 Background Art In recent years, portable electronic devices using liquid crystal displays, such as electronic notebooks and mobile phones, have become popular. In addition, portable electronic devices up to now only display still images, but portable electronic devices capable of displaying moving images are becoming widespread.

On the other hand, in such portable electronic devices, the display of pictograms indicating the state of exhaustion or alarm of the battery serving as a driving source, in particular, the antenna level, is indispensable. Recently, in order to reduce the cost and space of portable electronic devices, a moving image display area for displaying a main image such as a moving image in a liquid crystal display device, and a pictogram display for displaying a still image such as a pictogram Portable electronic devices that have a realm are emerging.

For example, in a simple matrix type liquid crystal display device, Japanese Patent Laid-Open No. 61-177487 discloses connecting a part of an output terminal of a data side integrated circuit to a pictograph electrode in a pictogram display area. In Japanese Patent Laid-Open No. 2000-10530, a part of the output terminal of the data side integrated circuit is connected to the pictogram electrode in the pictogram display area and the counter electrode formed on the opposing substrate, and the potential difference between the pictogram electrode and the counter electrode is A technique for blinking a pictograph electrode is disclosed. A TFT type liquid crystal display device is described in Japanese Patent Laid-Open No. 2001-183998.

As a result, a segment driver must be provided separately from the drain driver, and there is a problem that it is insufficient in terms of space saving and low cost of the portable electronic terminal.

In addition, the invention described in Japanese Patent Application Laid-Open No. 2001-183998 or 2001-184000 does not disclose a specific input signal and output signal to a data side integrated circuit, but the power supply potential and the data output signal potential of the common electrode. Neither is the relationship disclosed. Further, nothing has been pointed out about the problem of direct current driving resulting from the relationship between the power supply potential of the common electrode and the potential of the data output signal, and there is no disclosure about driving to alleviate the problem.

Accordingly, the present invention provides a liquid crystal display device using a TFT, wherein the liquid crystal display device includes two display areas: an area for displaying an unfixed image and an area for displaying a still image. An object of the present invention is to provide a liquid crystal display device capable of driving both of an unfixed image and a still fixed image by a single drive driver using a driver.

The data lines connected to the thin film transistors arranged in the The terminator integrated circuit is provided with more output terminals than the number of data lines, and the segment electrode is connected to the surplus output terminals of the data side integrated circuit so that the difference between the potential of the common electrode and the potential of the output signal from the data side integrated circuit is obtained. It is characterized by displaying the glyph in the glyph display area.

In the first invention, the output signal from the data side integrated circuit to the segment electrode can be set to different output potentials every predetermined period. In this case, it is possible to suppress the direct current component caused by the difference between the potential of the data output signal and the potential of the common electrode by setting the output potential that is different every predetermined period within the voltage range of the potential of the common electrode. The predetermined period may be a polarity inversion period of the potential of the common electrode, and it is also possible to control different output potentials every predetermined period by an input signal that defines gradation to the data side integrated circuit. .

A liquid crystal display device according to a second invention which achieves the above object is a liquid crystal display device having a moving picture display area for displaying a moving picture and a glyph display area, wherein the moving picture display area is driven by a moving image thin film transistor element. In a liquid crystal display device comprising a display electrode arranged in a matrix and a pictogram display region in which a pictogram electrode driven by a pictograph thin film transistor element is arranged in a predetermined pictogram type, a common electrode is displayed on a moving image.

In this case, when the pictograph electrode of the pictogram display area is composed of segment electrodes as in the first invention, the pictogram is displayed when the phase of the pictogram potential waveform applied to the segment electrode and the common power waveform applied to the common electrode are different. If the phases are the same, the pictograms are not displayed. However, since the power supply potential on the common electrode is driven by correcting and driving a TFT element having an asymmetric electrical characteristic, it becomes a voltage range (low offset potential) having a low potential with respect to the output voltage range of the data side integrated circuit. Therefore, depending on the extent, it is also necessary to control the output potential of the data side integrated circuit by the data gradation input signal in order to suppress the generation of the DC component. On the other hand, in the case where the glyph electrode is driven by the thin film transistor as in the second invention, the glyph is displayed by the difference between the potential of the drain terminal of the thin film transistor and the potential applied to the common electrode. In this case, since the pictograph electrode is also driven by the thin film transistor, control for suppressing the generation of the DC component as in the first invention is unnecessary.

That is, in the above-described configuration of the fourth aspect, the gate terminal of the first glyph TFT 51 and the gate terminal of the second glyph TFT 52 are connected to the other electrodes of the scanning side integrated circuit 27. You are connected. Other configurations of the liquid crystal display device 1115 are the same as those of the liquid crystal display device 15 (see FIG. 2) in the first to third aspects described above, and therefore the liquid crystal display device 15 shown in FIG. The same configuration is attached | subjected with the same code | symbol, and the overlapping description is abbreviate | omitted.

Only the configuration different from the fourth embodiment will be described below. The gate terminal of the first glyph TFT 51 is not particularly limited to any one of the 120 scanning lines 7 connected to the scanning side integrated circuit 27.

