Description

Technical Field

[0001] This invention relates to the field of displays, and in particular to a composite display circuit, a control method, and a display device. Background Technology

[0002] Display devices typically include a substrate, which usually includes control circuitry and display circuitry. The display units are arranged in an array. The control circuitry includes a gate drive circuit, a source drive circuit, multiple scan lines, and multiple data lines. The display units are connected at the intersections of the multiple scan lines and multiple data lines. The gate drive circuitry provides gate drive signals to multiple pixel units through the multiple scan lines, and the source drive circuitry provides source drive signals to multiple pixel units through the multiple data lines.

[0003] In practical applications, display units often need to be connected to both scan lines and data lines simultaneously. To ensure stable control of the display units, the scan lines and data lines of each display unit are usually separated and connected individually to the control unit FPC / IC terminal of the control circuit. This results in the entire display device's substrate requiring a large amount of wiring and wiring space. Due to the encroachment on wiring space, the edges of the overall substrate also need to be thicker. Complex wiring can also make the lines prone to interference faults, limiting the overall number of display units and restricting the overall resolution. Summary of the Invention

[0004] The present invention aims to provide a composite display circuit, a control method, and a display device to solve the problem of redundant wiring connecting each display unit to the control unit in the prior art.

[0005] This invention provides a composite display circuit, comprising:

[0006] The display circuit includes multiple electrode blocks arranged in an array, and each electrode block includes multiple display units arranged in an array.

[0007] A control circuit, comprising a control unit and a transfer electrode, wherein the display unit is connected to the transfer electrode and the transfer electrode is connected to the control unit; the control unit is used to individually control the electrode block in the display circuit and to control the opening and closing of the display unit in the electrode block.

[0008] In one embodiment, the adapter electrode is connected to a baseline;

[0009] The baseline of the control circuit includes a horizontal baseline and a vertical baseline. The horizontal baseline connects to the display units of each row in the electrode block, and the vertical baseline connects to the display units of each column in the electrode block. Both the horizontal and vertical baselines are connected to the control unit of the control circuit. Each display unit is connected to both a horizontal baseline and a vertical baseline.

[0010] In one embodiment, in the control circuit, under the control of the control unit, the display units in the different electrode blocks can be connected to the same baseline.

[0011] In one embodiment, the horizontal baseline connects a row of display units in different electrode blocks, and the vertical baseline connects a column of display units in different electrode blocks; the control unit controls different electrode blocks individually.

[0012] In one embodiment, the control unit outputs a TP signal and / or an HVA signal to the adapter electrode to control the display unit in the display circuit.

[0013] In one embodiment, when the control unit outputs an HVA signal to the adapter electrode, the baseline connecting the adapter electrode and the display unit is turned on according to the timing of the HVA signal, transmitting the corresponding voltage to the connected display unit.

[0014] In one embodiment, the control unit outputs a verification signal to the transfer electrode, the verification signal including an HVA signal and a TP signal; the TP signal segment is inserted into each frame of HVA signal segment to form a frame of the verification signal.

[0015] In one embodiment, the baseline is at least one of the input of the source, the output of the source, the input of the gate, and the output of the gate.

[0016] The present invention also provides a display device, comprising:

[0017] A substrate, wherein a first surface of the substrate includes a first region for forming a display array and a second region for forming a driving circuit;

[0018] The first region is provided with a display circuit of any of the aforementioned composite display circuits; the second region is provided with a control circuit of any of the aforementioned composite display circuits.

[0019] The present invention also provides a control method for a composite display circuit, characterized in that the method is applied to any of the above-mentioned composite display circuits, and includes:

[0020] The control unit sends a first control signal to the electrode block, so that all display units in the electrode block can perform corresponding operations according to the first control signal;

[0021] The control unit sends a second control signal to the transfer unit, which then forwards the signal to the display unit in the corresponding electrode block, so that the display unit performs the corresponding operation according to the second control signal.

[0022] Beneficial effects: In this case, the display units in the display circuit are divided into multiple electrode blocks, which are individually controlled by the control unit in the control circuit, achieving batch collective control. This avoids excessive wiring between the control unit and the display unit, resulting in redundant wiring and a simpler overall wiring. At the same time, the introduction of electrode blocks ensures control by the control circuit while also ensuring the relative isolation and individual control of each display unit within each electrode block, avoiding mutual interference between the display units within each electrode block.

