Problems solved by technology

[0005] Based on the point-control interaction method of the above-mentioned iPhone, if a large-size touch screen is added to the audio-visual entertainment system, the corresponding functions can also be realized, but the touch screen ( Such as resistive touch screen, capacitive touch screen), the control signal input must rely on the finger or pen tip to touch the display screen, so it cannot be remotely controlled at a certain distance. It can be seen that point-controlled interaction through touch is very important for audio-visual entertainment systems. is impractical

Embodiment 1

[0053] refer to figure 1 The display device with built-in induction includes a display screen 1 , a light sensing device, a monitoring device and an operating beam generating device 2 .

[0054] The photosensitive device includes a plurality of photosensitive devices 3 , and each photosensitive device 3 is arranged on the display surface of the display screen 1 . The photosensitive device 3 can sense the light incident on the photosensitive device 3 and its changes. When the photosensitive device 3 senses the change of incident light, it converts it into a change of electrical signal, that is, generates a photosensitive signal.

[0055] The operating beam generating device 2 can use a laser pointer (also can be other devices that can generate a beam), and the operating beam generating device 2 generates an operating beam 4 (such as a laser beam). When the operating beam 4 is irradiated on the position of a certain photosensitive device 3 , the light incident on the photosens...

Embodiment 2

[0076] In this embodiment, the signal of the photosensitive array is led out to the monitoring device by means of series lead-out, such as Figure 15 As shown, its characteristics are: the photosensitive array includes two sets of sub-matrixes nested with each other, the Y photosensitive sub-matrix and the X photosensitive sub-matrix, and the two sets of sub-matrices are respectively composed of a Y photosensitive device 3-1 and an X photosensitive device 3-2 (a photosensitive The device 3 corresponds to a position coordinate information, wherein the position coordinate information of the Y photosensitive device 3-1 only includes the Y-axis coordinate, and the X photosensitive device 3-2 only includes the X-axis coordinate), and configures the X-direction signal line Xn for the Y photosensitive sub-matrix (Xn1, Xn2, Xn3...), configure the Y direction signal line Ym (Ym1, Ym2, Ym3...) for the X photosensitive sub-matrix; in the Y photosensitive sub-matrix, the Y photosensitive d...

Embodiment 3

[0083] On the basis of Embodiment 1, only the structure of the photosensitive device 3 is improved, such as Figure 19 and Figure 20 As shown, the feature of the photosensitive device 3 is: an ohmic contact layer 38 is arranged between the two extraction electrodes (i.e. the first extraction electrode 32 and the second extraction electrode 33) and the silicon film, and the ohmic contact layer 38 is partially extended to the photosensitive window.

[0084] Since the extension portion 381 of the ohmic contact layer 38 has light transmittance and electrical conductivity, light can pass through the extension portion 381 and enter the photosensitive channel 34 to excite photo-induced carriers, which can move vertically to The extended portion 381 of the ohmic contact layer 38 is guided into the lead-out electrode by the conductivity of the ohmic contact layer 38 . Adopting this design scheme can increase the intensity of the photo-induced leakage current between the two electrod...

Abstract

A display device of built-in sensitive device comprises a display screen. The present invention is characterized in that the display device also comprises a light sensitive device and a monitoring device; the light sensitive device comprises a plurality of light sensors; the light sensors sense the change of incident rays and generate light sensitive signals; the electric signals of all light sensors are monitored by the monitoring device; when the light sensitive signal generated by a certain light sensor is monitored, the position coordinate information of the light sensor, stored in the monitoring device, is extracted, and the position coordinate information of the light sensor is fed back to the external. The variation of the light environment in a certain position on the surface of the display screen can be sensed when the display device is operated. The position information is input, so the purpose of information input is realized. The display device is optimally operated by illuminating operating light beams generated by a light beam generator to the specific position of the display surface of the display screen. The display device integrates the functions of remote control and dot control. A built-in sensitive device is optimally adopted. The light sensors share the film structure necessary for thin film transistors.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device capable of sensing the change of the light environment on the surface to achieve the purpose of information input. Background technique [0002] The current audio-visual entertainment technology has gradually developed from a traditional simple system relying on TV signals and hard media media (such as CDs) to a multimedia system relying on the Internet and software media media, and its application content is also played by traditional audio-visual media. Gradually enriched, extending the network, games and other functions. For this reason, various related manufacturers have introduced corresponding technologies. For example, Microsoft took the lead in launching the "Win XP Media Center Edition 2005" operating system in 2005. Enjoy digital entertainment content such as photos, movies, music, and TV efficiently. In addition to supporting the mouse and keyboard used by ...
