Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of display panel 10, and as shown in Figure 2, this display panel comprises viewing area 10a and non-display area 10b; Described display panel further comprises: be arranged at least one luminescence chip 40 of described non-display area 10b and control the luminous control circuit 30 of described at least one luminescence chip.
It should be noted that, the first, in the embodiment of the present invention not the quantity to luminescence chip 40 limited.
The second, controlling the luminous control circuit 30 of described luminescence chip 40 can be to control the simultaneously luminous circuit of a plurality of luminescence chips 40 simultaneously, can be also to control its luminous circuit for any luminescence chip 40.
, consider in actual use, whether luminously wish to control neatly luminescence chip 40, the embodiment of the present invention, be preferably, and for any luminescence chip 40, has one for controlling the luminous control circuit 30 of this luminescence chip 40 herein.
The 3rd, for the setting position of described luminescence chip 40 and described control circuit 30, the non-display area 10b that can be arranged at least one side in the left and right sides of display panel 10 place that keeps to the side.
The 4th, for realizing the display panel 10 shown by external light source, prerequisite is that the light that external light source sends needs to arrive display panel 10, therefore, in this bright embodiment, when display panel 10 is applied to display, also should comprise can will be arranged on the light that sends of the luminescence chip 40 on display panel import the parts of display panel 10, do not do detailed description at this.
Embodiments of the invention provide a kind of display panel, and described display panel comprises viewing area and non-display area, also comprise at least one luminescence chip that is arranged on described non-display area and control the luminous control circuit of described at least one luminescence chip; With respect to the display panel that need to be shown by the light source provided in backlight source module in prior art, the embodiment of the present invention is by being arranged on luminescence chip and control circuit on display panel, make this display panel can automatic light source and help external light source without relending, thereby described display panel is shown by the light source of self, and when described display panel is used for display, can reduce the overall volume of backlight source module, be conducive to the lightening development of display.
Optionally, when described display panel 10 is display panels 100, as shown in Figure 3, described display panels 100 comprises array base palte 101, color membrane substrates 102 and is arranged on the liquid crystal layer 103 between described array base palte 101 and described color membrane substrates 102; Wherein, described luminescence chip 40 and control the luminous control circuit of described luminescence chip 30 and all be arranged on described array base palte 101, and described luminescence chip 40 is arranged on described array base palte near described color membrane substrates 102 1 sides.
Certainly, when this display panels 100 is applied to liquid crystal display, described liquid crystal display can also comprise and is arranged on array base palte 101 away from the light guide plate 202 of color membrane substrates 102 1 sides, blooming piece 203 etc., so that the luminous energy that luminescence chip 40 sends imports the viewing area 10a of described display panels 100.
Here, on the one hand, as shown in Figure 4, consider in the preparation process of described display panels 100, owing to needing to arrange the device that drives the transistor work in described array base palte on array base palte 101, the area of the array base palte 101 in the display panels 100 therefore formed afterwards in cutting is greater than the area of color membrane substrates 102, so in the embodiment of the present invention, when described luminescence chip 40 is arranged on at least one side of described array base palte 101 close described color membrane substrates 102, can avoid making the thickness of described display panels 100 to increase.
On the other hand, because light source in prior art 201 is arranged at least one side of the left and right sides of backlight source module 200, its light sent need to could arrive light guide plate 202 through the space of certain-length, can cause like this inciding the interior light intensity of light guide plate 202 inhomogeneous, after the light through light guide plate 202 outgoing is injected display panels 100, can cause this display panels 100 brightness disproportionation phenomenon (Hot Spot) to occur, and in the embodiment of the present invention, when described display panels 100 is applied to liquid crystal display, import the viewing area 10a of this display panels 100 for making to be arranged on light that the luminescence chip 40 on described display panels 100 sends, need to arrange light guide plate 202, and described light guide plate 202 can arrange near array base palte 101, like this, the gap of the light arrival light guide plate 202 that luminescence chip 40 sends is smaller, can improve to a certain extent the inhomogeneous phenomenon of light intensity incided in light guide plate 202, and then improve display panels 100 and the brightness disproportionation phenomenon occurs.
Again on the one hand, because liquid crystal display described in prior art also comprises PCB, described PCB comprises for controlling the luminous circuit of light source 201, so just make the light source 201 that is arranged in backlight source module 200 at least one side places, the left and right sides need be connected with the circuit on PCB by lead-in wire, can cause like this power consumption of light source 201 can be larger; And in the embodiment of the present invention, described control circuit 30 can be formed in array base palte 101 by composition technique, because the resistivity of control circuit 30 cabling wherein formed by composition technique is smaller, make the power consumption of the luminescence chip 40 be connected with control circuit 30 smaller.
Preferably, for any luminescence chip 40, described control circuit 30 comprises for controlling the luminous sub-control circuit of described any luminescence chip 40.
Like this, by described sub-control circuit, whether luminously can control flexibly any luminescence chip 40.
Further, as described in Figure 5, described sub-control circuit comprises the first switch element 301, second switch unit 302 and the 3rd switch element 303; Wherein, the drain electrode 301c of described the first switch element is connected with described luminescence chip 40, the source electrode 301b of described the first switch element is connected with drive IC 80 by described the 3rd switch element 303 by the grid 301a of described second switch unit 302, described the first switch element, and drive IC 80 is for providing voltage to respectively described source electrode 301b and described grid 301a.
It should be noted that, due to described drive IC 80 outputs is digital signal, need to the described digital signal of drive IC 80 outputs be converted to voltage signal by second switch unit 302, thereby voltage be provided to the described source electrode 301b be connected with described second switch unit 302; Same, described drive IC 80 need to be converted to voltage signal by the described digital signal of drive IC 80 outputs by the 3rd switch element 303, thereby voltage is provided to the described grid 301a be connected with described the 3rd switch element 303.
Based on foregoing description, preferred, described luminescence chip 40 can be LED (Light Emitting Diode, light emitting diode) chip 400.
Herein, due to described LED chip 400 only has a face can be luminous, therefore, when this LED chip 400 is arranged on display panel 10, the setting position of its light-emitting area is finally injected described display panel 10 with the light that can make described LED chip 400 send and is as the criterion.