[0032] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, provides a detailed explanation of the specific implementation methods, steps, structures, features, and effects of a repair array circuit and display device proposed according to the present invention.

[0033] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with reference to the accompanying drawings. Through the description of the specific embodiments, a more in-depth and specific understanding can be gained of the technical means and effects adopted by the present invention to achieve its intended purpose. However, the accompanying drawings are for reference and illustration only and are not intended to limit the present invention.

[0034] First implementation method:

[0035] The first embodiment of the present invention provides a composite display circuit, such as... Figure 1 and Figure 2 As shown, it includes:

[0036] The display circuit 10 includes a plurality of electrode blocks 101 arranged in an array, and the electrode blocks include a plurality of display units 1011 arranged in an array.

[0037] The control circuit 20 includes a control unit 201 and a transfer electrode 202. The display unit 1011 is connected to the transfer electrode 202, and the transfer electrode 202 is connected to the control unit 201. The control unit 201 is used to individually control the electrode block 101 in the display circuit 10 and to control the opening and closing of the display unit 1011 in the electrode block 101.

[0038] In this case, the display units 1011 in the display circuit 10 are grouped, with each group forming an electrode block 101. Each electrode block 101 is individually connected to the control unit 201 in the control circuit 20 (not shown in the figure), thereby enabling the control unit 201 to uniformly control all display units 1011 in the electrode block 101. Simultaneously, the control unit 201 is also connected to all display units 1011 in the electrode block 101 via a transfer electrode 202, allowing the control unit 201 to control all display units 1011.

[0039] In practice, the connection between all display units 1011 and control unit 201 in this case is not direct, but is performed through adapter electrode 202. Control unit 201 can control more display units 1011 without many interfaces.

[0040] like Figure 1 As shown, the control unit only needs four first control lines to each adapter motor 202 to control all display units of the four electrode blocks 101. Each adapter electrode 202 is also connected to the display unit 1011 in the electrode block 101 via four second control lines. Therefore, Figure 1The wiring actually requires 4 first control lines and 16 second control lines. During wiring, only the space between each electrode block 101 needs to be considered. Furthermore, the control unit 201 does not need to have the 16 interfaces required by current technology; instead, it only needs 4 output ports. This saves wiring space and improves the overall control efficiency of the control unit 201.

[0041] Furthermore, the distribution between electrode blocks 101 is in an array, and the distribution between display units 1011 in electrode blocks 101 is also in an array, which ensures clear wiring, while further reducing the difficulty of overall wiring, reducing wiring length, and improving wiring efficiency.

[0042] In other words, this design divides the display unit 1011 in the display circuit 10 into multiple electrode blocks 101, which are individually controlled by the control unit 201 in the control circuit 20. This achieves batch collective control, avoiding excessive wiring between the control unit 201 and the display unit 1011, thus simplifying the overall wiring. Simultaneously, the introduction of electrode blocks 101 ensures control by the control circuit 20 while also guaranteeing the relative isolation and individual control of each display unit 1011 within each electrode block 101, preventing mutual interference between the display units 1011 within each electrode block 101.

[0043] In some examples, such as Figure 1 As shown, the transfer electrode 202 corresponds to the electrode block 101, and each electrode block 101 corresponds to a unique transfer electrode 202. The control unit 201 is connected to the display unit 1011 in the electrode block 101 through the transfer electrode 202. The transfer electrode 202, as an intermediate electrode, directly corresponds to the electrode block 101, which facilitates the collective control of the control unit 201.

[0044] In some examples, the transition electrode 202 corresponds to the display unit 1011, and multiple transition electrodes 202 are provided to ensure the connection between the display unit 1011 and the control unit 201. Specifically, operators typically share the same transition electrode 202 for multiple synchronously switched pixel units (display units 1011) to achieve synchronous switching control of these pixel units, while minimizing the number of transition electrodes 202 to improve the utilization rate of the substrate.

