Abstract

PURPOSE:To perform time display with a comparatively simple means, by overlapping a time display panel on a picture display panel. CONSTITUTION:When no voltage is applied between electrodes 16 and 18, an incident light linearly deflected at a deflection plate 14 transmits deflection plates 11, 12 and only a reflection plate 13 is pictured. In case of television picture display, since a voltage is applied to an electrode 7 for scanning and an electrode 9 for signals, a picture is obtained and it can be observed through a time display panel. In case of time display, the television picture display is stopped and a voltage is applied between the electrodes 16 and 18 for time display. Thus, liquid crystal 17 between the electrodes 16 and 18 is excited and the time is displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a liquid crystal television display device with a clock, and particularly to an improved display section thereof.

TECHNICAL BACKGROUND OF THE INVENTION With the development of electronics technology, the display means of television receivers has changed from means using cathode rays to flat panel display means, and has become ultra-small and thin. This flat panel display means uses light emitting diodes as display elements, liquid crystals, electroluminescence, etc. in each building. j It is illuminated and realized. Among these, liquid crystal matrix panel display means using liquid crystal is extremely thin, and Ia c
181"R power, when applied to a television home display, it became possible to realize a pocketable television receiver i141 as shown in Fig. 1. This television receiver The outer case 1 has a thin box shape, and the display part 2 is formed on the upper part of the front surface.If it has such a shape, it will cost $ 1 for 494 bands.
It is 1.

Note that 3 is a T-channel display section, and 4 is a tuning dial. The cross section of the liquid crystal display panel of this television receiver 111J is shown in FIG. 111” 1st. On the opposite surface of the second glass substrate 6°10, force,

．． 9 are arranged in stripes, and liquid crystals 8 are formed between them. Then, each intersection of 龜siy, 9 becomes a pixel and 1. Add between magnetic poles 1.9 and 4 below E
The structure is such that the liquid crystal in the 11411 portion is excited by the field. There is a twisted nematic (TN) type of liquid crystal, in which the molecules of the liquid crystal are placed in a horizontal to horizontal state by the distribution process of the liquid crystal, and the molecules of the liquid crystal are placed in a horizontal to vertical state, so that they are close to each other with only 7.9 degrees of rotation. We are distributing the information so that it will be done accordingly.”
- The lower deflection plates 11 and 12 are also orthogonal to each other in a 1 m optical relationship. If no magnetic pressure is applied to the sub magnetic pole 7.9j in this bad condition, the incident light that has been polarized by 1 self-line in the first sieve 11 will be transmitted up to the reflection number 13 because the polarized 90 Jf will rotate. It reflects a number of reflections, but 4, +! When a voltage is applied between ii and 7.9, in the above-mentioned twisted nematic cylindrical crystal, the long axis direction of the liquid crystal molecules is oriented in the same direction as the boundary, so that the incident light that is deflected along the 1st axis in the 1st direction is teeth,? 4I
It was carved in J2's 1r111 Dokyo 12. When many gradations from white to black are required, as in the case of a television receiver 1ψ~, if the #a pressure applied to the magnetic pole 7.9 is controlled according to the video signal, the transmission of incident light becomes unclear. The liquid crystal panel can display television images.

Problems with the Background Art By the way, in the above-mentioned television receiver,
When displaying the time, it should be provided as shown in Figure 1 in the hour 1j display tip 5 Jk:
It is conceivable to simultaneously display N children on the television 1iIl image on the I song. However, in the case of 1Ii1, since the time display device is newly provided in a separate part from the display part 2, the shape becomes larger and the exterior design has to be redone.
Since the display is always displayed at the same time as 11, it becomes uneconomical to use a small receiver using a power source such as a dry cell, and a new circuit for controlling the time signal must be added to the television signal processing circuit itself. No.

Purpose of the Invention The present invention has been made in view of the above-mentioned problem, and it is possible to provide a time display means by relatively simple means.
Moreover, it is an object of the present invention to provide a liquid crystal television display device with a clock that does not require major design changes.

Examples of the invention Embodiments of this invention will be described below with reference to the drawings.

Figure 3 shows 11! according to an embodiment of this invention. This figure shows a cross section of the illumination surface, and the same parts as those in Figure 2 will be described with the same reference numerals. That is, in the present invention, the upper part of the first deflection plate IJ is

is a glass substrate, and glass substrate J9. On the opposite surface of J5, 4 (Jjxtt, xe) for time display is provided. That is, C 1.! .

A liquid crystal 17 is sealed between the two abrasive poles 1B and 16. Furthermore, a third deflection plate 14 is arranged i1 on the plate surface 5 of the TF lath & plate] 5. 9g1. Second deflection plate 1
The ll!111 display panel is composed of 1.12, glass substrate 6.10, (pole 7.9, and liquid crystal 8.

It operates in the same manner as described in FIG. 2 and can display television images. Next, the operation of the time display panel section will be explained. Liquid crystal) 7 is a nematic type liquid crystal, which has a horizontal distribution pattern by processing the surfaces of magnetic poles ie and is, and is distributed perpendicularly to the housing on the surfaces of 44476 and 18. However, the arrangement of the liquid crystal on the transparent magnetic pole 7 for set meals on the inner curve of the glass substrate 6 and the arrangement of the liquid crystal nozzle on the surface of the i-frame 18 are the same.

When oriented in this way, the third deflection plate 14 and the first deflection plate 11 become directly connected to each other.

According to the above display means, firstly, when no magnetic pressure is applied between the negative poles 16 and 18, the incident light linearly polarized by the third deflection plate 14 is rotated by 9oi + polarization, so that 1
Similarly, the second deflecting plate 12 also passes through the second deflecting plate 12.
! ! ! Only the reflection plate 13 is reflected. When a television image is displayed next, heavy pressure is applied to the set meal electrode 7 and the signal electrode 9, so one image is displayed in the same way as in the series of images. You can see through the time display panel.

If you want to display the time next time, stop the television image display and select 4. Plum 1e.

Switch to apply wax pressure between 18 and 18. As a result, the liquid crystal between the transparent pattern electrode selected for time display and the common electrode 18 is excited, and only that part receives input light. The clock is turned on and the time is displayed. 412th! J is an example of the display. Panel 2 applied the merits of the case.

Effects of the Invention As described above, in this device, a time display panel is simply added to the image display panel, and there is no need for a special circuit design for the image processing circuit.

Furthermore, since the display section displays the time in the area that was originally used, there is no need to provide a separate new time display section. It should be noted that by using a modified circuit, it can be installed between the small seedlings in the case. In addition, by doing this, only the time display can be obtained when the time display is desired, and there is less need for one-shot trade compared to the case where the image is displayed at the same time.

As described above, the present invention can provide a liquid crystal television display device 1 with a clock in which a time display means can be provided by relatively simple means, and which does not require major design changes to conventional devices. .
