Description

Temperature-based display drive compensation method, electronic chip, and information processing device

The present invention relates to the field of display driver chips, and more particularly to a temperature-based display driver compensation method implemented by a display driver chip.

Figure 1 is a block diagram of a conventional OLED display. As shown in Figure 1, the conventional OLED display 1a primarily comprises an OLED display panel 11a and at least one display driver chip 12a. The OLED display panel 11a includes a plurality of OLED elements and a plurality of pixel circuits for controlling the light emission of the plurality of OLED elements. During normal operation, the display driver chip 12a receives input display data from a host computer 2a (e.g., an application processor (AP)) and, after performing at least one type of data processing and/or compensation on the input display data, obtains output display data. Ultimately, the OLED display panel 11a is driven by the output display data.

Figure 2 shows a voltage-current density curve for an OLED device. As shown in Figure 2, practical experience shows that the OLED device's luminance (∝current density) increases with increasing temperature at the same drive voltage. In other words, while the display driver chip 12a drives the OLED display panel 11a based on the output display data comprising multiple data voltages (VDATA), changes in ambient temperature can cause variations in the OLED device's luminance. This results in inconsistent brightness in the image displayed by the OLED display panel 11a, preventing it from providing stable display brightness and/or color.

In summary, it is necessary to develop and design a temperature-based display driver compensation solution for integration into the display driver chip 12a, so that the display driver chip 12a can provide corresponding display driver compensation to the OLED display panel 11a based on changes in ambient temperature and changes in the operating temperature of the display driver chip 12a.

From the above description, it can be seen that a temperature-based display drive compensation method is urgently needed in this field.

The primary objective of this invention is to provide a temperature-based display driver compensation method, implemented by a display driver chip containing a temperature compensation unit, to perform temperature-based display driver compensation on an OLED panel.

In order to enable the Review Committee to further understand the structure, features, purpose, and advantages of the present invention, the following are attached with drawings and detailed descriptions of preferred specific embodiments.

First embodiment

FIG. 3 is a block diagram of an OLED display applying a temperature-based display driving compensation method of the present invention. As shown in FIG. 3 , the OLED display 1 includes: a display panel 11 and at least one electronic chip 12 . The OLED display panel 11 includes M×N OLED elements 111 and M×N pixel circuits 112 for controlling the light emission of the OLED elements 111 . M and N are positive integers, and the electronic chip 12 contains a temperature compensation unit 121 . In a feasible embodiment, the electronic chip 12 may be, but is not limited to, a display driver chip or a touch and display driver integration (TDDI) chip.

Furthermore, Figure 4 is a circuit topology diagram of the pixel circuit 112 shown in Figure 3. In a feasible embodiment, the pixel circuit 112 can adopt a circuit structure design such as 3T1C, 4T1C, 5T1C, 6T1C, 7T1C, 8T1C, 7T2C, or 8T2C. For example, the pixel circuit 112 in FIG. 4 includes a first TFT element M1, a second TFT element M2, a third TFT element M3, a fourth TFT element M4, a fifth TFT element M5, a sixth TFT element M6, a seventh TFT element M7, and a storage capacitor Cst, wherein the first TFT element M1 is a switching element that drives the OLED element 111, the second TFT element M2 is a switching element that transmits a data voltage (VDATA), and the fifth TFT element M5 and the sixth TFT element M6 adjust the luminance of the OLED element 111 according to a dimming signal (EM) having a specified duty cycle.

According to the first embodiment of the present invention, the temperature-based display drive compensation method mainly includes the following steps: enabling the temperature compensation unit 121 during a normal display drive period, so that the temperature compensation unit 121 performs a display drive compensation operation according to temperature sensing data.

Electronic engineers familiar with the design and manufacture of display driver chips will understand that after receiving input display data from the host computer 2 (as shown in FIG. 3 ), the electronic chip 12 (e.g., DDIC) typically performs at least one type of data processing (e.g., color gamut conversion) and/or data compensation (e.g., OLED aging compensation) on the input display data to obtain output display data. Finally, the OLED display panel 11 is driven based on the output display data. Therefore, in a feasible embodiment, the temperature compensation unit 121 can be configured to generate compensation data based on temperature sensing data, and use the compensation data to compensate the input display data into output display data, so that the electronic chip 12 drives the OLED display panel 11 according to the output display data to realize the display drive compensation operation.