The gate terminal of the second glyph TFT 52 has a scan line 7 different from the scan line 7 to which the gate terminal of the first glyph TFT 51 is connected, for example, L (the present embodiment). In this embodiment, L is connected to the scan line 7 on the integer) line 2 to 120 together with the gate terminals of the 237 TFTs 29 arranged on the L line of the moving image display area 34.

Next, the operation of the liquid crystal display device 1115 having the above-described configuration will be described according to the timing chart shown in FIG. In the liquid crystal display device 1115 of the fifth aspect, the background electrode is not provided in the pictogram display region 33. FIG. 13 is a timing chart showing input / output timing for explaining lighting of the pictograph of the data side integrated circuit 26. As shown in FIG.

As shown in Fig. 13, data for displaying the first row is input to the data side integrated circuit 26 immediately before the syringes in the first row. The data of the 239th column is input into the data side integrated circuit 26 at the time t10 of the period in which the data for displaying this 1st line is input, and the data of the 240th column is input to the data side integrated circuit at the time t11.

Although not particularly limited, in the example shown in FIG. 13, the data of the 239th column input at time t10 is "0000".

The output signal reflecting the data for displaying the first row read up to the time t11 is continuously output from the time t12 which is between the first rows of syringes to the time T6. In the period from the time t12 to the time T6, the 237 TFTs and the first pictograph TFT 51 of the moving picture display area 34 connected to the first scanning line 7 are turned on. Therefore, an output signal reflecting the data read at time t10 is supplied to the first pictogram electrode 23, and the blinking of the first pictogram 21 is controlled. On the other hand, in the period from the time t12 to the time T6, since the second pictograph TFT 52 is in an off state, the display data is not supplied to the second pictogram electrode 24. That is, the 240th column data read at the time t11 does not contribute to the display control of the second pictogram 22. Therefore, the data of the 240th column to be read together with the data for displaying the first row may not be constant.

In the period from the time t12 to the time T6, the output signal reflecting the data for displaying the first row is output from the data side integrated circuit 26, and the data for displaying the second row is stored in the data side integrated circuit ( 26). At the time T1, the data of the first column of the second row is input to the data side integrated circuit 26.

Data is input to the data side integrated circuit 26. That is, data for displaying the second row of the moving picture display area 34 from the time T1 to the time T2 is input to the data side integrated circuit 26. At the time T3, the time T4, and the time T5, data of the 238th, 239th and 240th columns are input to the data side integrated circuit 26, respectively.

The output signal reflecting the data for displaying the second row read at the time T2, the time T3, the time T4, and the time T5 from the time T1 between the syringes of the first row is the second row. It outputs continuously from the time t12 of time between syringes (it arranges between 1st-[L-2] lines between syringes) to the time T6. However, in the period from the time t12 to the time T6 between the second row syringes, the 237 TFTs of the moving picture display area 34 connected to the scanning line 7 on the second row are turned on. The first glyph TFT 51 and the second glyph TFT 52 are in an off state. Therefore, the display data is not supplied to the first pictogram electrode 23 and the second pictogram electrode 24 between the syringes in the second row. That is, the 239th column data and the 240th column data read out at the time T4 and time T5 between the 1st line syringes, the display control of the 1st pictogram 21 and the 2nd pictogram 22 is performed. Does not contribute to. This also applies to data for displaying the third to subsequent [L-1] lines. Therefore, between the 239th column data and the 240th column data that is read together with the data for displaying the second to subsequent [L-1] rows, that is, the interval between the syringes in the first row to the syringes in the [L-2] rows. It is not necessary to make the data of the 239th column and the data of the 240th column constant.

The interval between the syringes of the third row to the syringes of the [L-2] rows is the same as the time from the time t12 to the time T6 between the syringes of the second row. The output signal reflecting the data for displaying the [L-1] -th line read at the time T5 from the time T1 between the syringes of the [L-2] -th line is the time between the syringes of the [L-1] -th line. It outputs continuously from T6 to time T12.

In the period from the time T6 to the time t12, the output signal reflecting the data for displaying the [L-1] -th row is output from the data side integrated circuit 26, and the data for displaying the L-th row is data. It is input to the side integrated circuit 26. At time T7, the data of the first column of the L-th row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, data after the second column of the L-th row is input to the data side integrated circuit 26, and the 237th column of the L-th row at time T8 (omitted in FIG. 13). Data is input to the data side integrated circuit 26. That is, data for displaying the L-th row of the video display area 34 from the time T7 to the time T8 is input to the data side integrated circuit 26. At the time T9, the time T10, and the time t11, data of the 238th, 239th and 240th columns are input to the data side integrated circuit 26, respectively. Data relating to the blinking of the second pictogram 22 is defined by the data input at time T11. Although not particularly limited, in the example shown in FIG. 13, the 240th column data input at the time T11 is "1111".

