Example one
Referring to fig. 2 and fig. 3 together, fig. 2 is a schematic structural diagram of a display device according to an embodiment of the present invention; fig. 3 is a schematic structural diagram of a display device including a gamma voltage chip according to an embodiment of the present invention. The display device comprises a display panel 1, a plurality of transmission circuit boards 2, a plurality of source electrode chip on films 3 and bridging wires 4. Each transmission circuit board 2 is connected to the display panel 1 through a plurality of source electrode flip-chip films 3 which are arranged at the edge of the display panel 1 in parallel; the transmission circuit board 2 is provided with transmission wires 5, and the transmission wires 5 are used for transmitting various driving signals and control signals to the display panel through the source electrode chip on film 3, that is, the various driving signals and control signals from the transmission circuit board 2 or through the transmission circuit board 2 need to be transmitted to the display panel 1 through the source electrode chip on film 3.
Further, at least one of the transmission circuit boards 2 is provided with a functional chip 6, and the functional chip 6 is connected to the other transmission circuit boards 2 through a connection line of the transmission trace 5 and the bridging trace 4. Specifically, since the display device includes a plurality of transmission circuit boards 2, each transmission circuit board 2 may be provided with a different functional chip 6, and different transmission circuit boards 2 need to be electrically connected to each other to transmit the functional signal of the functional chip 6.
The bridging trace 4 is used to electrically connect adjacent transmission circuit boards, specifically, two ends of the bridging trace 4 are respectively connected to the transmission traces 5 on the adjacent transmission circuit boards 2, and the bridging trace 4 includes a first bridging portion 41 disposed on the display panel 1 and a second bridging portion 42 disposed on the source electrode flip-chip film 3. Preferably, the first bridging portions 41 are etched on the scale substrate of the display panel 1.
As mentioned above, in the prior art, the routing between the adjacent transmission circuit boards usually needs to pass through the timing controller and the connector, and such a routing manner would occupy more channels on the connector and occupy more routing space on the timing control board. The bridging wires 4 of the present embodiment can utilize the vacant space on the display panel and the redundant pins on the source electrode flip-chip film to perform the wire routing, and do not occupy the channel on the connector and the wire routing space on the timing control board.
Further, as shown in fig. 3, the display device of the present embodiment includes a first transmission circuit board 21 and a second transmission circuit board 22, and the plurality of source flip-chip films 3 include a first source flip-chip film group 31 connected to the first transmission circuit board 21 and a second source flip-chip film group 32 connected to the second transmission circuit board 22, where the first source flip-chip film group 31 and the second source flip-chip film group 32 respectively include a plurality of source flip-chip films. The first transmission circuit board 21 is provided with a first transmission line 51, the second transmission circuit board 22 is provided with a second transmission line 52, and the first transmission line 51 and the second transmission line 52 are connected through the bridging line 4.
If the functional chip 6 is disposed on the first transmission circuit board, a part of the functional signal output by the functional chip 6 is directly transmitted to the display panel from the source electrode flip-chip film through the first transmission wire 51, and the other part needs to be transmitted to the second transmission circuit board 22 from the first transmission circuit board 21 through the connection wires of the first transmission wire 51, the bridging wire 4 and the second transmission wire 52, and then transmitted to the display panel 1 from the second transmission circuit board 22 through the source electrode flip-chip film 3.
It should be noted that the bridging wires 4 of the embodiment of the invention penetrate through the glass substrate of the display panel 1, but the impedance of the wires on the glass substrate is usually large, which causes the signal strength of the signal passing through the bridging wires 4 to be different from the signal strength of the signal not passing through the bridging wires 4, thereby affecting the display uniformity of the display panel.
In order to solve the problem, the display device further includes a compensation trace 7, two ends of the compensation trace 7 are respectively connected to the transmission traces 5 on the same transmission circuit board 2, and the compensation trace 7 includes a first compensation portion 71 disposed on the display panel 1 and a second compensation portion 72 disposed on the adjacent source electrode flip-chip film 3.
Specifically, the compensation trace 7 may be disposed between any two adjacent source flip-chips 3 connected to the first transmission circuit board 22, i.e., the second compensation portion 72 may be disposed on any two adjacent source flip-chips 3 connected to the first transmission circuit board 22.
In this embodiment, the bridging trace 4, the transmission trace 5 and the compensation trace 7 are all metal wires, such as copper wires.
The trace of the Gamma voltage chip (Gamma IC) will be taken as an example to illustrate the trace of the display device. In the present embodiment, a gamma voltage chip is disposed on the first transmission circuit board 21 for providing a reference voltage for each pixel unit in the display panel, and an output signal thereof needs to be transmitted to each pixel unit (not shown in the drawings) on the display panel 1 via each source flip-chip 3.
