Description

a display panel

Technical field

The invention belongs to the field of display technology, and particularly relates to a display panel.

Background technique

The display panel mainly includes three parts: pixel structure (generally including RGB sub-pixels), pixel driver and panel substrate. In the existing production process, the pixel structure is independently packaged and completed by the lamp bead manufacturer; the display panel manufacturer designs the panel row control scheme, prepares the driver substrate (specifically including installing the pixel driver on the panel substrate), and then packages the The lamp beads (i.e. pixel structure) are welded and processed to produce a finished display panel. In the display panel production industry, the division of production work is clear and the system is complete. Under this mature and traditional production model, the shortcomings of display panels are also exposed.

Since the pixel structure and pixel driver are produced independently and then packaged, when several pixel structures are packaged on a panel substrate, sufficient area needs to be reserved to install the pixel driver. As shown in Figure 3, generally the pixel structure 10 is arranged in an array distribution. An area is reserved between the pixel structures of two adjacent columns for the installation of pixel drivers, which makes the transition gap 20 between the pixel structures of two adjacent columns larger, causing the display panel to move when the display elements are translated during the display process. Jumping and smearing problems occur. Since each component is produced independently, it is difficult for panel substrate manufacturers to solve this problem by controlling the distance between pixel structures when packaging. Furthermore, in existing display panels, the RGB sub-pixels are arranged in the same way among several pixel structures, resulting in poor interactivity between sub-pixels in the pixel structure, and only a single pixel structure can be used as a pixel. For display, when the display elements are translated, the distance between pixels is large, which also highlights the problems of display jumping and smearing.

Therefore, the existing technology needs to be improved and developed.

As shown in Figure 1, a display panel of the present invention includes:

substrate 100;

Several pixel structures 200 are arranged in an array on the substrate 100. The plurality of pixel structures 200 are divided into a first pixel structure 201 and a second pixel structure 202 that are upper and lower mirror images of each other. The plurality of pixel structures 200 are arranged in an array. Among the plurality of pixel structures 200, the pixel structures 200 in odd-numbered columns are the first pixel structure 201, the pixel structures 200 in even-numbered columns are the second pixel structure 202, or the pixel structures 200 in odd-numbered columns are the second pixels. Structure 202, the pixel structure 200 of the even-numbered columns is the first pixel structure 201;

In specific applications, according to application requirements, the substrate 100 has been routed using existing technical means to electrically connect with the pixel structure 200. According to the pixel structure 200 of the odd-numbered columns is the first pixel structure 201, and the pixel structure 200 of the even-numbered columns is The second pixel structure 202, or the pixel structures 200 in odd-numbered columns are the second pixel structure 202, and the pixel structures 200 in the even-numbered columns are the first pixel structure 201. Several pixel structures 200 are packaged in an array distribution on the substrate 100, And the distance between the pixel structures 200 is appropriately adjusted to ensure the display effect. In this technical solution, three sub-pixels 211 of an originally independent pixel structure 200 form a pixel point. Between two adjacent pixel structures 200, the sub-pixels 211 of different pixel units can also form a pixel point across units, so that in a specific When displaying, the display element does not translate with one pixel unit as the basic unit, but with one sub-pixel 211 as the basic unit, which greatly reduces the translation distance of the display element, thereby effectively solving the problem of jumping and smearing when the display element is translated. , significantly optimizing the display effect of the display panel. Any sub-pixel 211 can be reused in a total of six pixels above, below, left, and right (i.e., six isosceles triangle structures 300). While improving the utilization rate of a single point, the interaction between the sub-pixels 211 is realized. Specific to this embodiment, the pixel structure 200 in the odd-numbered columns is the first pixel structure 201, the pixel structure 200 in the even-numbered columns is the second pixel structure 202, and the three sub-pixels 211 in each pixel unit are R sub-pixels 211 and G respectively.

In specific applications, through this technical solution, when encapsulating the pixel structure, in the row direction, the interaction between the pixel structures can be accurately realized by arranging the pixel structures one after another in the row direction, without the need to separately adjust the distance between the pixel structures.

Further, it is beneficial to the pixel structure 200 to make the first distance L1=the second distance L2, or the third distance L3=the fourth distance L4, or the first distance L1=the second distance L2=the third distance L3=the fourth distance L4. In the integrated package of the pixel unit and the pixel driver, when three pixel units and three pixel structures 200 are staggered and arranged side by side, there is even and sufficient space between each sub-pixel 211 to install the pixel driver.

Through this solution, the area between the sub-pixels 211 and the sub-pixels 211 can be used to stagger the sub-drivers 221 corresponding to each sub-pixel 211, which can fully utilize the space and make the pixel structure 200 and even the display panel more concise. At the same time, the sub-drivers 221 and The sub-pixels 211 are arranged in parallel, which is more convenient for the setting of the MOTFT driving circuit when the driving circuit is used.
