Embodiment Construction

[0040] The design of the light sensor according to the embodiment of the present invention will be described below with reference to related drawings, wherein the same components will be described with the same reference symbols. In addition, it should be noted that the term "layer A is formed (or arranged) on layer B" in this specification is not limited to the aspect that layer A directly touches the surface of layer B, for example, there is still a gap between layer A and layer B. Intervals between other layers are also covered by this term.

[0041] figure 1 It is a top view of a substrate of a display device according to an embodiment of the present invention. 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 located between the active matrix substrate 10 and the color filter substrate. layers (not shown). Please refer to figure 1 , a light se...

Abstract

The invention provides an optical sensing module with protecting function and a display device. The optical sensing module is arranged on a first substrate and keeps a certain interval with an external circuit. The optical sensing module comprises an optical sensing device and a protecting wire, wherein the optical sensing device is arranged on the first substrate, and the protecting wire has conducting function and is arranged between the external circuit and one part of the optical sensing device. According to the design of the embodiments of the invention, the protecting wire has conducting function and is arranged between optical sensing device and the external circuit thereof, thereby being capable of generating the shielding effect, reducing the interference of the optical sensing device caused by the external circuit and further obtaining the sensing result with high accuracy or high stability. The display device of the embodiment of the invention can supply appropriate brightness, be difficult to flicker and improve the display quality.

Description

technical field [0001] The present invention relates to a light sensor and a display device, in particular to a light sensor with protection function and a display device with the light sensor. Background technique [0002] In the prior art, an ambient light sensor is generally installed on the display device to measure the intensity of ambient lighting and adjust the brightness of the light source of the display device accordingly, so as to provide a good display at the same time. effect and reduce power consumption requirements. U.S. Patent No. 5,831,693 discloses a technology for a display device with a light sensor. It uses a thin-film process to place light-sensing elements around an active substrate, and then converts the light signal into an electrical signal through an operational amplifier. The signal is used for the display device to adjust the brightness of the light source. U.S. Patent No. 7053967 discloses another technology of a display device with a light se...