Specifically, the output terminal of the gamma voltage chip is connected to a first transmission trace 51 on the first transmission circuit board 21, and is communicated with a second transmission trace 52 on the second transmission circuit board 21 through the bridge trace 4. In the signal transmission process, the output signal from the gamma voltage chip is directly transmitted to each source electrode flip-chip film in the first source electrode flip-chip film group 31 through the first transmission wiring 51, and then transmitted to the pixel unit on the left side of the display panel through the corresponding data line connecting the source electrode flip-chip film and the pixel unit; on the other hand, the reference voltage of the gamma voltage chip is distributed to each pixel unit in the display panel by the connection line of the first transmission line 51, the bridging line 4 and the second transmission line 52, which is transmitted to each source electrode flip-chip in the second source electrode flip-chip package 32, and then transmitted to the pixel unit on the right side of the display panel by the corresponding data line.
Since the impedance of the wires on the glass substrate of the display panel is usually high, the reference voltage may generate a large voltage drop after passing through the bridging wire 4, and finally the brightness of the left and right pixel units on the right side is affected, which may cause the split screen phenomenon. Therefore, for the transmission of the reference voltage, the compensation trace 7 is connected to the first transmission trace 51, and as can be seen from the above description, the layout modes of the compensation trace 7 and the bridge trace 4 in this embodiment are the same, and a part of the compensation trace 7 and the bridge trace 4 are both disposed on the display panel with a relatively large impedance, so that the impedances of the voltage reference signal passing through the first transmission trace 51 and the second transmission trace 52 are the same, thereby improving the problem of left and right screen splitting of the display panel caused by the difference of the reference voltage.
The display device of the embodiment can utilize the vacant space on the glass substrate of the display panel and the redundant pins on the source electrode chip on film to route, does not occupy the channel on the connector, and does not occupy the routing space on the time sequence control board. In addition, the display device of the embodiment can utilize the vacant space on the glass to perform impedance compensation, is flexible in arrangement of the matching wires, and can solve the display problems of left and right split screens and the like caused by inconsistent impedance of the wires.
Example II,
The first transmission circuit board 21 of the display device of the present embodiment is provided with a second functional chip 62, wherein the second functional chip 62 is connected to one source flip-chip film in the first source flip-chip film set 31 through a first transmission trace 51; the second functional chip 62 is connected to one source flip-chip film in the second source flip-chip film group 32 through the connection lines of the first transmission lines 51, the bridge lines 4 and the second transmission lines 52.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a display device including a level shift chip according to an embodiment of the present invention, in which the second functional chip 62 is a level shift chip, and the routing of the level shift chip (L ev shift ic) is taken as an example to illustrate the routing of the display device in this embodiment, the level shift chip (L ev shift ic) is disposed on the first transmission circuit board 21, and at the same time, a first GOA (gate driver array) circuit board 8 and a second GOA circuit board 9 are disposed on two sides of the display panel 1, respectively, and the level shift chip is connected to the first GOA circuit board 8 and the second GOA circuit board 9, respectively, so as to provide clock signals for the first GOA circuit board 8 and the second GOA circuit board 9.
Further, the level shift chip is connected to the first GOA circuit board 8 through any one of the source flip-chip packages in the first source flip-chip package 31; the level shift chip is connected to the second GOA circuit board 9 through any one of the second group of source flip-chip packages 32.
In this embodiment, the output terminal of the level shift chip is connected to the first transmission trace 51 on the first transmission circuit board 21, and is communicated with the second transmission trace 52 on the second transmission circuit board 21 through the bridge trace 4. In the signal transmission process, the output signal from the level conversion chip is directly transmitted to the leftmost source chip on film in the first source chip on film group 31 through the first transmission wire 51, and then transmitted to the first GOA circuit board 8 through the source chip on film; on the other hand, the signal is transmitted to the rightmost source flip-chip package in the second source flip-chip package group 32 through the connection line of the first transmission trace 51, the bridging trace 4 and the second transmission trace 52, and then transmitted to the second GOA circuit board 9 through the source flip-chip package.
It should be noted that, since the impedance has a small influence on the transmission effect of the clock signal, when the clock signal is transmitted, the compensation trace 7 may not be disposed on the first transmission trace 51, for example, the compensation trace 7 indicated by a dotted line in fig. 4 may be eliminated.
The display device of the embodiment can utilize the vacant space on the glass and the redundant pins on the source electrode chip on film to route, so as to complete the transmission of the clock signal between the level conversion chip and the GOA circuit board, and the display device can not occupy the channel on the connector and does not occupy the routing space on the time sequence control board.
Further, the display device further includes a timing controller 10 and a plurality of connectors 11, and the timing controller 10 is connected to each of the transmission circuit boards 2 through the plurality of connectors 11, respectively.
Another embodiment of the present invention provides an electronic apparatus including the display device described in any one of the above embodiments.