The output signal reflecting the data for displaying the L-th row read at the time T11 from the time T7 is continuously output from the time T12 between the L-th syringes to the time T18. In the period from the time T12 to the time T18, the 237 TFTs and the second pictograph TFTs 52 of the moving picture display area 34 connected to the L-th scan line 7 are turned on. Therefore, the output signal reflecting the data read at the time T11 between the syringes of the [L-1] lines is supplied to the second pictograph electrode 24, and the blinking of the second pictogram 22 is controlled. On the other hand, in the period from the time T12 to the time T18, since the first pictograph TFT 51 is in an off state, the display data is not supplied to the first pictogram electrode 23. That is, the 239th column data read at the time T10 between the syringes of the [L-1] lines does not contribute to the display control of the first pictogram 21. Therefore, the data of the 239th column to be read together with the data for displaying the Lth line between the syringes of the [L-1] -th row may not be made constant.

The interval between the syringes in the L-th row is the same as the time from the time t12 between the syringes in the second row to the time T6. Therefore, the data of the 239th column and the 240th column data read after the L-th syringe | interval may not be made constant.

That is, when the data of the 239th column and the 240th column are summarized, the data for displaying the 1st line of the moving image display area 34, i.e., the data to be read immediately before the 1st line of the syringe, for the 239th column data, Except that, it may not be constant. The data of the 240th column may not be constant except for data for displaying the Lth row of the moving image display area 34, that is, data read between the syringes of the [L-1] th row.

The second pictograph electrode 24 for driving by the character TFT 53 and for displaying the second pictogram is formed by the second pictogram TFT 52 and the fourth pictogram TFT 54. As a configuration for driving, the first pictograph TFT 51 and the third pictogram TFT 53 are turned on at different timings, and the second pictogram TFT 52 and the fourth pictogram TFT are turned on. 54 is set to the on state at different timings. That is, in the sixth aspect, the gate terminal of the first glyph TFT 51 and the gate terminal of the third glyph TFT 53 are connected to other electrodes of the scanning side integrated circuit 27. The gate terminal of the second glyph TFT 52 and the gate terminal of the fourth glyph TFT 54 are connected to other electrodes of the scanning side integrated circuit 27. The other configuration of the liquid crystal display device 1315 is the same as that of the liquid crystal display device 15 (see FIG. 2) in the first to third aspects described above, and therefore the same as that of the liquid crystal display device 15 shown in FIG. The same code | symbol is attached | subjected about a structure and the overlapping description is abbreviate | omitted.

Only the configuration different from the sixth embodiment will be described below. The source terminal of the third glyph TFT 53 is connected to the signal line 19 to which the source terminal of the first glyph TFT 51 is connected. The drain terminal of the third glyph TFT 53 is connected to the first glyph electrode 23. The gate terminal of the third glyph TFT 53 is different from the scan line 7 of the first row to which the gate terminal of the first glyph TFT 51 is connected, for example, K ( In this embodiment, K is connected to the scan line of the integer) 2nd -120th line. Gate lines of the 237 TFTs 29 arranged in the K-th row of the moving image display area 34 are also connected to the K-th scan line 7.

The source terminal of the fourth glyph TFT 54 is connected to the signal line 20 to which the source terminal of the second glyph TFT 52 is connected. The drain terminal of the fourth glyph TFT 54 is connected to the second glyph electrode 24. The gate terminal of the fourth glyph TFT 54 is different from the L line scan line 7 to which the gate terminal of the third glyph TFT 53 is connected, for example, M ( In the present embodiment, M is connected to the scan line on the integer) line of 2 to 120. Gate lines of the 237 TFTs 29 arranged in the M-th row of the moving image display area 34 are also connected to the M-th scan line 7.

Next, the operation of the liquid crystal display device 1315 having the above-described configuration will be described according to the timing charts shown in FIGS. 16 and 17. The liquid crystal display 1315 of the seventh form is such that the background electrode is not provided in the pictogram display region 33. 16 and 17 are timing charts showing input and output timings for explaining lighting of pictograms of the data-side integrated circuit 26.

As shown in Fig. 16, data for displaying the first row is input to the data side integrated circuit 26 immediately before the first row of syringes. The data of the 239th column is input into the data side integrated circuit 26 at the time t10 of the period in which the data for displaying this 1st line is input, and the data of the 240th column is input to the data side integrated circuit at the time t11. It is input to (26). In other words, data relating to the blinking of the first pictogram 21 at time t10 is defined. Although not particularly limited, in the example shown in FIG. 16, the data of the 239th column input at time t10 is "0000".

The output signal reflecting the data for displaying the first row read up to the time t11 is continuously output from the time t12 which is between the first rows of syringes to the time T6. In the period from the time t12 to the time T6, the 237 TFTs and the first pictograph TFT 51 of the moving picture display area 34 connected to the scanning line 7 of the first row are turned on. Therefore, an output signal reflecting the data read at time t10 is supplied to the first pictogram electrode 23, and the blinking of the first pictogram 21 is controlled. On the other hand, since the second pictograph TFT 52 is in the off state in the period from the time t12 to the time T6, the display data is not supplied to the second pictogram electrode 24. That is, the 240th column data read at the time t11 does not contribute to the display control of the second pictogram 22. Therefore, the data of the 240th column to be read together with the data for displaying the first row may not be constant.

