Just above-mentioned electroluminescence display panel provided in an embodiment of the present invention is entered with the structure shown in Fig. 4 to Fig. 6 below
Row describes in detail.
In the specific implementation, by taking mobile phone as an example, in mobile phone not enough power supply, in order to reduce the use of electricity, extend and use
Time, display resolution can be shown that being reduced to low resolution shows from normal high-resolution；In addition, only carried out in mobile phone
During text importing, because the resolution ratio that the display of word need not be higher is that can be achieved to clearly show that, it is possible to carry out low point
Resolution shows word；Certainly, in holding state, or only need to show the time or during simple image, low resolution can also be carried out
Display.
Specifically, in order in low resolution display image, reducing the power consumption of system, can be shown according to electroluminescent
Show the resolution ratio of the image of Display panel, special setting is carried out to the working condition of each pixel cell 11；Such as：In electroluminescent hair
It is, it is necessary to which the working condition for ensureing each pixel cell 11 is dispaly state during light display panel display of high resolution images, i.e., every
Pixel control circuit in individual pixel cell 11 is in working condition；And show low resolution figure in electroluminescence display panel
During picture, then and the working condition of each pixel cell 11 need not be made to be dispaly state, can be according to from high-resolution to low
The reduction multiple of resolution ratio, the working condition of each pixel cell 11 is adjusted and controlled, so as to need the picture of display image
The working condition of plain unit 11 is dispaly state, and the working condition without the pixel cell 11 of display image is non-display shape
State, effectively to reduce the power consumption of system, extend the usage time of display device.
Specifically, in order to realize that low resolution is shown, the power consumption of system is reduced, on provided in an embodiment of the present invention
State in electroluminescence display panel, each group control circuit, specifically in normal display resolution display picture, being controlled corresponding
Under the control for the control signal that line 22 processed inputs, luminous signal, the corresponding each pixel list of control are inputted to corresponding luminous signal line 12
The working condition of member 11 is dispaly state；When display resolution reduces, in the control for the control signal that corresponding control line 22 inputs
Under system, luminous signal is inputted to corresponding luminous signal line 12, control section pixel cell 11 shows the work in the time in a frame
State is non-display state；Therefore, either normal display image, or low resolution display image, by control circuit
Packet sets and can realized so that while ensureing that electroluminescence display panel is normally shown, can also realize low resolution
Rate is shown, so as to effectively reduce the power consumption of system.
It is preferred that in order to which when display resolution reduces, the working condition of control section pixel cell 11 is non-display shape
State, the working condition of control section pixel cell 11 is dispaly state, is shown in above-mentioned electroluminescent provided in an embodiment of the present invention
Show in panel, as shown in Figures 4 to 6, whole control circuits 21 are divided into two groups；One of which control circuit, for showing

Non-display state.Specifically, in order to avoid the complexity of accompanying drawing, two groups of control circuits are only given in Fig. 2 to Fig. 4 and Fig. 6
Mark；Wherein, Va1 and Va2 represents the packet of the control circuit progress to line direction respectively, and Vb1 and Vb2 represent to row side respectively
To control circuit be grouped.
Certainly, when being grouped to whole control circuits 21, each control circuit 21 can also be divided into one group, it is right
Ying Di, it is intended to set one group of control line 22 for each group of control circuit, i.e. how many group of control circuit 21, control line 22 just has more
Few group；However, although this kind of group technology goes for the reduction multiple of any display resolution, but due to one being controlled
Circuit 21 is divided into one group, thus needs to set more control line 22, so as to significantly take the area of frame, is unfavorable for
The design of narrow frame；Therefore, the present invention carries mainly so that whole control circuits 21 are divided into two groups as an example to the embodiment of the present invention
The above-mentioned electroluminescence display panel supplied is described in detail.
Specifically, two groups of generative circuits can be arranged at a side of viewing area 10, as shown in Figure 2 and Figure 4, i.e., single
Side drives；However, because signal wire is arranged longer, significantly pressure drop can be caused during unilateral driving, and signal delay is more tight
Weight；In order to solve this problem, two groups of generative circuits as shown in Figure 5 and Figure 6, can be respectively arranged to the phase of viewing area 10
To two sides, bilateral driving is realized, can not only reduce pressure drop, the phenomenon of signal delay can also be effectively improved；Therefore, exist
In above-mentioned electroluminescence display panel provided in an embodiment of the present invention, two groups of generative circuits are respectively arranged at the phase of viewing area 10
To two sides (as shown in Figure 5 and Figure 6)；Or, two groups of generative circuits may be contained within side (such as Fig. 2 for viewing area 10
Shown in Fig. 4).