[0045] In some examples, such as Figure 3As shown, the display unit 1011 uses EQ modules for display, and the electrode block 101 composed of multiple EQ modules serves as the TP block; the adapter electrode 202 exists in the form of a baseline (G line), and the control unit 201 uses an FPC / IC, so the FPC / IC can control each TP block individually. Each TP block is connected to the control unit FPC / IC using metal mesh capacitive touch technology.

[0046] In some examples, the adapter electrode 202 is connected to the baseline; the baseline of the control circuit 20 includes a horizontal baseline and a vertical baseline, the horizontal baseline is connected to the display unit 1011 of each row in the electrode block 101, the vertical baseline is connected to the display unit 1011 of each column in the electrode block 101, the horizontal baseline and the vertical baseline are both connected to the control unit 201 of the control circuit 20, and each display unit 1011 is simultaneously connected to a horizontal baseline and a vertical baseline.

[0047] Specifically, such as Figure 3 As shown, the adapter electrode 202 exists in the form of a baseline, which adopts G lines (including G1 to G8 lines). The baseline includes a horizontal baseline (G1 to G4) and a vertical baseline (G5 to G8). The horizontal baseline (G1 to G4) controls the horizontal display unit EQ in a TP block, and the vertical baseline (G5 to G8) controls the vertical display unit EQ in a TP block.

[0048] Taking TP1 as an example, horizontal baseline G1 controls the first row of EQ modules (EQ1, EQ2, EQ3, EQ4) in TP1; horizontal baseline G2 controls the second row of EQ modules (EQ9, EQ10, EQ11, EQ12) in TP1; horizontal baseline G3 controls the third row of EQ modules (EQ17, EQ18, EQ19, EQ20) in TP1; and horizontal baseline G4 controls the fourth row of EQ modules (EQ25, EQ26, EQ27, EQ28) in TP1. Vertical baseline G5 controls the first column of EQ modules (EQ1, EQ9, EQ17, EQ25) in the TP1 block; vertical baseline G6 controls the second column of EQ modules (EQ2, EQ10, EQ18, EQ26) in the TP1 block; vertical baseline G7 controls the third column of EQ modules (EQ3, EQ11, EQ19, EQ27) in the TP1 block; vertical baseline G8 controls the fourth row of EQ modules (EQ4, EQ12, EQ20, EQ28) in the TP1 block.

[0049] Each EQ module in the TP block is controlled by two baselines simultaneously, for example, Figure 3EQ1 is controlled by both G1 and G5, while EQ18 is controlled by both G3 and G6. Each EQ module connects to two LCD Q switches: one connected to the horizontal baseline and the other to the vertical baseline. The EQ module changes its two LCD Q switches through the combined control of the horizontal and vertical baselines, thus altering the illumination mode of its circuit (either the overall EQ module is on or off). Each baseline is routed to the output port of the control unit FPC, which transmits control signals via the G-line.

[0050] In some examples, the display units in the different electrode blocks may be connected to the same baseline.

[0051] Considering that there is no information exchange between the electrode blocks, each electrode block TP area is connected to the notification unit FPC of the control circuit 20. Based on the aforementioned example, different electrode blocks can also be controlled using the same baseline. For example... Figure 3 As shown, the same baseline G1 may connect both the TP1 and TP3 blocks simultaneously. In this case, the same baseline is used to control the display units in different electrode blocks, thereby making full use of the baseline, minimizing the space occupied by the connecting lines in the substrate where the display circuit is located, reducing the space occupied by the connecting lines, and improving the overall utilization rate of the substrate.

[0052] The control method for electrode blocks connected to the same baseline can be to use different segments of a waveform to control different electrode blocks, or to use different rules to control different electrode blocks using the same segment of a waveform, and so on. For example, if the baseline transmits waveform a, the control of block TP1 takes the first half of the first cycle of waveform a, and the control of block TP2 takes the second half of the first cycle of waveform a.

[0053] In a further example, the horizontal baseline connects a row of display units 1011 in different electrode blocks 101, and the vertical baseline connects a column of display units 1011 in different electrode blocks 101; the control unit 201 controls different electrode blocks individually.