In the period from the time t12 to the time T6, the output signal reflecting the data for displaying the first row is output from the data side integrated circuit 26, and the data for displaying the second row is stored in the data side integrated circuit ( 26). At the time T1, the data of the first column of the second row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, data after the second column of the second row is input to the data side integrated circuit 26, and the 237th column of the second row at time T2 (omitted in FIG. 16). Data is input to the data side integrated circuit 26. That is, data for displaying the second row of the moving picture display area 34 from the time T1 to the time T2 is input to the data side integrated circuit 26. At the time T3, the time T4, and the time T5, data of the 238th, 239th and 240th columns are input to the data side integrated circuit 26, respectively.

The output signal reflecting the data for displaying the second row read at the time T2, the time T3, the time T4, and the time T5 from the time T1 between the syringes of the first row is the second row. It is output continuously from the time t12 of time between syringes (it arranges between the syringes of the 1st-[K-2] -th row in FIG. 16) to the time T6. However, the time (t12) between the 2nd syringes ) 237 TFTs in the moving picture display area 34 connected to the second scanning line 7 are turned on in the period from time to time T6, but the first pictogram TFT 51 and the second picture are turned on. The character TFT 52 is in the off state, so that the display data is not supplied to the first pictograph electrode 23 and the second pictogram electrode 24 between the second row syringes. The data of the 239th row and the 240th column read at the time T4 and the time T5 between syringes are the same as that of the 1st pictogram 21 and the 2nd pictogram 22. This does not contribute to the display control, which is the same for the data for displaying from the third row to the [K-1] line, and therefore the 239th column read together with the data for displaying the second to subsequent [K-1] lines. The data of the 239th column and the 240th column of data which are read between the data of the second column and the data of the 240th column, that is, between the syringes of the first row to the between the syringes of the [K-2] row may not be constant.

The interval between the syringes of the third row and the syringes of the [K-2] rows is the same from the time t12 to the time T6 between the syringes of the second row. The output signal reflecting the data for displaying the [K-1] rows read at the time T5 from the time T1 between the syringes in the [K-2] rows is the time between the syringes in the [K-1] rows. It outputs continuously from T6 to time T12.

In the period from the time T6 to the time T12, an output signal reflecting the data for displaying the [K-1] -th row is output from the data side integrated circuit 26, and data for displaying the K-th row is data. It is input to the side integrated circuit 26. At time T7, the data of the first column of the K-th row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, the data after the second row of the K-th row is input to the data side integrated circuit 26, and the 237th column of the K-th row at time T8 (omitted in FIG. 16). Data is input to the data side integrated circuit 26. That is, data for displaying the K-th row of the moving image display area 34 from the time T7 to the time T8 is input to the data side integrated circuit 26. At the time T9, the time T10, and the time T11, data of the 238th column, the 239th column, and the 240th column are input to the data side integrated circuit 26, respectively. Data relating to the blinking of the first pictogram 21 is defined by the data input at time T10. Although not specifically limited, in the example shown in FIG. 16, the data of the 239th column input at the time T10 is "0000".

The output signal reflecting the data for displaying the K-th row read at the time T11 from the time T7 is continuously output from the time T12 between the K-th syringes to the time T18. In the period from the time T12 between the K-th syringes to the time T18, 237 TFTs of the moving picture display area 34 connected to the K-th scanning line 7 and the first pictograph TFT 51 Is on. Therefore, the output signal reflecting the data read at the time T10 between the syringes of the [K-1] lines is supplied to the first pictograph electrode 23, and the blinking of the first pictogram 21 is controlled. On the other hand, since the second pictograph TFT 52 is in the off state in the period from the time T12 to the time T18 between the K-th syringes, the display data is supplied to the second pictogram electrode 24. It doesn't work. In other words, the 240th column data read at the time T11 between the syringes of the [K-1] lines does not contribute to the display control of the second pictogram 22. Therefore, the data of the 240th column to be read together with the data for displaying the Kth line between the syringes of the [K-1] -th row may not be made constant.

In the period from the time T12 to the time T18, the output signal reflecting the data for displaying the K-th row is output from the data side integrated circuit 26, and the data for displaying the [K + 1] -th row is data. It is input to the side integrated circuit 26. At time T13, data of the first column of the [K + 1] -th row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, data after the second column of the [K + 1] -th row is input to the data side integrated circuit 26, and [K] is omitted at time T14 (omitted in FIG. 16). Data of the 237th column of the +1] th line is input to the data side integrated circuit 26. As shown in FIG. That is, data for displaying the [K + 1] th line of the moving image display area 34 from the time T13 to the time T14 is input to the data side integrated circuit 26. At the time T15, the time T16, and the time T17, data of the 238th, 239th and 240th columns are input to the data side integrated circuit 26, respectively.

