Description
Technical Field
The present invention relates to the field of display technologies, and in particular, to a display device, a display system, and a manufacturing method.
Background
The Liquid crystal display device (Liquid CRYSTAL DISPLAY, LCD) and the Organic Light-Emitting Diode (OLED) display device occupy the dominant position in the field of flat panel display because of the advantages of stable picture, vivid image, radiation elimination, space saving, energy consumption saving, etc. The display panel of the display device is provided with a plurality of scanning lines and data lines, and the scanning lines or the data lines extend to the edge of the display panel to form leads for connection with the driving chip. Because of the huge number of scan lines and data lines, the conventional soldering process is difficult to process, and therefore, a Chip On Film (COF) packaging process is generally used to connect the display panel with the driving Chip.
The flip chip film packaging process is a technique for bonding an integrated circuit (INTEGRATED CIRCUIT, IC) chip to a display panel using a flexible circuit board as a carrier. In the COF packaging process, since the driving chip does not occupy a part of the area of the display panel, the resolution of the display device of the COF packaging process is higher and the frame is narrower than that of the COG (Chip On Glass) packaging process.
Fig. 2a and 2b show schematic diagrams of the connection of display devices at different resolutions, respectively, according to the prior art. In the prior art, the first electrode array 121 located on the driving chip and the second electrode array 122 located on the base film are in one-to-one correspondence, and different connection methods are adopted between the third electrode array 113 located on the display panel and the second electrode array 122 located on the base film according to different resolutions.
As shown in fig. 2a, taking a display panel with a resolution of 480×480 and an RGB color mode as an example, a data selector (multiplexer) is used, and the display panel needs 240 channels. The first electrode array 121 includes electrodes S1 to S240, the second electrode array 122 includes electrodes P1 to P240, and the electrodes S1 to S240 are respectively in one-to-one correspondence with the electrodes P1 to P240. The third electrode array 113 on the display panel includes electrodes D1 to D240, and the electrodes D1 to D240 are respectively in one-to-one correspondence with the electrodes P1 to P240, so that the driving chip is connected to the display panel via the base film, and the display panel has 240 effective signal channels.
As shown in fig. 2b, taking a display panel with resolution of 454×454 and RGB color mode as an example, a data selector of six is adopted, so that 227 channels are required for the display panel. The first electrode array 121 includes electrodes S1 to S240, the second electrode array 122 includes electrodes P1 to P240, and the electrodes S1 to S240 are respectively in one-to-one correspondence with the electrodes P1 to P240. The third electrode array 113 on the display panel includes electrodes D1 to D227, and the electrodes D1 to D227 are respectively in one-to-one correspondence with the electrodes P7 to P233, so that the driving chip is connected to the display panel via the base film, and 227 effective signal channels are provided between the display panel and the driving chip.
However, with the increasing resolution of the display panel, the I/O ports of the driving chip are more and the density is greater, and the first electrode located on the driving chip and the second electrode located on the base film in the prior art are in one-to-one correspondence, so that the problem that the wiring density of the first electrode and the second electrode is too high, and the short circuit, the leakage, the circuit misconnection or the coupling capacitance increase caused by the too high line density of the display device due to insufficient process precision is easily generated.
Accordingly, there is a need for further improvements in the display devices of the prior art to solve the above-mentioned problems.
