The display device of this embodiment includes an active matrix substrate 10, a color filter substrate (not shown) facing the active matrix substrate 10, and a liquid crystal between the active matrix substrate 10 and the color filter substrate. Layer (not shown). Referring to FIG. 1 , a light sensing module 30 is disposed on an active matrix substrate 10 . However, in another embodiment, the light sensing module 30 can be disposed on a color filter substrate (not shown). Such modifications or variations have common knowledge in the field. The description can be made in accordance with the following description, and thus the related description of the modifications and variations will be omitted. The light sensing module 30 has a function of preventing noise interference, and is spaced apart from the first circuit of the display device, and includes a light sensing device 20 and a protective wire 31. In this embodiment, the first circuit may be a first common line 41 disposed on the active matrix substrate 10, and the first common line 41 is coupled to the common electrode (Vcom electrode) or coupled to the ground end ( Ground). The light sensing device 20 is disposed on the active matrix substrate 10 and includes a light sensor 21 and a light sensing signal line 22 coupled to the light sensor 21 . The protective wiring 31 has a conductive function and surrounds the light sensing device 20 for providing a shielding function to isolate unnecessary interference signals, such as interference signals from the adjacent first shared wiring 41.
換句話說，由於光感測裝置20係為敏感的元件，易受光感測裝置20以外之其他外部電路(例如本實施例的第一共用配線41)的干擾而影響其感測結果的準確度，或因外部電路的干擾產生瞬時間的擺動而影響其感測結果的穩定度。因此以本實施例的方式，防護配線31可以降低光感測裝置20被第一共用配線41干擾的程度，而能夠測得準確度較高或穩定度較高的感測結果。其結果是，當顯示裝置依據光感測裝置20所測得之環境照明的強度以對應調整顯示裝置的光源亮度時，能夠提供較適當的亮度及較不易閃爍，而提高顯示的品質。本實施例中的防護配線31的材料並不予以限定，僅要具導電功能以產生屏敝效應即可，其可以為一金屬層或一氧化銦錫層。防護配線31可以耦接至地端(ground)或是耦接至一個固定的直流電壓。另外，本實施例中的防護配線31的佈局方式也不限定如第1圖所示需包圍環繞全部的光感測裝置20，即使是環繞一部分的光感測裝置20而有達到效果也屬於本發明的範疇。In other words, since the light sensing device 20 is a sensitive component, it is susceptible to interference from external circuits other than the light sensing device 20 (for example, the first shared wiring 41 of the present embodiment) to affect the accuracy of the sensing result. Or, due to interference from an external circuit, an instantaneous swing is generated to affect the stability of the sensing result. Therefore, in the manner of the present embodiment, the protective wiring 31 can reduce the degree of interference of the light sensing device 20 by the first common wiring 41, and can detect the sensing result with higher accuracy or higher stability. As a result, when the display device adjusts the brightness of the light source of the display device according to the intensity of the ambient illumination measured by the light sensing device 20, it can provide more appropriate brightness and less flicker, thereby improving the quality of the display. The material of the protective wiring 31 in this embodiment is not limited, and only has a conductive function to produce a screen effect, which may be a metal layer or an indium tin oxide layer. The guard wire 31 can be coupled to a ground or coupled to a fixed DC voltage. In addition, the layout of the protective wiring 31 in the present embodiment is not limited to the light sensing device 20 that needs to surround all of the light sensing devices 20 as shown in FIG. 1 , and even if it is surrounded by a part of the light sensing device 20 , the effect is also The scope of the invention.

The light sensing device 20 is coupled to the driver 53 for the driver. 53 adjusts the brightness of the display device according to the sensing result of the light sensing device 20. Preferably, both ends of the guard wire 31 are also coupled to a ground end 59 of the driver 53. The protective wiring 31 is grounded through the grounding end 59 of the driver 53, and an additional circuit for grounding the shield wiring 31 on the active matrix substrate 10 can be reduced, and the circuit layout on the active matrix substrate 10 can be simplified.

Fig. 5A is a cross-sectional view taken along line BB of Fig. 4. Fig. 5B is a cross-sectional view taken along line CC of Fig. 4. Referring to FIG. 4 , FIG. 5A and FIG. 5B , the display device 11 of the present embodiment comprises an active matrix substrate 10 and a color filter substrate 90 facing the active matrix substrate 10 . A common electrode 51 is provided on the color filter substrate 90. The common electrode 51 can be regarded as an external circuit of the light sensing device 20 with respect to the light sensing device 20, and provides an interference signal to the light sensing device 20. The protective wiring 31 is disposed on the photo sensor 21 or the photo-sensing signal line 22 of the photo-sensing device 20, so that a portion of the guard wiring 31 is located between the common electrode 51 and the photo sensor 21, as shown in FIG. 5B. And another portion is located between the common electrode 51 and the photo-sensing signal line 22, as shown in FIG. 5A.

圖6為本發明另一實施例之顯示裝置沿於圖4之BB線的剖面圖。圖6實施例與圖5A及5B實施例相似，以下僅說明兩實施例相異部分。本實施例中，將光感測裝置20的光感測訊號線22(或光感測器21)設於主動式矩陣基板10的一特定區域，使得光感測裝置20的光感測訊號線22(或光感測器21)沿主動元件基板10之法向量在彩色濾光片基板90上形成一正投影區Sd，且此正投影區Sd未重疊於共用電極51。依據此設計，使光感測裝置20的光感測訊號線22與共用電極51錯開，能夠更進一步降低光感測裝置20被共用電極51干擾的程度。另外，由於光感測訊號線22與共用電極51已經間隔一距離，因此第二絕緣層54與導電配線55也可以省略，仍然有降低被共用電極51干擾的效果。Figure 6 is a cross-sectional view of the display device taken along line BB of Figure 4 in accordance with another embodiment of the present invention. The embodiment of Fig. 6 is similar to the embodiment of Figs. 5A and 5B, and only the different portions of the two embodiments will be described below.

According to this design, the photo-sensing signal line 22 of the photo-sensing device 20 is shifted from the common electrode 51, and the degree to which the photo-sensing device 20 is interfered by the common electrode 51 can be further reduced. In addition, since the photo-sensing signal line 22 and the common electrode 51 have been spaced apart by a distance, the second insulating layer 54 and the conductive wiring 55 may be omitted, and the effect of being disturbed by the common electrode 51 may still be reduced.