The output signal reflecting the data for displaying the [K + 1] -th row read at the time T17 from the time T13 between the K-th syringe-injectors is the interval between the syringes of the [K + 1] -th row (K-1 in FIG. 16). The output is continued from the time T12 of the [L-2] -th row syringes to the time T18. However, between the syringes in the [K + 1] rows, the 237 TFTs in the moving image display area 34 connected to the scanning line 7 in the [K + 1] rows are turned on, but the TFT for the first glyph ( 51 and the second pictograph TFT 52 are in an off state. Therefore, the display data is not supplied to the first pictograph electrode 23 and the second pictogram electrode 24 between the syringes in the [K + 1] -th row. That is, the 239th column data and the 240th column data read at the time T16 and the time t17 between the K-th syringes are controlled by the display control of the first pictogram 21 and the second pictogram 22. Does not contribute. The same applies to the data for displaying the [L-1] th row after this. Therefore, the data of the 239th column and the 240th column of data read together with the data for displaying the [K + 1] th to the [L-1] th rows, that is, between the syringes of the Kth row and the [L-2] th rows The data of the 239th column and the 240th column which are read in the meantime may not be constant.

The time interval between the syringes in the [K + 2] rows and the syringes in the [L-2] rows is the same as the time (T12) to the time T18 between the syringes in the [K + 1] rows. The output signal reflecting the data for displaying the [L-1] th line read at the time T17 from the time T13 between the syringes of the [L-2] th line is shown in the [L-1] th line shown in FIG. It outputs continuously from time T18 between syringes to time T24.

In the period from the time T18 to the time T24, an output signal reflecting the data for displaying the [L-1] -th row is output from the data side integrated circuit 26, and data for displaying the L-th row is data. It is input to the side integrated circuit 26. At time T19, the data of the first column of the L-row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, data after the second row of the L-th row is input to the data side integrated circuit 26, and at the time T20 (omitted in FIG. 17), the 237th column of the L-th row is performed. Data is input to the data side integrated circuit 26. That is, data for displaying the L-th row of the moving image display area 34 from the time T19 to the time T20 is input to the data side integrated circuit 26. At the time T21, the time T22, and the time T23, data of the 238th column, the 239th column, and the 240th column are input to the data side integrated circuit 26, respectively. Data relating to the blinking of the second pictogram 22 is defined by the data input at time T23. Although not particularly limited, in the example shown in FIG. 17, the 240th data input at the time T23 is "1111".

The output signal reflecting the data for displaying the L-th row read at the time T23 from the time T19 is continuously output from the time T24 between the L-th syringes to the time T30. In the period from the time T24 between the L-th syringes to the time T30, 237 TFTs and the second pictograph TFT 52 of the moving image display area 34 connected to the L-th scanning line 7 are provided. Is on. Therefore, an output signal reflecting the data read at the time T23 between the syringes in the [L-1] lines is supplied to the second pictograph electrode 24, and the blinking of the second pictogram 22 is controlled. On the other hand, since the first pictograph TFT 51 is in the off state in the period from the time T24 between the L-th syringes to the time T30, the display data is supplied to the first pictogram electrode 23. It doesn't work. That is, the 239th column data read at the time T22 between the syringes of the [L-1] lines does not contribute to the display control of the first pictogram 21. Therefore, the data of the 239th column to be read together with the data for displaying the Lth line between the syringes of the [L-1] -th row may not be made constant.

In the period from the time T24 between the L row syringes to the time T30, an output signal reflecting data for displaying the L row is output from the data side integrated circuit 26 and the [L + 1] row is Data for display is input to the data side integrated circuit 26. At the time T25 between the syringes of the L-th row, the data of the first column of the [L + 1] -th row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, data after the second column of the [L + 1] -th row is input to the data side integrated circuit 26, and [L] is omitted at time T26 (omitted in FIG. 17). Data of the 237th column of the +1] th line is input to the data side integrated circuit 26. As shown in FIG. That is, data for displaying the [L + 1] th line of the moving image display area 34 from the time T25 to the time T26 is input to the data side integrated circuit 26. At the time T27, the time T28, and the time T29, data of the 238th column, the 239th column, and the 240th column are input to the data side integrated circuit 26, respectively.

The output signal reflecting the data for indicating the [L + 1] th line read at the time T29 from the time T25 between the Lth syringes is the interval between the syringes of the [L + 1] th line (L in FIG. 17). It is output continuously from the time T24 of the ... [M-2] line to the syringe) to the time T30. However, between the syringes in the [L + 1] rows, the 237 TFTs in the moving image display area 34 connected to the scanning line 7 in the [L + 1] rows are turned on, but the first pictograph TFT ( 51 and the glyph TFT 52 are in an off state. Therefore, the display data is not supplied to the first pictograph electrode 23 and the second pictogram electrode 24 between the syringes in the [L + 1] -th row. That is, the data of 239 columns and 240 columns read at the time T28 and the time T29 between the L-th syringes contribute to the display control of the first pictogram 21 and the second pictogram 22. I never do that. The same applies to data for displaying the [M-1] th line after this. Therefore, the data of the 239th column and the 240th column of data read together with the data for displaying the [L + 1] th to the [M-1] th rows, that is, between the Lth syringe and the [M-2] th syringe The data of the 239th column and the 240th column which are read in the meantime may not be constant.