Further, when whole control circuits 21 are divided into two groups, can be reduced according to display resolution specific
Multiple, control circuit 21 is grouped；For example, by taking the structure shown in Fig. 4 and Fig. 5 as an example, in order to avoid the complexity of accompanying drawing,
The mark of two groups of control circuits is only given in Fig. 2 to Fig. 4 and Fig. 6, display resolution reduces in line direction and column direction
It at twice, can be grouped according to odd even, i.e., the generative circuit 21a of odd-numbered line is divided into one group, as Va1, by even number
Capable generative circuit 21a is divided into one group, as Va2；Similarly, the multiplexer circuit 21b of odd column is divided into one group, i.e.,
For Vb1, the multiplexer circuit 21b of even column is divided into one group, as Vb2；And when display resolution is in line direction and row
When direction reduces three times, structure as shown in Figure 6, the generative circuit 21a of the first row and fourth line is divided into one group, is
Va1, the generative circuit 21a of remaining rows is divided into one group, as Va2；Similarly, multi-path choice electricity first row and the 4th arranged
Road 21b is divided into one group, as Vb1, the multiplexer circuit 21b of remaining columns is divided into one group, as Vb2.Usually, show
The reduction multiple of resolution ratio is identical with the reduction multiple on column direction in line direction；Certainly, can also basis except special requirement
Reduction multiple of the actual requirement on line direction and column direction, which is set, to be differed, and is not limited thereto.Therefore, retouched according to above-mentioned
State, no matter display resolution reduces how many times in line direction and column direction, in above-mentioned electroluminescent provided in an embodiment of the present invention
In display panel, two neighboring working condition is that to be at least spaced a working condition between the pixel cell 11 of dispaly state be non-
The pixel cell 11 of dispaly state.
It is pointed out that when display resolution reduces three times in line direction and column direction, point of control circuit 21
Group situation is as shown in Figure 6；However, generally, in order to ensure the working time of each pixel cell 11 balance, it is necessary to every
Just need to change position of the one action state for the pixel cell 11 of dispaly state every certain time；Therefore, if with shown in Fig. 6
Structure when being grouped to control circuit 21, it is difficult to ensure that the alternating of each pixel cell 11 is shown, so every in order to ensure
The working time balance of individual pixel cell 11, and reduce the power consumption of system and ensure the display effect of image, it is usually, adjacent
Two working conditions be dispaly state pixel cell 11 between interval one working condition be non-display state pixel cell
11。
It is preferred that display resolution is being reduced, and while reducing system power dissipation, in order to not influence the display effect of image,
Usually, it is the reduction multiple of display resolution is identical with the reduction multiple on column direction in line direction, and 2 times are reduced, because
This, in above-mentioned electroluminescence display panel provided in an embodiment of the present invention, as shown in Figure 4 and Figure 5, two neighboring working condition
The pixel cell 11 that a working condition is non-display state is spaced between the pixel cell 11 of dispaly state；Driving is strange
Each generative circuit 21a of several rows of each pixel cells 11 forms one group of generative circuit Va1；Drive each of each pixel cell 11 of even number line
Generative circuit 21a forms one group of generative circuit Va2.
Further, in order to reduce pressure drop and improve the phenomenon of signal delay, in above-mentioned electricity provided in an embodiment of the present invention
In photoluminescence display panel, as shown in figure 5, two groups of generative circuits are respectively arranged at relative two sides of viewing area 10, i.e.,
One group of generative circuit of driving each pixel cell 11 of odd-numbered line is arranged at the left side of viewing area 10, drives each pixel list of even number line
One group of generative circuit of member 11 is arranged at the right side of viewing area 10；It is, of course, also possible to each pixel cell 11 of even number line will be driven
One group of generative circuit be arranged at the left side of viewing area 10, one group of generative circuit for driving each pixel cell 11 of odd-numbered line is set
The right side of viewing area 10 is placed in, is not limited thereto.