Specifically, as shown in FIG2 , the measurement data confirms that the changes in the luminance (current density) of each OLED element 111 at different temperatures can be determined. Therefore, the measurement data can be used to pre-create a lookup table (LUT) and configure it within the electronic chip 12. The LUT includes a plurality of temperatures, a plurality of current densities (luminance) corresponding to the plurality of temperatures, and a plurality of grayscale values corresponding to the plurality of temperatures and the plurality of current densities. It should be understood that input display data includes M×N pixel grayscale values corresponding to the M×N OLED elements 111; therefore, when the temperature changes from a first temperature to a second temperature, the temperature compensation unit 121 can look up the M×N grayscale values corresponding to the second temperature and the specified luminous brightness in the lookup table, and then use the M×N grayscale values to compensate the input display data to become the output display data.

Electronic engineers familiar with the design and manufacture of display driver chips also know that gamma correction circuits and common substrate voltage regulation units are essential circuit elements that must be integrated into a DDIC. Figure 5 shows a block diagram of a gamma correction circuit and a common substrate voltage regulation unit. As shown in FIG5 , the electronic chip 12 (DDIC) further includes a gamma correction circuit 122 and a common substrate voltage adjustment unit 123. The gamma correction circuit 122 includes a reference voltage generating unit 1221 and a gamma voltage generating unit 1222. The reference voltage generating unit 1221 is configured to generate a first maximum reference voltage (V _GMP ) and a first minimum reference voltage (V _GSP ), and the gamma voltage generating unit 1222 is configured to generate a plurality of gamma voltages (V _gamma ) based on the first maximum reference voltage and the first minimum reference voltage. On the other hand, as shown in FIG. 4 and FIG. 5 , the electronic chip 12 (DDIC) further includes a common substrate voltage regulating unit 123 configured to generate and transmit a first common substrate voltage (VCOM) to the OLED display panel 11 .

Therefore, in a feasible embodiment, the temperature compensation unit 121 can also be configured to generate a reference voltage adjustment signal based on the temperature sensing data and transmit it to the reference voltage generation unit 1221, so that the reference voltage generation unit 1221 generates and transmits a second maximum reference voltage (i.e., adjusted V _GMP ) and a second minimum reference voltage (i.e., adjusted V _GSP ) to the gamma voltage generation unit 1222. In this way, the gamma voltages (V _gamma ) output by the gamma voltage generating unit 1222 to the multiple source driver modules 120 of the electronic chip 12 are adjusted accordingly, and the data voltages (V DATA ) output by each source driver module 120 to its corresponding pixel circuit 112 are also adjusted, thereby achieving temperature-based display driver compensation.

As shown in Figures 4 and 5 , since the cathode of each OLED element 111 is coupled to the first common substrate voltage (VCOM), in another possible embodiment, the temperature compensation unit 121 can also be configured to generate a common substrate voltage adjustment signal based on the temperature sensing data and transmit it to the common substrate voltage adjustment unit 123, causing the common substrate voltage adjustment unit to generate and transmit a second common substrate voltage (i.e., the adjusted VCOM) to the OLED display panel 11, thereby achieving temperature-based display drive compensation.

Furthermore, as shown in Figures 4 and 5, electronic engineers familiar with the design and fabrication of display driver chips also know that the electronic chip 12 (DDIC) is further provided with a dimming signal generating unit 124 for generating and transmitting a dimming signal (EM) to the fifth TFT element M5 and the sixth TFT element M6. Therefore, in another feasible embodiment, the temperature compensation unit 121 can be configured to generate a duty cycle adjustment signal based on the temperature sensing data and transmit it to the dimming signal generating unit 124, thereby controlling the dimming signal generating unit 124 to correspondingly change the duty cycle of the dimming signal, thereby implementing the display driver compensation operation.

Figure 6 is a first diagram illustrating the electronic chip 12 shown in Figure 3 during its standby, power-on, and normal display operation. As shown in Figures 3, 4, 5, and 6, when the first embodiment is applied, since the electronic chip 12 and the temperature compensation unit 121 are disabled during the sleep-in period, the host computer 2 does not read temperature data from a temperature sensor within the electronic chip 12. Consequently, the temperature compensation unit 121 is unable to obtain the current temperature reported by the host computer 2. Consequently, as shown in Figure 6, the temperature compensation unit 121 displays an unupdated temperature reading of 22°C.

Furthermore, during the chip power-up period, the electronic chip 12 is also disabled from driving the OLED display panel 11. Therefore, according to the first embodiment of the present invention, the temperature compensation unit 121 is also disabled from performing the display drive compensation operation. Consequently, as shown in FIG6 , even if the host computer 2 reads multiple temperature sensing data from the temperature sensor within multiple time intervals, the host computer 2 will not send updated temperature sensing data to the temperature compensation unit 121. Therefore, the temperature sensing data received by the temperature compensation unit 121 remains at the unupdated 22°C.