The interval between the syringes in the [L + 2] rows and the syringes in the [M-2] rows is the same as the time (T24) to the time (T30) between the syringes in the [L + 1] rows. The output signal reflecting the data for displaying the [M-1] rows read at the time T29 from the time T25 between the syringes of the [M-2] rows is the interval between the syringes of the [M-1] rows. The output continues from the time T30 to the time 36.

In the period from the time T30 to the time T36, an output signal reflecting the data for displaying the [M-1] -th row is output from the data side integrated circuit 26, and data for displaying the M-th row is data. It is input to the side integrated circuit 26. At time T31, the data of the first column of the M-th row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, data after the second column of the M-th row is input to the data side integrated circuit 26, and at the time 32 (omitted in FIG. 17), the 237th column of the M-th row is obtained. Data is input to the data side integrated circuit 26. That is, data for displaying the M-th line of the moving image display area 34 from the time T31 to the time T32 is input to the data side integrated circuit 26. At the time T33, the time T34, and the time T35, data of the 238th, 239th and 240th columns are input to the data side integrated circuit 26, respectively. Data relating to the blinking of the second pictogram 22 is defined by the data input at time T35. Although not particularly limited, in the example shown in FIG. 17, the 240th data input at the time T35 is "1111".

The output signal reflecting the data for displaying the M-th row read at the time T35 from the time T31 is output after the time T36 between the M-th syringes. Between the M rows of syringes, the 237 TFTs and the second pictograph TFTs 52 of the moving image display area 34 connected to the M lines of the scanning lines 7 are turned on. Therefore, the output signal reflecting the data read at the time T35 between the syringes of the [M-1] lines is supplied to the second pictograph electrode 24, and the blinking of the second pictogram 22 is controlled. On the other hand, since the first pictograph TFT 51 is in the off state between the M-th syringes, the display data is not supplied to the first pictogram electrode 23. That is, the 239th column data read at the time T34 between the syringes of the [M-1] lines does not contribute to the display control of the first pictogram 21. Therefore, the data of the 239th column to be read together with the data for displaying the Mth line between the syringes of the [M-1] rows may not be constant.

The interval between the syringes in the M-row is the same as the time between the syringes in the [L + 1] -th row from the time T24 to the time T30. Therefore, the data of the 239th column and the 240th column which are read after the interval between the Mth syringes may not be made constant.

That is, when the data of the 239th column and the 240th column are summarized, the data for displaying the 1st row and the Kth row of the moving image display area 34, i.e., the data of the 239th column, are immediately read between the syringes of the first row. The data may not be constant except for the data to be read and the data to be read between the [K-1] -th syringes. In the 240th column, data for displaying the L and M rows of the moving image display area 34, that is, the data read between the syringes in the [L-1] rows and the syringe in the [M-1] rows, is displayed. Except for the data to be read, it may not be constant.

As shown in FIG. In the description of this timing chart, N is an integer of 120 or more. In the present embodiment, the moving image display area 34 does not exist after the 121st row, but for convenience of description, the scanning side integrated circuit in which the gate terminal of the second pictograph TFT 52 is connected via the scanning line 55. The surplus terminal 56 in (27) is called the terminal of the [N + 1] th line.

As shown in Fig. 19, data for displaying the first row is input to the data side integrated circuit 26 immediately before the syringes in the first row. The data of the 239th column is input into the data side integrated circuit 26 at the time t10 of the period in which the data for displaying this 1st line is input, and the data of the 240th column is input to the data side integrated circuit at the time t11. It is input to (26). In other words, data concerning the blinking of the first pictogram 21 at time t10 is defined. Although not particularly limited, in the example shown in FIG. 19, the data of the 239th column input at time t10 is "0000".

The output signal reflecting the data for displaying the first row read up to the time t11 is continuously output from the time t12 which is between the first rows of syringes to the time T6. In the period from the time t12 to the time T6, the 237 TFTs and the first pictograph TFT 51 of the moving picture display area 34 connected to the scanning line 7 of the first row are turned on. Therefore, an output signal reflecting the data read at time t10 is supplied to the first pictogram electrode 23, and the blinking of the first pictogram 21 is controlled. On the other hand, since the second pictograph TFT 52 is in the off state in the period from the time t12 to the time T6, the display data is not supplied to the second pictogram electrode 24. That is, the 240th column data read at the time t11 does not contribute to the display control of the second pictogram 22. Therefore, the data of the 240th column to be read together with the data for displaying the first row may not be constant.

In the period from the time T12 between the first syringes to the time T6, an output signal reflecting the data for displaying the first row is output from the data side integrated circuit 26 and data for displaying the second row. Is input to the data side integrated circuit 26. At the time T1, the data of the first column of the second row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, data after the second column of the second row is input to the data side integrated circuit 26, and the 237th column of the second row at time T2 (omitted in FIG. 19). Data is input to the data side integrated circuit 26. That is, data for displaying the second row of the moving picture display area 34 from the time T1 to the time T2 is input to the data side integrated circuit 26. At the time T3, the time T4, and the time T5, data of the 238th, 239th and 240th columns are input to the data side integrated circuit 26, respectively.