[0054] Specific examples Figure 3As shown, the horizontal baseline G1 in the baseline is connected not only to EQ1-EQ4 in block TP1, but also to EQ5-EQ8 in block TP3, EQ33-EQ36 in block TP2, and EQ37-EQ40 in block TP4. The vertical baseline G in the baseline is connected not only to EQ1, EQ9, EQ17, and EQ25 in block TP1, but also to EQ33, EQ41, EQ49, and EQ57 in block TP2, EQ5, EQ13, EQ21, and EQ29 in block TP3, and EQ37, EQ45, EQ53, and EQ61 in block TP4.

[0055] In some examples, the control circuit 20 further includes a control sub-circuit, with electrode blocks 101 corresponding to each other, and all display units 1011 in each electrode block 101 connected to the control sub-circuit. The control sub-circuit includes two LCD Q modules.

[0056] like Figure 3 In the composite display circuit shown, the control sub-circuits used by each baseline (G1~G8) in electrode block TP1 to control the EQ modules (EQ1~EQ4, EQ9~EQ12, EQ17~EQ20, EQ25~EQ28) are illustrated in the following diagram. Figure 4 As shown.

[0057] like Figure 4 As shown, the baselines connecting all EQ modules in the electrode block TP are connected to the control sub-circuit. Specifically, horizontal baselines G1 to G4 are connected to one LCD Q module (LCD Q module one), and vertical baselines G5 to G8 are connected to another LCD Q module (LCD Q module two). All EQ modules are controlled directly within the electrode block TP using the control sub-circuit, enabling baseline control over all EQ modules in the electrode block TP.

[0058] Compared to existing technologies, directly connecting the EQ module to the control unit FPC / IC via the G line results in dense wiring, prone to signal interference between lines, and with a large line occupancy, making it unsuitable for narrow-bezel products. Furthermore, integrating the TP function requires accommodating N EQ lines and M TP lines on the lower edge of the substrate, which is insufficient for the space constraints of narrow-bezel products (where N is the total number of EQ modules in the TP area of ​​the electrode block). Figure 3 (N=16).

[0059] In this example, the control subcircuit coordinates the combination of two LCD Q modules. After combining all the EQ modules in the electrode block TP, only 8 traces are needed to connect the EQ modules to the control unit FPC / IC. Furthermore, if the TP function is integrated, the lower edge of the substrate only needs to accommodate 8 gate lines (8 G lines) and M TP lines, which saves more space compared to N EQ lines.

[0060] In some examples, the distance between the arrayed electrode blocks in the display circuit is less than 5 μm, and the spacing between each display unit in the electrode block is less than or equal to 5 μm.

[0061] In practical applications, to ensure the touch performance of the electrode block (TP block), such as Figure 3 As shown, the size of each electrode block is usually maintained at 5000um*5000um, while each display unit (EQ module) is usually set to 1250um*1250um, and the block spacing between EQ modules is ≤5um.

[0062] In some examples, the control unit 201 outputs a TP signal and / or an HVA signal to the transfer electrode 202 to control the display unit 1011 in the display circuit 10.

[0063] Specifically, the control signal output by the control unit 201 to the display unit 1011 via the baseline can be a TP signal, an HVA signal, or a verification signal composed of a mixture of TP and HVA signals.

[0064] If the control unit 201 controls the display unit 1011 by transmitting an HVA signal, when the control unit outputs an HVA signal to the adapter electrode, the baseline connecting the adapter electrode and the display unit is opened according to the timing of the HVA signal, transmitting the corresponding voltage to the connected display unit. Specifically, as follows... Figure 3 and Figure 4 The baselines (G1 to G8) shown are turned on in sequence as G1 / G2 / G3 / G4 & G5 / G6 / G7 / G8, providing different voltages to the EQ modules connected to each baseline, thereby enabling the screen to display different numbers and text.

[0065] If the control unit 201 controls the display unit 1011 via the TP signal. Figure 3 and Figure 4 The baselines (G1 to G8) shown in the figure are activated simultaneously with G1 / G2 / G3 / G4 & G5 / G6 / G7 / G8. The FPC / IC provided by the control unit 201 provides the TP signal, thereby realizing the touch function of the screen.