It is preferred that the packet for multiplexer circuit 21b is set, in above-mentioned electroluminescent provided in an embodiment of the present invention
In display panel, as shown in Figure 4 and Figure 5, two neighboring working condition is spaced one between the pixel cell 11 of dispaly state
When working condition is the pixel cell of non-display state, each multiplexer circuit 21b structures of each pixel cell 11 of odd column are driven
Into one group of multiplexer circuit Vb1；Each multiplexer circuit 21b of each pixel cell 11 of even column is driven to form one group of multichannel choosing
Select circuit Vb2.
Further, because multiplexer circuit 21b is generally positioned at the output end of source electrode driver, and source electrode driver
A side of viewing area 10 is generally positioned at, therefore, in above-mentioned electroluminescence display panel provided in an embodiment of the present invention
In, as shown in Figure 4 and Figure 5, two groups of multiplexer circuits may be contained within a side of viewing area 10.
In the specific implementation, in electroluminescence display panel, pixel cell 11 includes pixel control circuit, and with picture
The luminescence unit of plain control circuit electrical connection, luminescence unit light under the control of pixel control circuit, so as to realize display
Function；And in comparative example, no matter whether display resolution reduces, the pixel control circuit in each pixel cell 11 is located
In working condition, i.e. thin film transistor (TFT) in pixel control circuit is work；Simply, when high-resolution is shown, pixel control
Circuit processed controls luminescence unit normal luminous, is shown in low resolution, and pixel control circuit reduces the luminosity of luminescence unit
Or control luminescence unit does not light；So so that when low resolution is shown, the pixel control circuit in pixel cell 11 is also
In running order so that the power consumption of system can not be reduced effectively；And provided in an embodiment of the present invention above-mentioned electroluminescent
In light emitting display panel, non-display state of the pixel cell 11 within the frame display time is the picture being arranged in pixel cell 11
Plain control circuit is in off working state, wherein it is possible to be that whole thin film transistor (TFT)s are in off working state, or it is most of thin
Film transistor is in off working state, as long as can ensure that pixel control circuit is in off working state, does not limit herein
It is fixed；Therefore, the control of generative circuit 21a and multiplexer circuit 21b in control circuit 21 are passed through so that without display image
Pixel cell 11 in pixel control circuit be in off working state, i.e. the not work of thin film transistor (TFT) in pixel control circuit
Make, correspondingly, corresponding luminescence unit would not also light so that corresponding pixel cell 11 not display image, so as to effectively
Ground reduces the power consumption of system, extends the service life of display device.
In the specific implementation, due to when display resolution reduces, at the pixel control circuit in partial pixel unit 11
In off working state so that the working condition of the partial pixel unit 11 is non-display state, i.e., the partial pixel unit 11 is not
Display image, and the then display image of rest of pixels unit 11；Therefore, in order to ensure that the working time of each pixel cell 11 puts down
Weighing apparatus, it can show that the time changes position of the one action state as the pixel cell 11 of dispaly state using a frame.
For example, by taking the structure shown in Fig. 7 a to Fig. 7 d as an example, wherein, show 16 pixel cells 11, and odd-numbered line
Generative circuit 21a is one group, and the generative circuit 21a of even number line is one group, and similarly, the multiplexer circuit 21b of odd column is one
Group, the multiplexer circuit 21b of even column is one group；Also, for convenience of description, distinguish label for each pixel cell 11,
It is followed successively by from left to right according to every row：11-1、11-2、11-3、11-4、11-5、11-6、11-7、11-8、11-9、11-10、11-
11st, 11-12,11-13,11-14,11-15 and 11-16；Also, when the luminescence unit in pixel cell 11 is that vertical line is filled
The working condition for representing the pixel cell 11 is dispaly state；When display resolution is reduced to 2*2 by 4*4, show in the first frame
Show in the time, as shown in Figure 7a, under generative circuit 21a and multiplexer circuit 21b control, working condition is dispaly state
Pixel cell 11 be respectively 11-2,11-4,11-10 and 11-12；Shown in the second frame in the time, as shown in Figure 7b, in order to protect
The working time for demonstrate,proving each pixel cell 11 is balanced, it is necessary to adjust the pixel cell 11 that working condition is dispaly state, i.e., herein
Frame shows in the time that working condition is that the pixel cell 11 of dispaly state is then：11-6,11-8,11-14 and 11-16；The 3rd
Frame was shown in the time, as shown in Figure 7 c, needed also exist for adjusting the pixel cell 11 that working condition is dispaly state, therefore, herein
Frame shows in the time that working condition is that the pixel cell 11 of dispaly state is：11-1,11-3,11-9 and 11-11；In the 4th frame
Show in the time, as shown in figure 7d, need also exist for adjusting the pixel cell 11 that working condition is dispaly state, i.e., shown in this frame
In time, working condition is that the pixel cell 11 of dispaly state is：11-5,11-7,11-13 and 11-15；Therefore, one is often shown
Two field picture, it is necessary to the position for the pixel cell 11 that one action state is dispaly state is adjusted, to be advantageous to each pixel list
The working time of member 11 is balanced.