The output signal reflecting the data for displaying the second row read at the time T2, the time T3, the time T4, and the time T5 from the time T1 between the syringes of the first row is the second row. It outputs continuously from time t12 to time T6 between syringes (it arranges between the syringes of the 1st-[N-1] -th rows in FIG. 19). However, in the period from the time t12 to the time T6 between the syringes in the second row, 237 TFTs in the moving image display area 34 connected to the scan line 7 in the second row are turned on. The first glyph TFT 51 and the second glyph TFT 52 are in an off state. Therefore, the display data is not supplied to the first pictogram electrode 23 and the second pictogram electrode 24 between the syringes in the second row. That is, the 239th column data and the 240th column data read out at the time T4 and time T5 between the 1st line syringes, the display control of the 1st pictogram 21 and the 2nd pictogram 22 is performed. Does not contribute to. The same applies to the data for displaying the third to the Nth rows. Therefore, the data of the 239th column and the 240th column of data read together with the data for displaying the 2nd to the Nth row, that is, the 239th column read between the syringes of the 1st line and the syringes of the [N-1] th line. And the data in column 240 may not be constant.

The interval between the syringes of the third row and the syringes of the [N-1] -th row is the same as that from the time t12 to the time T6 between the 2nd-row syringes. The output signal reflecting the data for displaying the N-th row read in the time T5 from the time T1 between the syringes of the [N-1] -th row is the time-T12 from the time T6 between the N-th syringes. Continue to print.

In the period from the time T6 to the time T12, the output signal reflecting the data for displaying the Nth row is output from the data side integrated circuit 26, and the data for displaying the [N + 1] th row is data. It is input to the side integrated circuit 26. At time T7, the data of the first column of the [N + 1] -th row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, data after the second column of the [N + 1] -th row is input to the data side integrated circuit 26, and [N is omitted at time T8 (Fig. 19). Data of the 237th column of the +1] th line is input to the data side integrated circuit 26. As shown in FIG. That is, data for displaying the [N + 1] th line of the moving image display area 34 from the time T7 to the time T8 is input to the data side integrated circuit 26. At the time T9, the time T10, and the time T11, data of the 238th column, the 239th column, and the 240th column are input to the data side integrated circuit 26, respectively. Data relating to the blinking of the second pictogram 22 is defined by the data input at time T11. Although it does not specifically limit, In the example shown in FIG. 19, the 240th data input at the time T11 is "1111."

The output signal reflecting the data for displaying the [N + 1] -th row read at the time T11 from the time T7 is from the time T12 which is between the syringes of the [N + 1] -th time to the time T18. The output continues. In the period from the time T12 to the time T18, 237 TFTs and the second pictogram TFT 52 of the moving picture display area 34 connected to the scanning line 7 of the [N + 1] -th line are turned on. It becomes a state. Therefore, the output signal reflecting the data read at the time T11 between the Nth syringes is supplied to the second pictograph electrode 24, and the blinking of the second pictogram 22 is controlled. On the other hand, in the period from the time T12 to the time T18, since the first pictograph TFT 51 is in an off state, the display data is not supplied to the first pictogram electrode 23. In other words, the 239th column data read at the time T10 between the Nth syringes does not contribute to the display control of the first pictogram 21. Therefore, the data of the 239th column to be read together with the data for displaying the [N + 1] th line between the Nth syringes may not be constant.

The interval between the syringes of the [N + 1] -th row is the same as the time from the time t12 to the time T6 between the 2nd-row syringes. Therefore, the data of the 239th column and the 240th column that are read after the interval between the syringes of the [N + 1] th rows may not be constant.

That is, when the data of the 239th column and the 240th column are summarized, the data for displaying the 1st line of the moving image display area 34, i.e., the data to be read immediately before the 1st line of the syringe, for the 239th column data, Except that, it may not be constant. The data of the 240th column may not be constant except for data for displaying the [N + 1] th row of the moving image display area 34, that is, data read between the Nth syringes.

Further, even when the gate terminal of the first glyph TFT 51 is connected to the surplus terminal 56 to which the gate terminal of the second glyph TFT 52 of the scanning side integrated circuit 27 is connected, The configuration may be such that the gate terminal of the second glyph TFT 52 is connected to a surplus terminal different from the surplus terminal 56 to which it is connected.

The first glyph TFT 51 and the second glyph TFT 52 are in an off state. Therefore, the display data is not supplied to the first pictogram electrode 23 and the second pictogram electrode 24 between the syringes in the second row. That is, the 239th column data read at the time T4 between the syringes of the first row does not contribute to the display control of the first pictogram 21 and the second pictogram 22. This also applies to data for displaying the third to subsequent [L-1] lines. Therefore, the 239th column of data read together with the data for displaying the second to subsequent [L-1] rows, that is, the 239th column read between the syringes in the first row to the syringes in the [L-2] rows. The data may not be constant.

The interval between the syringes of the third row to the syringes of the [L-2] rows is the same as the time from the time t12 to the time T6 between the syringes of the second row. The output signal reflecting the data for displaying the [L-1] -th line read at the time T5 from the time T1 between the syringes of the [L-2] -th line is the time between the syringes of the [L-1] -th line. It outputs continuously from T6 to time T12.

