Preferably, the right gate driver and the gate driver are connected in series on the output terminal of the chip. Preferably, when the left gate driver is separately connected to the other output end of the chip for use, the horizontal scanning line is designed in a normal linear mode, a bilateral driving device is adopted, and the right gate driver cannot conduct signals to the left due to special-shaped cutting, but the right gate driver can normally display the signals because corresponding gate driving signals are provided on the left; the sizes of the cuts are different, and the redesign and routing of the horizontal scanning lines are not caused.
Description
Technical Field
The utility model relates to a display screen technical field specifically is a bilateral drive can various display screen of dysmorphism cutting.
Background
At present, the display of the mobile phone is required to be full display, the screen occupation ratio is larger and larger, but the front face of the mobile phone is added with necessary electronic elements such as a camera, a receiver and the like, the idea of a special-shaped screen is generated, the screen occupies the whole front face, and the screen part at the positions of the camera and other elements is cut off. Thus, the horizontal scan line is avoided at the cut, and the curve is connected to another display scan line. If the cutting area is different, different wiring designs are needed to meet the requirements.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a bilateral drive can various special-shaped cutting display screen, uses the back, promotes the productivity and reduces product cost.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a bilateral drive can various special-shaped cutting display screen, includes the display screen main part to and set up the gate driver in the display screen main part, the left and right sides of display screen main part still electric connection have right gate driver and left gate driver respectively, and still be provided with the chip in the display screen main part.
Preferably, the right gate driver and the gate driver are connected in series on the output terminal of the chip.
Preferably, the left gate driver is separately connected to the other output terminal of the chip.
The utility model provides a bilateral drive can various display screen of dysmorphism cutting. The method has the following beneficial effects:
(1) when the double-side drive display screen capable of being cut in various special shapes is used, the horizontal scanning lines are designed according to a normal straight line mode, the double-side drive device is adopted, signals cannot be conducted to the left side due to special-shaped cutting of the right side grid drive, and the right side can be displayed normally due to the fact that corresponding grid drive signals are provided on the left side; the sizes of the cuts are different, and the redesign and routing of the horizontal scanning lines are not caused.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The current mainstream display screen is a TFT-LCD display screen, TFT liquid crystal is provided with a semiconductor switch for each pixel, and each pixel can be directly controlled through point pulse, so that each node is relatively independent and can be continuously controlled, the reaction speed of the display screen is improved, the display color level can be accurately controlled, and the color of the TFT liquid crystal is more true.
The chinese name of TFT LCDs is called thin film transistor liquid crystal displays. The following diagram is a display driving principle diagram, wherein 1-1 is a thin film transistor, 1-2 is a liquid crystal capacitor, one pixel point is controlled, and Sn is a source driver which is a data signal; gn is Gate driver, which is a Gate control signal; the thin film transistor 1-1 is only a switch, and it mainly determines whether the voltage from the LCD source driver is charged to the pixel, how high the voltage is charged to the pixel, and controls the liquid crystal turning direction of the pixel to display what gray scale to form different colors.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a bilateral drive can various special-shaped cutting display screen, includes display screen main part 1 to and set up grid driver 4 in display screen main part 1, the left and right sides of display screen main part 1 still electric connection has right grid driver 2 and left grid driver 3 respectively, and still is provided with chip 5 in the display screen main part 1.
Wherein: the right gate driver 2 is connected in series with the gate driver 4 at the output of the chip 5. The left gate driver 3 is connected solely to the other output terminal of the chip 5.
At present, a driving wire for horizontal scanning of a mobile phone liquid crystal display screen is connected to an external IC to control and complete, and the drive IC controls the gradual charging and discharging of horizontal scanning lines at all levels; the row-by-row delivery of data on the data lines is also controlled. By using the GOA technology, the driving circuit of the horizontal scanning line can be manufactured on the substrate around the display area on the original manufacturing process of the liquid crystal display panel, so that the driving circuit can replace an external IC to complete the driving of the horizontal scanning line. The GOA technology can reduce binding (bonding) procedures of an external IC, has an opportunity to improve productivity and reduce product cost, and can enable the liquid crystal display panel to be more suitable for manufacturing narrow-frame or frameless display products.
In this embodiment, the horizontal scanning line is designed in a normal linear manner, and a bilateral driving device is adopted, so that the right gate drive cannot conduct signals to the left due to the special-shaped cutting, but the right gate drive can normally display due to the corresponding gate drive signals provided on the left; the sizes of the cuts are different, and the redesign and routing of the horizontal scanning lines are not caused.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
