Embodiment Construction

[0012] The technical solution provided by the present invention is: add focusing photometering equipment to the TV to detect the light receiving data of human eyes and faces, process the receiving light data and transmit it to the CPU of the TV, and the CPU judges whether the focus is accurate or not according to the receiving light data. It is necessary to adjust the focus metering device; and adjust the backlight of the TV set according to the light receiving data of human eyes and faces detected by the focus metering device when the focus metering device is in accurate focus.

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Abstract

The invention is suitable for the technical field of televisions, in particular provides a television and a backlight-adjusting method thereof. The television comprises an optical receiving device, an image sensor, a signal-processing converter, a CPU and a backlight control module, wherein the optical receiving device is used for receiving light reflected by the eyes of television viewers and transmitting the received light to the image sensor which is used for receiving the light transmitted by the optical receiving device, generating an optical signal according to the strength of the received light and outputting the optical signal to the signal-processing converter; the signal-processing converter is used for converting the optical signal transmitted by the image sensor into a digitalsignal and outputting the digital signal to the CPU; and the CPU is used for comparing a numerical value of the digital signal with a set standard regional value, calculating adjusting data accordingto the compared different value and inputting the adjusting data into the backlight control module which is used for adjusting the backlight of the television according to the adjusting data.

Description

technical field [0001] The invention belongs to the technical field of televisions, in particular to an LCD television with an adjustable backlight and a method for adjusting the backlight thereof. Background technique [0002] At present, the backlight adjustment of LCD TVs rarely takes into account the influence of external light on the backlight adjustment, and a few products use some photosensitive devices to automatically adjust the backlight according to changes in ambient light, thereby reducing user eye fatigue and protecting the user's eyesight. At the same time, it can also save energy. In the prior art, some LCD TVs adjust the backlight of the TV by testing the brightness of the ambient light, that is, install a light sensor that can detect the brightness of the ambient light for the TV, and collect some parameters that are helpful for adjusting the brightness of the backlight , sending the collected parameters to a CPU preset with an analysis and processing prog...