In the period from the time T6 to the time T12, the output signal reflecting the data for displaying the [L-1] -th row is output from the data side integrated circuit 26, and the data for displaying the L-th row is data. It is input to the side integrated circuit 26. At time T7, the data of the first column of the L-th row is input to the data side integrated circuit 26. Hereinafter, in synchronization with the rise of the sequential data signal, data after the second column of the L-th row is input to the data side integrated circuit 26, and at the time T8 (omitted in FIG. 21), the 237th column of the L-th row is obtained. Data is input to the data side integrated circuit 26. That is, data for displaying the L-th row of the video display area 34 from the time T7 to the time T8 is input to the data side integrated circuit 26. At the time T9, the time T10, and the time T11, data of the 238th column, the 239th column, and the 240th column are input to the data side integrated circuit 26, respectively. Data relating to the blinking of the second pictogram 22 is defined by the data input at time T10. Although not particularly limited, in the example shown in FIG. 21, the 239th data input at the time T10 is "1111".

The output signal reflecting the data for displaying the L-th row read at the time T11 from the time T7 is continuously output from the time T12 between the L-th syringes to the time T18. In the period from the time T12 to the time T18, the 237 TFTs and the second pictograph TFTs 52 of the moving picture display area 34 connected to the L-th scan line 7 are turned on. Therefore, the output signal reflecting the data read at the time T10 between the syringes of the [L-1] lines is supplied to the second pictograph electrode 24, and the blinking of the second pictogram 22 is controlled.

The interval between the syringes in the L-th row is the same as the time from the time t12 between the syringes in the second row to the time T6. Therefore, the data of the 239th column read after the L-throw between syringes may not be constant.

Cr metal is used as the dividing line 103 in the aspect of the present invention, but other metals or organic films used for color filters and the like may be used.

As mentioned above, although the nine forms were demonstrated by the pulse height modulation (PHM) means which expresses the gradation by the potential difference, it can be similarly performed by the pulse width modulation (PWM) means which expresses the gradation by the pulse width in either example. In the nine aspects described above, the embodiment of the chip-on-glass mounting method has been described. However, the mounting structure by other methods such as the TAB mounting method can also be used. In addition, although the liquid crystal display device of normally white was demonstrated in the above embodiment, this invention is similarly applicable also to normally black. Of course, the number of pictograms is not limited to two, and does not prescribe which pictogram to light up.

In each of the above embodiments, a data side integrated circuit and a scan side integrated circuit are provided, but an integrated circuit in which these functions are arranged in one chip may be used. Moreover, it can also be set as the structure which combined said 4th-9th aspect suitably.

As is apparent from the above description, according to the present invention, in the TFT type liquid crystal display device which displays a pictogram based on the potential difference between the common power supply and the data output signal of the data side integrated circuit, the data side integrated circuit is connected to the common power supply. By driving in accordance with the polarity, the segment driver for segment display is unnecessary, and low cost can be achieved with space saving. In the second aspect, the DC component in the glyph drive can be reduced by adjusting the gradation of the data output signal. In the third aspect, the boundary between the moving picture display area and the pictogram display area becomes clear, making the moving picture easy to see and hardly affecting the design of the moving picture display area. In the fourth to ninth aspects, the control for suppressing the generation of the direct current component as in the second and third aspects becomes unnecessary. By doing so, the circuit for constructing this becomes unnecessary, and space saving can be expected. Moreover, according to this aspect, driving power can be made low.

In particular, in the fourth to ninth aspects, since the wiring for the glyphs is easy according to the fourth aspect, the wiring space can be reduced. In addition, according to the fifth aspect, wiring for separated pictograms is facilitated, so that wiring space can be reduced. According to the sixth aspect, since the total impedance of the thin film transistor driving the glyph electrode is lowered, it is possible to reliably turn on and off the wide glyph at high speed, and to increase the contrast of the wide glyph. At the same time, if any one of the plurality of thin film transistors connected to one pictogram electrode is normal, the pictogram can be driven, thereby lowering the lighting failure rate of the pictogram. According to the seventh aspect, since the writing of the pictograms to the pixels is performed at different timings, the contrast is improved even when using a liquid crystal with a fast response time, so that the AC driving period can be shortened, thereby preventing deterioration of the liquid crystal. have. According to the eighth aspect, since the thin film transistor for driving the glyph electrode is scanned independently from the thin film transistor in the moving picture display area, the thin film transistor for driving the glyph electrode is driven together with the thin film transistor in the moving picture display area. It is possible to prevent waveform blur caused by the gate capacitance. According to the ninth aspect, the number of output terminals of the data side integrated circuit can display at least a plurality of pictograms.

As described above, the present invention is a liquid crystal display device using a TFT, which is space-saving in a liquid crystal display device having two display areas: an area for displaying an unfixed image and an area for displaying a still image. Moreover, it is suitable for the liquid crystal display device which can drive both an unfixed image and a still fixed image by one drive driver using a low cost driver.
