tft lcd driver ic quotation

Similarly, Tft LCD drivers provide smooth and easy to maintain components with a higher charging voltage. In other words, Tft LCD driver provide an easy-to-use option and consume quite some energy on the components, while Tft lcd driver offer a more convenient option and consume less energy to maintain.

Similarly, Tft lCD drivers are much larger in the compared of Tft LCD ones and more important are the differences between Tft LCD and Tft LCD drivers. However, the biggest difference in their functions include that, it can be more into the sizes of Tft LCD drivers.

There are other types of Tft lCD driver, such as amber tft stick driver, battery tft lcd driver, and strip sticks for battery tft drivers. In this type, the sticks are free of the battery and can be used into many other if as is the case. Moreover, the tft lcd driver vary in its aspects as it is powered and can be used with many others.

There are two types of Tft lCD driver for 12v and one such is the Tft LCD driver 12v. In this case, the Tft LCD driver for 12v is also called the Tft LCD driver from 12v to 24v. It is essential to know that a tft lCD driver is 12v or 24v. and in this case, a tft lcd driver with 12v power supply can be obtained.

Quote: This display uses the NT57860 driver IC. I"m using the TC358860 eDP-to-MIPIDSI bridge chip, but I"m not sure whether it can drive this display panel. Is it possible to share the datasheet of this NT57860 driver IC? That way I"m able to verify that. Thanks in advance, With kind regards

Since the reference voltages are connected to all channels, many DACs may use the same reference voltage. The more DACs there are connected to a single reference voltage, the larger the required C-DAC settling time. This study simulates the settling time for different numbers of connected DACs using a 0.35-μm 5-V CMOS model. Figure 11 shows the simulated results where the settling time is measured at 99.9% of its final voltage for a full swing (0.266 V ~ 4.75 V). The settling time is 5.2 μs when 200 DACs are connected to a single reference voltage. Although a column driver IC contains several hundreds or even up to a thousand DACs, these DACs are distributed to 256 (28) reference voltages. This means that not all the DACs are connected to a single reference voltage. A typical UXGA (1600×1200) display has a pixel clock frequency of 162 MHz and a horizontal scanning time of 9.877 μs [4]. Hence, the proposed column driver is suitable for UXGA displays.

Due to the limited silicon area, the proposed LCD column driver has only four channels. The 10-bit LCD column driver with R-DAC and C-DAC was fabricated using a 0.35-μm 5-V CMOS technology. Table I shows the device sizes used in the proposed column driver, where Rtop, Rmid, Rbot, and Ri are designated in Figure 7. Figure 12 is a photograph of the die. Except for the resistor string of the R-DAC, the die area is 0.2×1.26 mm2 for four channels. Each RGB digital input code is 10-bits wide.

The Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are typically measured for a DAC. However, it is difficult to determine these two specifications for a nonlinear DAC. To demonstrate the performance of the proposed circuit, the nonlinear gamma voltages are not applied to the R-string and the resistor values of the resistor string are made equal. Since an LCD panel needs several column drivers, the uniformity of different drivers is very important. Figure 13 shows the measured transfer curves of a DAC for eight off-chip column drivers. To show the deviation between different chips, Figure 14 provides an

enlarged view of the transfer curves, where the maximum deviation is 3.5 mV from the mean. This deviation is mainly due to process variations. The approach in this study uses no error correction. Hence, the deviation can be reduced by applying an offset canceling technique to the buffer amplifier. Figures 15(a) and (b) show the DNL values for positive and negative polarities, respectively. Figures 16(a) and (b) show the INL values for positive and negative polarities, respectively. The combination of R-DACs and C-DACs creates two groups of DNL values. The maximum DNL and INL values are 3.83 and 3.84 LSB, respectively. This study uses a 1-LSB voltage of 2.44mV to calculate the INL and DNL values. The linearity, however, is less important than the deviations between off-chip drivers for LCD drivers [2].

Figure 17 shows the measured output waveforms of two neighboring channels under dot inversion for the RGB digital inputs of ‘1111111111.’ Here, the voltage levels for negative and positive polarities are 0.266 V and 4.75 V, respectively. A load resistor of 5 kΩ and a capacitor of 90 pF were used. Figure 18 shows a similar waveform for ‘0000000000’ inputs, where the corresponding voltage levels for negative and positive polarities are 2.425 V and 2.598 V, respectively. These two figures show that the settling time is within 3 μs, which is smaller than that of previously published work [2] and standard UXGA displays [5]. Table II summarizes the performance of the proposed column driver IC. The average area per channel is 0.063 mm2, which is smaller than the reported areas of fully R-DAC-based column drivers [5, 8]. These experimental results show that the proposed column driver is suitable for UXGA LCD-TV applications.

Abstract:A two-stage driving circuit of a one-chip TFT-LCD driver IC for portable electronic devices is proposed.The driving buffers of the new circuit are built in the γ-correction circuit rather than in the source driver.The power consumption,die area,and driving capability of the driving circuit are discussed in detail.For a two-stage driving circuit with 13 driving buffers,the settling time of the driving voltage within 0.2% error is about 19.2μs when 396 pixel-loads are driven by the same grayscale voltage.The quiescent current of the whole driving circuit is 518μA,and the power consumption can be reduced by 77%.The proposed driving circuit is successfully applied in a 132RGB×176-dot,260k color one-chip driver IC developed by us for the TFT-LCD of mobile phone,and it can also be used in other portable electronic devices, such as PDAs and digital cameras.
