Description
Technical field
The present invention relates to field of display, and in particular to a kind of Novel low power consumption TFT display.
Background technique
Universal with wearable product and low power dissipation electron price tag, user is higher and higher to the power consumption requirements of product,
Middle display module is a factor for influencing power consumption.
In existing pixel-driving circuit, with pixel-driving circuit collocation IC integrated circuit in for pixel driver electricity
The Soure Pin of the Source line conveying signal on road in no power transmission, is somebody's turn to do in the voltage for being grounded or retaining last line
Design will lead to increasing for electric leakage, especially at low frequencies, power saving and good display effect be not achieved.Therefore it provides a kind of
The Novel low power consumption TFT display to solve the above problems is with regard to necessary.
Summary of the invention
The technical problem to be solved by the present invention is to the technologies existing in the prior art in the presence of electric leakage, power saving effect difference to ask
Topic.A kind of new Novel low power consumption TFT display is provided, the Novel low power consumption TFT display with drain conditions imitate by few, power saving
The good feature of fruit.
In order to solve the above technical problems, the technical solutions adopted are as follows：
A kind of Novel low power consumption TFT display, the Novel low power consumption TFT display include multiple pixels, and are used for pixel
The pixel-driving circuit of driving, the pixel-driving circuit include Source line, are connected with switch on the Source line；It is described
Switch the open and-shut mode for controlling corresponding Source line.
The working principle of the invention：In the present invention, when needing picture to drive, Gaten+1 and need GATE to be used are same
When open, and demand close when, Gaten+1 is also closed together with other gate line.To reduce the electric leakage of Source line
It may.
In above scheme, for optimization, further, the switch is TFT transistor.
Further, the grid of the TFT transistor is connect with Gate line, and the drain electrode of TFT transistor and source electrode connect respectively
It connects at the both ends of Gate line.
Further, peak voltage VGM=5V, peak voltage VGL=- 5V fluctuation voltage are applied on the Gate line.
Further, the spike of the fluctuation voltage is 0-10.
Further, the TFT transistor is located at outside the pixel of Novel low power consumption TFT display.
Beneficial effects of the present invention：
The Source PIN of the existing IC to arrange in pairs or groups with common PANEL is substantially at GND or HIGH or guarantor in no power transmission
The voltage for staying last line will lead to increasing for electric leakage；The present invention is in existing TFT design basis in every Source line
A upper plus TFT transistor reduces pixel electric leakage, normally shows at low frequency 0.1-40Hz to reach as switch.
The present invention is when frame frequency is less than 10HZ, and when Gate is in and closes, voltage or plus one can be not added at the end GATE
The fluctuation voltage of a VGM=5V or so, VDL=- 5V or so, the spike of fluctuation voltage can be 0 ~ 10, to prevent TFT cracking.
Although more TFT series connection can reduce electric leakage, if added in TFT pixel, aperture opening ratio can be reduced and reduce transmission
Rate or the light of reflection reach more effect with aperture opening ratio to leak electricity, TFT switch pipe are moved out to outside pixel, do not occupy effect
Display area；Aperture opening ratio can be had both and reduce electric leakage.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit
The fixed present invention.
Embodiment 1
The present embodiment provides a kind of Novel low power consumption TFT display, the Novel low power consumption TFT display includes multiple pixels,
And the pixel-driving circuit for pixel driver, the pixel-driving circuit include Source line, are connected on the Source line
It is connected to switch；The open and-shut mode switched for controlling corresponding Source line.The other parts of display are all made of existing
Technology.
Such as Fig. 1, the switch is TFT transistor.Specifically, the grid of the TFT transistor is connect with Gate line, TFT
The drain electrode of transistor and source electrode are connected to the both ends of Gate line.
Such as Fig. 2, peak voltage VGM=5V, peak voltage VGL=- 5V fluctuation voltage are applied on the Gate line.Specifically
Ground, the spike of fluctuation voltage are 0-10.
Leak electricity vacancy rate and aperture opening ratio in order to balance, it is preferable that the TFT transistor is located at Novel low power consumption TFT and shows
Outside the pixel of device.
It is the existing electric leakage schematic diagram and embodiment 1 that electric leakage processing is not carried out to Source line such as Fig. 3-Fig. 5
In the TFT switch pipe that increases Source line synchronized as switch cut-off the electric leakage effect diagram of control, and apply
The electric leakage effect diagram of fluctuation voltage.Wherein 1TFT No destress corresponds to existing design, 1TFT+SourceTFT
Corresponding is the design for only adding TFT switch pipe, and 1TFT+SourceTFT+destress corresponding is TFT switch pipe and fluctuation electricity
The design of pressure.
According to result it is found that the effect for improving electric leakage is 1TFT+Source TFT>1TFT+source TFT+Destress
>1TFT NO destress。
Although the illustrative specific embodiment of the present invention is described above, in order to the technology of the art
Personnel are it will be appreciated that the present invention, but the present invention is not limited only to the range of specific embodiment, to the common skill of the art
For art personnel, as long as long as various change the attached claims limit and determine spirit and scope of the invention in, one
The innovation and creation using present inventive concept are cut in the column of protection.