Finally, during the normal display drive period, the temperature compensation unit 121 receives the temperature sensing data (i.e., 46°C) read from the temperature sensor by the host computer 2 during a frame display interval. Therefore, during the first frame display interval of the normal display drive period, the temperature compensation unit 121 performs a display drive compensation operation based on the 46°C temperature sensing data. Furthermore, during the second frame display interval, the temperature compensation unit 121 performs a display drive compensation operation based on the 48°C temperature sensing data.

As shown in FIG6 , during the 0th frame display interval during the normal display drive period (i.e., the last frame display interval during the power-on period), the OLED display panel 11 displays a completely black screen because it is not driven by the electronic chip 12. Furthermore, during the 1st frame display interval during the normal display drive period, it suddenly displays a high-brightness screen due to display drive compensation based on a dramatic temperature change (22°C to 46°C). In other words, the temperature compensation unit 121 does not receive the real-time updated temperature sensing data during the power-on period and suddenly receives the temperature sensing data during the normal display driving period. The reception error of the temperature sensing data causes the OLED display panel 11 to suddenly display a high-brightness image in the first frame display area during the normal display driving period.

In summary, although the first embodiment of the temperature-based display drive compensation method of the present invention can implement temperature-based display drive compensation, it still needs to be improved.

Second embodiment

In view of this, the present invention further proposes a second embodiment of the temperature-based display drive compensation method. FIG7 is a flow chart of the temperature-based display drive compensation method of the present invention. As shown in Figures 7, 3, 4, and 5, according to a second embodiment, the temperature-based display drive compensation method of the present invention includes the following steps: During a chip power-on period, enabling the temperature compensation unit 121 to perform a display drive compensation operation based on temperature sensing data; and During a normal display drive period following the power-on period, continuously enabling the temperature compensation unit 121 to perform the display drive compensation operation.

FIG8 is a second diagram showing the electronic chip 12 shown in FIG3 during the standby period, the power-on period, and the normal display driving period.

As shown in FIG8 , during the chip power-on period, the electronic chip 12 is not enabled to drive the OLED display panel 11 for display; however, according to the second embodiment (as shown in FIG7 ), the temperature compensation unit 121 is enabled to perform the display drive compensation operation. That is, the host computer 2 reads a plurality of corresponding temperature sensing data from the temperature sensor during a plurality of time intervals during the chip power-on period, and sends updated temperature sensing data (as shown in FIG8 , 25°C, 29°C, 35°C, 40°C, 43°C, 46°C) to the temperature compensation unit 121, so that the temperature compensation unit 121 performs the corresponding display drive compensation operation according to the updated temperature sensing data in each time interval.

Furthermore, during the normal display drive period, the temperature compensation unit 121 is continuously enabled to perform the corresponding display drive compensation operation within each time interval. Therefore, during the 0th frame display interval (i.e., the last frame display interval during the power-on period) during the normal display drive period, the temperature compensation unit 121 receives the temperature sensing data of 43°C transmitted by the host computer 2 and performs a display drive compensation operation based on the 43°C temperature sensing data. Continuing, during the first frame display interval of the normal display drive period, the temperature compensation unit 121 receives the temperature sensing data of 46°C transmitted by the host computer 2 and performs a display drive compensation operation based on the 46°C temperature sensing data. It is worth noting that, as shown in FIG8 , when performing the display drive compensation operation, the temperature compensation unit 121 performs K-order compensation, where K is a positive integer such as 6.

That is, the temperature compensation unit 121 does not fully compensate all at once during the display drive compensation operation to prevent the OLED display panel 11 from experiencing a sudden brightening of the display screen when switching from the power-up phase to the normal display drive phase. More specifically, the temperature compensation unit 121 gradually increases the compensation effect within the K-frame display interval. In this way, the brightness of the display screen of the OLED display panel 11 is smoothly dimmed to a more accurate specified value within the K-frame display interval.

Thus, the above description has fully and clearly explained the temperature-based display drive compensation method of the present invention; and, from the above description, it can be seen that the present invention has the following advantages:

(1) The present invention provides a temperature-based display driver compensation method, which is executed by a display driver chip containing a temperature compensation unit, thereby performing temperature-based display driver compensation on an OLED panel. In this way, when the display driver chip switches from a chip power-on period to a normal display driver period, the display screen will not appear suddenly bright or suddenly dark. At the same time, the temperature compensation unit will perform dynamic compensation operations in each temperature change range to achieve smooth dimming of the display screen.

(2) Furthermore, the present invention also provides an electronic chip for performing display driving on an OLED display panel and including a temperature compensation unit; the electronic chip is characterized in that the electronic chip performs the temperature-based display driving compensation method of the present invention as described above to realize temperature-based display driving compensation.