[0066] If the control unit 201 controls the display unit 1011 jointly via the TP signal and the HVA signal, the control unit outputs a verification signal to the transfer electrode. This verification signal includes both the HVA signal and the TP signal. The TP signal segment is inserted after each frame of the HVA signal segment to form one frame of the verification signal. Figure 3 and Figure 4 The baselines shown (G1~G8) are turned on sequentially in the order of G1 / G2 / G3 / G4 & G5 / G6 / G7 / G8, and the transmitted signal is the verification signal. The voltage waveform of the verification signal is as follows. Figure 5 As shown, a TP signal is actually added to the end of each HVA segment to form a frame of verification signal. Typically, the refresh rate of each frame of verification signal is 60Hz, and the duration of each frame is 4.166ms.

[0067] In other examples, the differentiation of electrode blocks is set according to the user's actual application requirements. For example... Figure 6 As shown, taking a 14-inch display as an example, the required AA specification is 301.5936*188.496, and the resolution is 1920*3*1200.

[0068] The TP (Transformer Terminal) blocks of the electrode blocks are typically set to a size of 5mm*5mm. Depending on the required resolution, the TP blocks are divided as follows: 60 TP blocks and 240 EQ modules are set in the 1920° direction, and 38 TP blocks and 152 EQ modules are set in the 1200° direction. That is, there are a total of 60*38=2280 electrode blocks (TP blocks), and a total of 240*152=36480 EQ modules. Each electrode block contains 4*4=16 display units (EQ modules within the TP blocks).

[0069] Since each electrode block (TP block) requires 8 baselines (G lines), and different electrode blocks can share the same baseline, the corresponding 2280 electrode blocks can still only require 8 baselines. Each electrode block requires one TP line, so the 2280 electrode blocks require 2280 TP lines. Therefore, in this example, the required IC channels are 2280 (number of electrode blocks / number of TP blocks) and 8 (number of G lines required per electrode block).

[0070] Traditional wiring methods, where each EQ module is individually connected to the FPC / IC, require 36,480 IC channels in practical applications. In comparison, the solution provided by this invention in this example clearly uses fewer IC channels, saving overall board resources. Correspondingly, using the same number of IC channels, this solution can display numbers and text at higher resolutions.

[0071] Second implementation method:

[0072] The second embodiment of the present invention provides a composite display circuit. The difference between this embodiment and the first embodiment is that the baseline connection method is different.

[0073] In this example, the control circuit's baseline includes a horizontal baseline and a vertical baseline. The horizontal baseline connects some display units within the electrode block, and the vertical baseline connects some display units within the electrode block. Each display unit is connected to both a horizontal and a vertical baseline. Different horizontal baselines connect to different display units, and different vertical baselines also connect to different display units.

[0074] For example, Figure 3 In this configuration, the EQ modules connected by line G1 are not necessarily in the same row; they could be EQ1, EQ10, EQ19, and EQ28, located in different rows and columns. Similarly, the EQ modules connected by line G5 are not necessarily in the same column; for example, EQ4, EQ11, EQ18, and EQ25 could be in different rows and columns. During implementation, it is only necessary to connect the same EQ module to different horizontal and vertical baselines.

[0075] In some examples, such as Figure 7 As shown, the connection of the electrode block (TP region) can be specifically described as follows:

[0076] For 6 electrode blocks, each electrode block is equipped with 4 EQ modules, and each EQ module corresponds to a connection line. The connection ports below the display circuit 10 formed by the TP modules in the figure are as follows: port 1 is connected to EQ1, ... port 24 is connected to EQ24. According to the TP area, all EQ modules in the same electrode block are connected to the same FPC line. That is, lines 1, 2, 3, and 4 are connected to the same FPC line, lines 5, 6, 7, and 8 are connected to the same FPC line, lines 9, 10, 11, and 12 are connected to the same FPC line, ..., lines 21, 22, 23, and 24 are connected to the same FPC line.

[0077] If horizontal baseline G1 controls EQ1 in TP1 area, EQ5 in TP2 area, EQ6 in TP3 area, EQ13 in TP4 area, EQ17 in TP5 area, and EQ21 in TP1 area, then G1 connects lines 1, 5, 9, 13, 17, and 21.