As soon as if however, often showing two field picture, adjustment one action state is the position of the pixel cell 11 of dispaly state
Put, then, it is necessary to ceaselessly adjust during the display of image so that system power dissipation can not be reduced further；Therefore,
, can be in switching on and shutting down in order to further reduce system power dissipation, or be display shape to working condition when display screen is waken up
The position of the pixel cell 11 of state is adjusted, and by reducing the adjustment number of display location, further reduces the power consumption of system.
In the specific implementation, in order to realize by two groups of control circuits, the work of pixel cell 11 corresponding to control
State, in above-mentioned electroluminescence display panel provided in an embodiment of the present invention, the first control signal is with the second control signal
Control signal with different sequential.
Specifically, in the conventional configuration as shown in figure 5, control circuit 21 includes：The generative circuit 21a of LED control signal and
Multiplexer circuit 21b, control line 22 include：Thread switching control 22b and clock cable 22a, luminous signal line 12 include：Hair
Optical control signal line 12a and data signal line 12b；Wherein, due to generative circuit 21a is divided into two groups, therefore, clock signal
Line 22a also has two groups, is electrically connected respectively with every group of generative circuit, for controlling generative circuit 21a outputs are luminous control letter occurs
Number, i.e., first group of clock cable 22a1 electrically connects with the generative circuit 21a of odd-numbered line, second group of clock cable 22a2 and idol

Clock cable m2, in order to avoid the complexity of accompanying drawing, being only presented in Fig. 5 every group of clock cable includes two clocks letters
Number line, and in Fig. 2, Fig. 4 and Fig. 6, does not provide the concrete structure of every group of clock cable, only with a clock cable come
Represent one group of clock cable；Further, in the structure shown in Fig. 7 a, in the pixel cell that working condition is dispaly state
11 are：When 11-6,11-8,11-14 and 11-16, and the thin film transistor (TFT) in pixel cell 11 in pixel control circuit is N
During type, the normal periodic clock signal of generative circuit 21a inputs of first group of clock cable 22a1 to odd-numbered line, control
The generative circuit 21a of odd-numbered line processed is to corresponding LED control signal line 12a input high level signals, so that the pixel of odd-numbered line
The pixel control circuit of unit 11 is in running order；And second group of clock cable 22a2 is to the generative circuit 21a of even number line
Non- clock signal is inputted, such as low level signal (if the thin film transistor (TFT) for forming generative circuit 21a is N-type), controls even number line

When 21b is to corresponding data signal line 12b input data signals, control line 22 inputs to the grid of three switching transistors respectively
High level signal, so that three switching transistors turn in turn；And work as and do not need multiplexer circuit 21b to believe to corresponding data
During number line 12b input data signals, control line 22 is respectively to the grid input low level signal of three switching transistors, so that three
Individual switching transistor is all ended.
Also, in the structure shown in Fig. 7 a, in order to avoid the complexity of accompanying drawing, only represent one group with a clock cable
Clock cable, one group of thread switching control only is represented with a thread switching control, and son is not showed that in pixel cell 11
Pixel cell；Switching transistor conducting in the multiplexer circuit 21b of first group of control line traffic control odd column, by data-signal
Output is to corresponding data signal line 12b, so that the pixel control circuit of the pixel cell 11 of odd column is in running order；The
Switching transistor cut-off in the multiplexer circuit 21b of two groups of control line traffic control even columns, not to corresponding data signal line
12b input data signals, so that the pixel control circuit of the pixel cell 11 of even column is in off working state；Therefore, each
In the case of multiplexer circuit 21b structure identical, first group of thread switching control 22b and second group of thread switching control 22b, point
When not there is the switch controlling signal of different sequential to corresponding multiplexer circuit 21b inputs, two groups of multichannels choosings can be controlled
Select the different signal of circuit output.
Therefore, generative circuit 21a and multiplexer circuit 21b control are passed through, it is ensured that the picture without display image
