Problems solved by technology

[0014] It can be seen that the above-mentioned existing display devices that can sense ambient light obviously still have inconveniences and defects in structure and use, and need to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Embodiment Construction

[0050] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, Features and their functions are described in detail below.

[0051] The present invention provides a display device capable of processing signals from a plurality of light sensors, each sensor being exposed to ambient light. Partial occlusion of ambient light at one or a portion of the light sensor locations is identified to obtain an accurate estimate of ambient light levels.

[0052] The display device and method of the present invention can be applied to figure 1 and figure 2 The known structure shown.

[0053] image 3 It is a flow chart of the control method of an embodiment of the present invention.

[0054] In step 50, first obtain signals from a plurality of integrated light sensors.

[0055] In step 52, the magnitudes of the light sensor signals are compared. By this step, local o...

Abstract

A display device comprises an illumination source (12), a display modulator (10) for modulating the light provided by the illumination source and an integrated light sensor arrangement (14) to detect a light level. Light sensor signals from a plurality of light sensors are processed such that localised shielding of the ambient light at the location of one or more of the light sensors is identified. An accurate estimate of the ambient light level can then be obtained.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device using a luminous light source, the display device can adjust the light of the luminous light source and can sense ambient light. Background technique [0002] A liquid crystal display is the most common example of a display device with an adjustable function, which generally includes an active plate, a passive plate, and a liquid crystal material placed between the two plates. The active board includes an array of transistor switching devices, and typically each transistor is associated with a pixel of the display. In addition, each pixel is associated with the pixel electrodes on the active board. When the signal is sent to the pixel electrodes, the brightness of each pixel can be controlled. [0003] Ambient light can strongly affect the performance of display devices with adjustable light sources. In addition, the intensity of ambient light can also affect the perf...