[0078] In some examples, the baseline is at least one of the input of the source, the output of the source, the input of the gate, and the output of the gate.

[0079] Specifically, in practical applications, the connection between the FPC and the EQ module is as follows: Figure 3and Figure 7 As shown, it can appear at the input / output terminal of the S-line of the control, or at the input / output terminal of the G-line. Figure 3 and Figure 7 The diagram primarily illustrates how the FPC / IC controls the EQ module via the G-line. For example, Figure 8 As shown, the baseline uses a connection diagram of the source end. Figure 9 The baseline shown is a schematic diagram of the connection at the gate end.

[0080] Third implementation method:

[0081] A third embodiment of the present invention provides a display device, comprising: a substrate, wherein a first surface of the substrate includes a first region for forming a display array and a second region for forming a driving circuit; the first region includes a display unit array distributed therefrom; a display circuit as described in either the first embodiment or the second embodiment is provided in the first region; and a control circuit as described in either the first embodiment or the second embodiment is provided in the second region.

[0082] Fourth implementation method:

[0083] The fourth embodiment of this invention provides a control method for a composite display circuit, applied to the display circuit of any of the composite display circuits in the first and second embodiments, the method comprising:

[0084] The control unit sends a first control signal to the electrode block, so that all display units in the electrode block can perform corresponding operations according to the first control signal;

[0085] The control unit sends a second control signal to the transfer unit, which then forwards the signal to the display unit in the corresponding electrode block, so that the display unit performs the corresponding operation according to the second control signal.

[0086] In other words, the control unit directly controls all display units in the electrode block, and this control is performed as a whole on an electrode block basis; the control unit also indirectly controls the display units through the transfer unit, and this control is performed individually on a display unit basis.

[0087] For example, if the control unit needs to control the A1 display unit in electrode block A to light up only, the control unit first sends a first control signal to make all electrode blocks in A light up and the other electrode blocks turn off; then it sends a second control signal to the transfer unit corresponding to electrode block A, and the transfer unit forwards the second control signal to the display unit in electrode block A so that the A1 display unit lights up and the other display units turn off.

[0088] Regarding the control methods implemented in this regard, this case presents several examples as follows:

[0089] In the first example, the control unit directly sends a first control signal to control all signal receiving units / circuits in the electrode block. Only when the signal receiving units / circuits are operational can the display units within the electrode block be illuminated. The control unit sends a second control signal to the switching unit corresponding to the electrode block containing the target display unit. The switching unit then decomposes / forwards / processes the second control signal and sends it to the target display unit in the corresponding electrode block. If the switching unit can only forward the signal, each target unit in the electrode block can find its corresponding segment based on the timing of the forwarded second control signal and execute the operation corresponding to that segment. If the switching unit can decompose the signal, after receiving the timing of the second control signal, it decomposes the timing segment corresponding to each display unit and forwards it to the corresponding display unit, allowing the display unit to perform the operation based on that segment.

[0090] In the second example, the control unit directly controls all display units in the electrode block to light up through the first control signal, and controls a specific target display unit to keep lit up through the second control signal, while other unrelated target display units are turned off.

[0091] The switching unit controls the display unit in the electrode block according to the second control signal. Specifically, the switching unit exists in the form of a baseline, which includes a horizontal baseline and a vertical baseline. The horizontal baseline connects the display unit in each row of the electrode block, and the vertical baseline connects the display unit in each column of the electrode block. Each display unit is connected to both a vertical baseline and a horizontal baseline.

[0092] The second control signal will then be divided into two parts: a first part transmitted by the horizontal baseline and a second part transmitted by the vertical baseline. After the circuit corresponding to the motor block is turned on under the control of the first control signal, the display unit in the electrode block will simultaneously control itself according to the first and second parts of the received second control signal.

[0093] It is not difficult to see that this embodiment is a method embodiment corresponding to the first or second embodiment, and this embodiment can be implemented in conjunction with the first or second embodiment. The relevant technical details mentioned in the first or second embodiment are still valid in this embodiment, and will not be repeated here to reduce repetition. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the first or second embodiment.

[0094] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications based on the above-disclosed technical content without departing from the scope of the technical solution of the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
