Detailed Description
The invention aims to provide a pixel circuit, a display device and a control method thereof, which can effectively overcome the limitation of the maximum frequency of a circuit working component on the frame rate and the gray scale number and improve the picture display quality.
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a display device according to the present invention includes a column control module 100, a row control module 200, and a display array formed by a plurality of pixel circuits 300, wherein the plurality of pixel circuits form the display array in a matrix array manner, and the column control module 100 and the row control module 200 are both connected to the pixel circuits 300; the column control module 100 is used for providing a data signal for each column of the pixel circuits 300 in the display array; the row control module 200 is configured to provide a scan signal and a control signal for each row of the pixel circuits 300 in the display array, and control the pixel circuits 300 to write a data signal in a data writing stage and to light up according to the data signal in a display stage.
Specifically, when the row control module 200 outputs the scan signal to the pixel circuit 300 and the column control module outputs the data signal to the pixel circuit 300 for scanning and writing the data signal, i.e. performing a scanning process or an addressing process, the row control module 200 controls the pixel circuit 300 not to be turned on; compared with the traditional scanning process, once the scanning signal is input, the display state of the corresponding pixel circuit 300 is changed immediately, the scanning of the used line must be completed within the shortest sub-field time at the moment, otherwise, the next sub-field can be interfered, the pixel circuit 300 is controlled not to be lightened in the data writing stage in the application, the pixel module is lightened in the display stage, the addressing process, namely the data writing stage and the display stage are independent, so the lightening process cannot be influenced in the addressing process, the addressing process is more sufficient, the lightening duration time can be shorter, namely the shortest sub-field length can be shorter, the corresponding frame rate and the gray scale number can be higher, the limitation of the working frequency of circuit working components on the frame rate and the gray scale number can be avoided, and the display quality is improved.
Further, referring to fig. 2, the row control module 200 includes a first shift register 210 and a second shift register 220, and both the first shift register 210 and the second shift register 220 are connected to the pixel circuit 300; the first shift register 210 is configured to provide a scan signal for each row of the pixel circuits 300 in the display array, and control the pixel circuits 300 to write the data signal in a data writing phase; the second shift register 220 is configured to provide control signals for each row of the pixel circuits 300, control the pixel circuits 300 to be turned on in a display stage according to the data signals, and control the control signal of each row to be delayed by one clock compared with the control signal of the previous row, so as to reduce a response speed of a power supply of each pixel circuit 300 and reduce a design difficulty of the power supply.
Referring to fig. 3 and fig. 4, in this embodiment, a display matrix with 5 rows by 3 columns is taken as an example for illustration, the corresponding row control module 200 outputs 5 control signals to the display array, each row of the pixel circuits 300 corresponds to one control signal, and the control signal of each row is delayed by one clock compared with the control signal of the previous row, which is equivalent to shifting the level of the current row to the next row by one pulse time of the second shift register 220, where the pulse time is consistent with the shortest sub-field time length; if the timing sequences of the control signals of each row are the same, each time the addressing stage and the display stage are switched, the power supply of the pixel circuit 300 must be turned on or completely turned off, and at this time, the state of the power supply must be suddenly changed and stabilized in a short time, and the corresponding load needs an adaptive power supply; in this embodiment, the second shift register 220 delays the control signal of each row by one clock compared to the control signal of the previous row, so that the power supply does not need to change greatly in a short time, and a time slow transition occurs from the minimum voltage value to the maximum voltage value, where the time slow transition is the shortest subfield length with the shortest time length multiplied by the total number of rows; therefore, the timing sequence of the control signal in the embodiment enables the power supply not to bear great load conversion instantly, and correspondingly, the power supply not to adapt to high-speed load change is not needed, so that the difficulty of power supply design is reduced.
