Description

Display panel and display device thereof Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display panel and a display device thereof. Background Art

[0002] In the field of display technology, for example, the pixel array of a liquid crystal display panel or an organic light emitting diode (OLED) display panel usually includes multiple rows of gate lines and multiple columns of data lines interlaced therewith. The driving of the gate lines can be achieved by a bound integrated drive circuit. In recent years, with the continuous improvement of the preparation process of amorphous silicon thin film transistors or oxide thin film transistors, the gate line drive circuit can also be directly integrated on the thin film transistor array substrate to form a GOA (Gate driver On Array) to drive the gate lines. For example, a GOA composed of multiple cascaded shift register units can be used to provide scanning signals for multiple rows of gate lines in a pixel array, so as to control the multiple rows of gate lines to open in sequence, and at the same time, the data lines provide data signals to the pixel units of the corresponding rows in the pixel array to form the grayscale voltage required for each grayscale of the displayed image in each pixel unit, thereby displaying a frame of image. Current display panels are increasingly using GOA technology to drive the gate lines. GOA technology helps to achieve a narrow frame design for the display panel and can reduce the production cost of the display panel.

[0079] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. And in the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0080] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0081] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual scale and are only for the purpose of illustrating the present invention. The same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0082] In some embodiments of the present disclosure, the display device may include a display panel and a timing controller. The display panel may include a substrate (i.e., an array substrate), and the substrate may include a display area and a non-display area. The display area may include a plurality of pixel units arranged in an array. Exemplarily, each pixel unit includes sub-pixels of multiple different colors. For example, a pixel unit may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel, so that red, green, and blue can be mixed to achieve color display. Alternatively, the pixel unit may also include a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel, so that red, green, blue, and white can be mixed to achieve color display. Of course, in actual applications, the luminous color of the sub-pixels in the pixel unit can be designed and determined according to the actual application environment, and is not limited here.

[0083] In some embodiments of the present disclosure, the display area may further include multiple gate lines and multiple data lines. Each sub-pixel may include a transistor and a pixel electrode. Among them, a row of sub-pixels corresponds to a gate line, and a column of sub-pixels corresponds to a data line. The gate of the transistor is coupled to the corresponding gate line, the source of the transistor is coupled to the corresponding data line, and the drain of the transistor is coupled to the pixel electrode. It should be noted that the pixel array structure of the present disclosure can also be a dual-gate structure, that is, two gate lines are set between two adjacent rows of pixels. This arrangement can reduce half of the data lines, that is, some data lines are included between two adjacent columns of pixels, and some data lines are not included between two adjacent columns of pixels. The specific pixel arrangement structure and data lines, and the arrangement of the gate lines are not limited.

[0084] In some embodiments of the present disclosure, the non-display area may include a gate drive circuit and a source drive circuit. The gate drive circuit is coupled to the gate line, and the source drive circuit is coupled to the data line. In addition, the timing controller may be coupled to the gate drive circuit and the source drive circuit, respectively. Generally, the gate drive circuit is arranged in the non-display area on the left and right sides of the display panel. For example, the timing controller can obtain the display data of the picture to be displayed in the current display frame, and the timing controller can input a control signal to the gate drive circuit so that the gate drive circuit can output a gate scan signal to each gate line according to the input control signal, thereby driving each gate line to control the transistor conduction in the coupled sub-pixel. In addition, the timing controller inputs the acquired display data to the source drive circuit so that the source drive circuit can input a data voltage to the coupled data line according to the input display data, thereby inputting the voltage on the data line into the sub-pixel through the turned-on transistor to charge the sub-pixel, thereby charging each sub-pixel with the corresponding data voltage to realize the picture display function.

[0085] It should be noted that the display panel in the embodiment of the present disclosure may be a liquid crystal display panel. Exemplarily, the liquid crystal display panel generally includes an upper substrate (e.g., a color filter substrate) and a lower substrate (e.g., a substrate substrate) of the pair of boxes, and liquid crystal molecules encapsulated between the upper substrate (e.g., a color filter substrate) and the lower substrate (e.g., a substrate substrate). When displaying a picture, since there is a voltage difference between the data voltage loaded on the pixel electrode of each sub-pixel and the common electrode voltage on the common electrode, the voltage difference can form an electric field, thereby causing the liquid crystal molecules to deflect under the action of the electric field. Due to different intensities of electric fields, the degree of deflection of the liquid crystal molecules is different, resulting in different transmittances of the sub-pixels, so that the sub-pixels achieve different grayscale brightness, thereby realizing picture display. Of course, the display panel in the embodiment of the present disclosure may also be an OLED display panel, which is not limited here.
