controller 2 to irradiate the corresponding light guiding plates 1 respectively. Each layer of the multi-layer light guiding plate 1 is sequentially illuminated so as to present different pictures to form a continuous dynamic display teletext. The overall structure is simple, and the display effect is good. Additionally, individual light source could be configured as multi-line light sources on a piece of substrate corresponding to light guiding plates 1. Controller 2 is electrically connected to each line of light source and controls switch on-off of each line of light source.

[0023] As embodiment 1 shown in FIG. 1, the light guiding plates 1 of the embodiment is a transparent acrylic plate on which surface the teletext 4 is formed by laser spotting. Such as teletext on several light guiding plates 1 can be designed as static frames of a series of coherent motions of flying phoenix. Each individual light source 3 sequentially irradiated corresponding light guiding plates 1, and each frame of multi-layer light guiding plates 1 sequentially illuminated to form a coherent dynamic motion of flying phoenix. The method of the embodiment has a realistic effect. It can also employ transparent material, such as glass plate, resin plate, plastic plate, crystal or film when implementing this embodiment.

Additionally, the light guiding plates 1 can be designed as fan-shape, trapezoidal, square or flat graphics according to actual requirement of display so as to increase usage scenario. Single chip microcontroller is employed as the controller 2 of light guiding plates 1. The teletexts on the light guiding plates 1 of the embodiment are static frames of a series of actions of burning fire. Each individual light source 3 is sequentially or disorderly on/off by the controller 2 respectively. Separate fire patterns on multi-layer light guiding plates 1 is illuminated. Different light guiding plates 1 disorderly illuminated can form a dynamic burning fire in different forms through permutations and combinations. The illuminated fire has a realistic effect. Identical light sources 3 are provided at both sides of light guiding plates 1. The two light sources 3 are connected to a signal output port of the same single chip microcontroller. Light sources 3 receive signals of the same frequency-occupation ratio to turn on or off light sources 3 at the same time. It can increase the luminance of the illuminated teletext to make the teletext on the light guiding plates 1 more clear.

[0025] Additionally, it can employ an LED lamp bead or LED module as the light source 3. The LED module is electrically connected to drive power. PWM drive circuit is further electrically connected between the single chip microcontroller 2 and the light source 3. The single chip microcontroller outputs regulate signal to control that the PWM drive circuit outputs signal which in turn controls the light source 3 to sequentially or disorderly turn on or off. PWM outputs signal is stable that can make the pattern illuminated on the light guiding plates 1 coherent and smooth. There is a gap between the adjacent two light guiding plates 1, and a distance therebetween is not more than 1 mm in order to reduce the impact of adjacent light sources 3 to the light guiding plate 1 and reduce undesired effect of residual images. A shutter is provided between the light sources 3 corresponding to adjacent two light guiding plates 1. It can prevent light leakage of light source 3 to be projected to adjacent light guiding plates 1 to bring out residual images. A light-insulation layer is provided on outer surface of lower section between adjacent two light guiding plates 1. The light-insulation layer can be a coating at lower section of one of the two light guiding plates, or also can be a material provided at lower section of the adjacent two light guiding plates, such as light-insulation film and etc. The light-insulation layer is provided at lower section of the light guiding plates, adjacent to the root portion, and can prevent light from interfering each other between adjacent two light guiding plates.
